4 Installing the Host Bus Adapters for the E2600 Controller-Drive Tray

4.1 Key TermsHBA host portThe physical and electrical interface on the host bus adapter (HBA) that provides for the connection between the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World Wide Identifier (WWID) and each HBA host port has a unique WWID.

HBA host port world wide nameA 16-character unique name that is provided for each port on the host bus adapter (HBA).

host bus adapter (HBA)A physical board that resides in the host. The HBA provides for data transfer between the host and the controllers in the storage array over the I/O host interface. Each HBA contains one or more physical ports.

4.2 Things to Know – Host Bus Adapters and Ethernet Network Interface Cards– The E2600 controller-drive tray supports dual 6-Gb/s SAS host connections and optional

host interface cards (HICs) for dual 6-Gb/s SAS, four 1-Gb/s iSCSI, two 10-Gb iSCSI, and four 8-Gb/s FC connections. The connections on a host must match the type (SAS HBAs for SAS, FC HBAs for FC, or iSCSI HBAs or Ethernet network interface cards [NICs] for iSCSI) of the HICs to which you connect them. For the best performance, HBAs for SAS and FC connections should support the highest data rate supported by the HICs to which they connect.

– For maximum hardware redundancy, you must install a minimum of two HBAs (for either SAS or FC host connections) or two NICs or iSCSI HBAs (for iSCSI host connections) in each host. Using both ports of a dual-port HBA or a dual-port NIC provides two paths to the storage array but does not ensure redundancy if an HBA or a NIC fails.

– Most of the HBAs, as shipped from the vendor, require updated firmware and software drivers to work correctly with the storage array. For information about the updates, refer to the website of the HBA vendor.

NOTICE! You can use the Compatibility Matrix to obtain information about the supported models of the HBAs and their requirements. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer Partner Program link. Check its Compatibility Matrix to make sure you have an acceptable configuration.

4.3 Procedure – Installing Host Bus Adapters1. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer

Partner Program link. Check its Compatibility Matrix to make sure you have an acceptable configuration.The Compatibility Matrix provides this information:

– The latest hardware compatibility information– The models of the HBAs that are supported– The firmware requirements and the software requirements for the HBAs

2. Install your HBA according to the vendor documentation.

3. Install the latest version of the firmware for the HBA. You can find the latest version of the firmware for the HBA at the HBA vendor website.

4. Reboot or start your host.5. While your host is booting, look for the prompt to access the HBA BIOS utility.6. Select each HBA to view its HBA host port world wide name.7. Record the following information for each host and for each HBA connected to the

storage array:– The name of each host– The HBAs in each host– The HBA host port world wide name of each port on the HBA

The following table shows examples of the host and HBA information that you must record.

NOTICE! If your operating system is Windows Server 2008 Server Core, you might have additional installation requirements. Refer to the Microsoft Developers Network (MSDN) for more information about Windows Server 2008 Server Core. You can access these resources from www.microsoft.com.

NOTICE! The remaining steps are general steps to obtain the HBA host port world wide name from the HBA BIOS utility. If you have installed the host context agent on all of your hosts, you do not need to perform these steps. If you are performing these steps, the actual prompts and screens vary depending on the vendor that provides the HBA. Also, some HBAs have software utilities that you can use to obtain the world wide name for the port instead of using the BIOS utility.

6.1 Key Termsdirect topologyA topology that does not use a switch.

switch topologyA topology that uses a switch.

topologyThe logical layout of the components of a computer system or network and their interconnections. Topology deals with questions of what components are directly connected to other components from the standpoint of being able to communicate. It does not deal with questions of physical location of components or interconnecting cables. (The Dictionary of Storage Networking Terminology)

6.2 Things to Know – Host Channels

– Each controller has from two to six host ports.– Two of the host ports are standard and support 6-Gb/s SAS data rates.– Two to four of the host ports are optional, and, if present, are located on a host interface

card (HIC). The following types of HICs are supported:– Two SAS connectors at 6-Gb/s– Four iSCSI connectors at 1-Gb/s– Two iSCSI connectors at 10-Gb/s– Four FC connectors at 8-Gb/s

6.3 Procedure – Connecting Host Cables on an E2600 Controller-Drive Tray

The type of HICs (SAS, FC, or iSCSI) must match the type of the host bus adapters (HBAs) or network interface cards (for iSCSI only) to which you connect them. See the examples in Section 6.4 Example cabling patterns, page 37.1. Perform one of these actions:

– You are using an FC HIC Go to step 2.

– You are using either a SAS or an iSCSI HICGo to step 4. Connections for both SAS and iSCSI use copper cables with RJ-45 con-nectors and do not require SFP transceivers.

2. Make sure that the appropriate type of SFP transceiver is inserted into the host channel.3. If a black, plastic plug is in the SFP transceiver, remove it.4. Perform one of these actions:

– You are using either a SAS or an iSCSI HICStarting with the first host channel of each controller, plug one end of the cable into the host channel.

– You are using an FC HICStarting with the first host channel of each controller, plug one end of the cable into the SFP transceiver in the host channel.

The cable is either an Ethernet cable with RJ-45 connectors for 1-Gb/s iSCSI or 6-Gb/s SAS connections, or a fiber-optic cable for FC connections.

5. Plug the other end of the cable either into an HBA in the host (direct topology) or into a Note:switch (fabric topology).Note:

The SAS host interface does not support a switch topology.


NOTICE! Make sure that you have installed the HBAs. Refer to the documentation for the HBAs for information about how to install the HBA and how to use the supplied configuration utilities.

NOTICE! If Remote Volume Mirroring connections are required, do not connect a host to the highest numbered host channel.



6. Affix a label to each end of the cable with this information. A label is very important if you need to disconnect cables to service a controller. Include this information on the labels:– The host name and the HBA port (for direct topology)– The switch name and the port (for fabric topology)– The controller ID (for example, controller A)– The host channel ID (for example, host channel 1)Example label abbreviation

– Assume that a cable is connected between port 1 in HBA 1 of a host named Engineering and host channel 1 of controller A. A label abbreviation could be as follows.

7. Repeat step 3 through step 6 for each controller and host channel that you intend to use.

8.2 Things to Know – E2600 Controller-Drive Tray

– The E2600 controller-drive tray supports the DE1600 drive tray for expansion.– The maximum number of drive slots in the storage array is 96 (expandable to 192,

including the 12 or 24 drive slots in the controller-drive tray. Exceeding 96 (or 192) drive slots makes the storage array invalid. The controllers cannot perform operations that modify the configuration, such as creating new volumes.

– Each controller has one dual-ported SAS expansion connector to connect to the drive trays.

Figure 8.1 Drive Channel Ports on the E2600 Controller-Drive Tray – Rear View

8.3 Things to Know – Drive Trays with the E2600 Controller-Drive Tray– Each DE1600 drive tray can contain a maximum of twelve 8.89-cm (3.5-in.) drives.– The ESMs on the DE1600 drive tray contain two sets of In connectors and one set of Out

connectors.

NOTICE! On the E2600 controller-drive tray, each controller has a pair of levers with handles for removing the controller from the controller-drive tray. One of these handles on each controller is located next to a host connector. The close spacing between the handle and the host connector might make it difficult to remove a cable that is attached to the host connector. If this problem occurs, use a flat-blade screwdriver to push in the release component on the cable connector.

2. If there is a black, plastic plug in the SAS expansion connector of the controller, remove it.

3. Insert one end of the cable into the SAS expansion connector on the controller in slot A in the controller-drive tray.

4. Insert the other end of the cable into the connector with an up arrow on the ESM in slot A in the drive tray.

5. Are you adding more drive trays?– Yes

Go to step 6.

– NoGo to step 9.

Figure 8.8 Connecting a Cable from One ESM to a Second ESM

6. In the ESM in the first drive tray, insert one end of the cable into the connector on the far-right side.

7. In the ESM in the next drive tray, insert the other end of the cable into one of the connectors in the left-center of the ESM.

8. Repeat step 6 through step 7 for each drive tray that you intend to add to the storage array.

NOTICE! Each ESM in a drive tray has three expansion connectors: two on the left-center of the ESM and one in the upper-right side. When connecting from an ESM in one drive tray to an ESM in another drive tray, make sure that you connect the connector on the upper-right to one of the connectors on the left-center. The following figure shows these arrows on an ESM. If the cable is connected either between the two left-center ESM connectors or between two upper-right ESM connectors, communication between the two drive trays is lost.

NOTICE! It does not matter which of the two left-center ESM connectors you use to connect to the expansion connector on the far-right side.



9. To each end of the cables, attach a label with this information:– The controller ID (for example, controller A)– The ESM ID (for example, ESM A)– The ESM connector (In or Out)– The drive tray IDFor example, if you are connecting controller A to the In connector on ESM A in drive tray 1, the label on the controller end of the cable will have this information:

CtA-Dch1, Dm1-ESM_A (left), In – Controller End

The label on the drive tray end of the cable will have this information:

Dm1-ESM_A (left), In, CtrlA

10. If you are installing the controller-drive tray with two controllers, repeat step 2 through step 9 for the controller in slot B in the controller-drive tray.

NOTICE! To connect cables for maximum redundancy, the cables attaching controller B must be connected to the drive trays in the opposite tray order as for controller A. That is, the last drive tray in the chain from controller A must be the first drive tray in the chain from controller B.

out-of-band managementA method to manage a storage array in which a storage management station sends commands to the storage array through the Ethernet connections on the controller.

9.2 Things to Know – Connecting Ethernet Cables

– These Ethernet connections are intended for out-of-band management and have nothing to do with the iSCSI host interface cards (HICs), whether 1Gb/s or 10Gb/s.Ethernet port 2 on each controller is reserved for access by your Customer and Technical Support representative.

In limited situations in which the storage management station is connected directly to the controller tray, you must use an Ethernet crossover cable. An Ethernet crossover cable is a special cable that reverses the pin contacts between the two ends of the cable.

9.3 Procedure – Connecting Ethernet CablesPerform these steps to connect Ethernet cables for out-of-band management. If you use only in-band management, skip these steps.1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.2. Connect the other end to the applicable network connection.3. Repeat step 1 through step 2 for controller B.

NOTICE! Risk of security breachConnect the Ethernet ports on the controller tray to a private network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array might be at risk of being accessed from outside of your network.

E2600 DSA E-Series iSCSI Disk Arrays Connecting the Power Cords | en 61


10 Connecting the Power CordsThe E2600 controller-drive tray and the DE1600 drive tray can have either standard power connections to an AC power source or the optional connections to a DC power source (–48 VDC).

10.1 Things to Know – AC Power Cords– For each AC power connector on the drive tray, make sure that you use a separate power

source in the cabinet. Connecting to independent power sources maintains power redundancy.

– To ensure proper cooling, do not operate a drive tray with one of its power supplies removed.

– You can use the power cords shipped with the controller-drive tray with typical outlets used in the destination country, such as a wall receptacle or an uninterruptible power supply (UPS). These power cords, however, are not intended for use in most EIA-compliant cabinets.

10.2 Things to Know – DC Power CordsIf your controller-drive trays have the DC power option installed, review the following information.

Figure 10.1 DC Power Cable

– Each power-fan canister has two DC power connectors. Be sure to use a separate power source for each power-fan canister in the drive tray to maintain power redundancy. You may, optionally, connect each DC power connector on the same power-fan canister to a different source for additional redundancy.

– A two-pole 30-amp circuit breaker is required between the DC power source and the drive tray for over-current and short-circuit protection.

NOTICE! Make sure that you do not turn on the power to the controller-drive tray or the connected drive trays until this documentation instructs you to do so. For the correct procedure for turning on the power, see Section 11 Turning on the Power and Checking for Problems, page 64.

Continue with the Initial Configuration and Software Installation in these electronic document topics or through the PDF that is available on the SANtricity ES Storage Manager Installation DVD.

11.1 Turning On the Power to the Storage Array and Checking for Problems

1. Turn on both Power switches on each drive tray that is attached to the controller-drive tray. Depending on your configuration, it can take several minutes for each drive tray to complete the power-on process.

2. Turn on both Power switches on the rear of the controller-drive tray. Depending on your configuration, it can take several minutes for the controller-drive tray to complete the power-on process.

3. Check the LEDs on the front and the rear of the controller-drive tray and the attached drive trays.

4. If you see any amber LEDs, make a note of their location.

11.2 Things to Know – LEDs on the E2600 Controller-Drive TrayThe following topics provide details on the LEDs found on the E2600 controller-drive tray.

NOTICE! You must turn on the power to all of the connected drive trays before you turn on the power for the controller-drive tray. Performing this action makes sure that the controllers recognize each attached drive tray.

NOTICE! While the power is being applied to the trays, the LEDs on the front and the rear of the trays come on and go off intermittently.

NOTICE! Before you go to step 2, check the LEDs on the drive trays to verify that the power was successfully applied to all of the drive trays. Wait 30 seconds after turning on the power to the drive trays before turning on the power to the controller-drive tray.

12 Replacing a Drive in an E2600 Controller-Drive TrayIn this procedure, you will replace a failed drive with a new drive.Before you start to replace a drive in the controller-drive tray, gather antistatic protection and a replacement drive.You can determine whether you have a failed drive in two ways:– The Recovery Guru directs you to replace a failed drive.– You locate the failed drive by checking the Drive Service Action Required LED (Figure 1

on page 2).

1. If possible, use the storage management software to create, save, and print a new storage array profile.

2. Did the Recovery Guru direct you to replace a failed drive?– Yes

Go to step 3.

– NoRun the Recovery Guru to identify the failed component.

3. Put on antistatic protection.4. Unpack the new drive.

– Set the new drive on a dry, level surface near the controller-drive tray.– Save all the packing materials in case you need to return the drive.If a fault is detected, the amber Drive Service Action Required LED is on. If you can safely remove the drive, the blue Service Action Allowed LED is on (Figure 1).

CAUTION! Possible equipment damageYou must replace the drive within three minutes after removal to prevent the possibility of overheating the equipment.

CAUTION! Possible loss of data accessNever insert drives into the controller-drive tray without first confirming that the drive firmware level is compatible with the other drives. Inserting a drive with an incorrect firmware level can cause loss of data access. For information about the supported drive firmware levels, contact a Customer and Technical Support representative.

CAUTION! Possible loss of data accessMagnetic fields can destroy all data on the drive and cause irreparable damage to the drive circuitry. To avoid the loss of data access and damage to the drives, always keep drives away from magnetic devices.


NOTICE! Install only drives that are specifically designed for your controller-drive tray and that have been tested and qualified by the factory.

NOTICE! If you accidentally remove an active drive, wait at least 30 seconds, and then reinstall it. For the recovery procedure, refer to your storage management software.

NOTICE! Depending on your configuration, the controller might automatically reconstruct data to the new drive. If the drive tray uses hot spares, the controller might need to perform a complete reconstruction on the hot spare before the controller copies the data to the replaced drive. This reconstruction process increases the time that is required to complete this procedure.

13 Replacing a Controller Canister in the Controller-Drive TrayUse this procedure to add a controller canister to the E2600 controller-drive tray or to replace one that has failed. You can determine whether you have a failed controller canister in two ways:– The Recovery Guru directs you to replace a failed controller canister.– You locate the failed controller canister by checking the Controller Service Action

Required LED.Before you start to replace the controller canister in the controller-drive tray, gather antistatic protection and a new controller canister.When you install a new controller canister, you must remove the battery from the failed controller canister, and install it in the new controller canister. This procedure includes that task.If you are changing your current configuration, you might need to replace these items:– Small Form-factor Pluggable (SFP) transceivers.– Host bus adapters.– Cables – Both SAS and iSCSI use copper cables, and Fibre Channel supports copper

cables and fiber-optic cables.

13.1 Removing a Controller Canister from the Controller-Drive Tray


CAUTION! Possible hardware damageIf you perform this procedure with the power turned on, the equipment might overheat if the controller slot is left open for more than three minutes. To prevent the possibility of overheating, you must insert the controller air blocker into the controller slot when servicing the controller.

NOTICE! Possible loss of data accessIf the controller that you are replacing manages any secure volumes, the new controller will need the correct security key to manage those volumes. After you replace the controller and restore power to the controller-drive tray, you can use SANtricity® ES Storage Manager to load the key from the file in which it was saved. Be sure that such a file exists and that you know the pass phrase required to install the security key before you replace the controller.


NOTICE! You must replace the controller with the power turned on to ensure auto-code synchronization of the native controller firmware to the new controller and to prevent the possibility of an extended outage.

E2600 DSA E-Series iSCSI Disk Arrays Upgrading or Replacing a Host Interface Card in the Controller-Drive Tray | en 111


16 Upgrading or Replacing a Host Interface Card in the Controller-Drive Tray

Use this procedure to add a host interface card (HIC) or replace one that has failed. The replacement HIC can have iSCSI, SAS, or Fibre Channel connections. The E2600 controller-drive tray can mix host interfaces of different types, with some restrictions. In all cases, when host interface types are mixed, both controllers in a duplex controller-drive tray must have the same arrangement of HICs. Each controller must have the same type of HIC in the same relative position as the other controller.

Before you upgrade or replace a HIC, gather antistatic protection and a new HIC. If you are changing your current configuration, you might need to replace these items in addition to the HIC:– Small Form-factor Pluggable (SFP) transceivers.– Host bus adapters.– Cables – Both SAS and iSCSI use copper cable, and Fibre Channel uses copper cable and

fiber-optic cable.– The correct host interface card subplate for the front of the controller (which is included

in this kit).

16.1 Removing the Host Interface Card from the Controller-Drive TrayTo install a host interface card (HIC) or replace a failed HIC, you must first remove the controller canister.


CAUTION! Possible equipment damageOnly a qualified service technician should perform this procedure, or equipment damage might result.

NOTICE! Potential loss of connectivityIf both controllers in a duplex controller-drive tray do not have the same type of HIC in the same relative position, a mismatch results that causes both controllers to lock down (shut down and stop operating).

Make sure that the seven-segment display ribbon cable is still connected to the motherboard connector. If the ribbon cable is not connected, you must lift the center piece of the motherboard connector, and insert the ribbon cable into the motherboard connector.

NOTICE! The ZIF socket is very fragile and is easily broken. Either use your fingers or a screwdriver to gently pry the ZIF socket open.

NOTICE! The front bezel can suddenly pop loose and cause damage to either the front bezel flex harness or the zero insertion force (ZIF) socket that is attached to the controller card. Make sure that you gently angle the front bezel away from the controller canister to allow access to the HIC.

NOTICE! You must place the HIC in the same location in the new controller canister, being careful not to scratch or bump any of the components on the bottom of the HIC or the top of the controller card.

NOTICE! Make sure you have the correct host interface cards, Small Form-factor Pluggable (SFP) transceivers, and host bus adapters. If you are replacing one host interface card (HIC) with a different type of HIC, you might not be able to reuse the SFP transceivers. For more information, refer to the Hardware Cabling electronic document topics or to the PDF on the SANtricity ES Storage Manager Installation DVD.



3. If you are changing the HIC type, attach the replacement HIC subplate. 4. Reattach the front bezel to the controller canister by reinserting the four screws.5. Reattach the bezel flex harness by gently lifting the latch on the ZIF socket, and inserting

the ribbon cable into the ZIF socket. Then push the ZIF socket closed.6. Reinstall the top cover on the controller canister.7. If the SFP transceivers were present, reinstall them.8. Remove the controller air blocker. 9. Slide the controller canister all the way into the controller-drive tray. Rotate the release

levers towards the center of the controller canister to lock that component into place.10. Reconnect all of the cables that were disconnected when you removed the controller

canister.

11. Look at the LEDs on the controller canister to make sure that the controller is rebooting correctly. The LEDs come on and go off intermittently for approximately 60 seconds (possibly longer). After this time, you are able to discover the controller by using the storage management software.

Depending on your version of HIC, you might receive an error message about a failed host I/O card. If this problem occurs, follow the instructions in the Recovery Guru.

12. Look at the Controller Service Action Required LED, and look at all of the controller-drive tray’s Service Action Required LEDs. Based on the LED status, perform one of these actions:– All of the Service Action Required LEDs are off, and the Array Management

Window indicates an Optimal statusGo to step 14.



Go to step 14.


14. Complete any remaining Recovery Guru procedures, if necessary.15. Using the LEDs and the storage management software, check the status of all of the trays

in the storage array.

NOTICE! If a HIC was added where none existed previously or if a different type of HIC was installed, additional system cabling and configuration might be necessary. Refer to the Hardware Cabling electronic document topics or to the PDF on the SANtricity ES Storage Manager Installation DVD.

NOTICE! If your storage array does not have an Optimal status, click the Recovery Guru toolbar button in the Array Management Window to determine if any other actions are required.
