Product description DLm Release 3.5.0p5 is a patch release update of Release 3.5.0 of the EMC Disk Library for mainframe software. See the Disk Library for mainframe Version 3.5 Release Notes for DLm6000, DLm2000 and DLm1000 (EMC P/N 300-015-020).

Fixed problems

Virtuent fixes

Fixed in DLm 3.5.0p5 Change to file locking which avoids DLm463W messages while scripts

are running. (ARS 557109)

Fix RSA Lock that caused Virtuent to not be able to get keys from the DPM until it was restarted. Update the RSA client to version 2.7.1.12. Changed to retrieve the key again if getting a decryption key fails. (ARS 595302) NOTE: The version that rsakey reports will be 7.1.1.2 instead of 2.7.1.12.

Limit polling of back-end tape libraries for RO state to a default of once every 5 minutes. This was added to ease the load on DD storage. This value can be set on the command line (set TapelibPoll=xxx) or in the configuration (TapelibPoll xxx) where xxx is minutes and a value of zero disables the polling completely. (ARS 596978)

Firmware fix to clean up after an async status has been tossed.

Allow EFSMOVEFLR and EFSMOVEGR to be set in the configuration file (ARS 597469)

Fix UNQUIESCE TAPELIB directory file handle leak.

Fix streaming issue by sending a disable streaming packet to all adapters when any adapter transitions from streaming to non-streaming CCWs in order to keep both adapters in sync. Fix Firmware to not send chain broken at an inappropriate point during data streaming. (ARS 595172)

Added capability to SET GR on and off. Syntax is: SET GR=ON/OFF [DEV=devname] With no device specified, sets all devices at once. The Effect is immediate. If a tape is already being written, the new GR option is honored at the next GR sync point (for example at the end of that tape).

Fixed in DLm 3.5.0p4 Removed DLm300W message that printed from detection of spurious

asyncStatusSent messages.(ARS 593249, 592559)

Fixed incorrect sense data sent on a retried Sense CCW, which could result in "undetermined errors" following a unit check on some hosts. This may cause DLm301w halt I/O messages. (ARS 571206)


Virtuent fixes (continued) Fixed intermittent problem of paths going busy if the first streaming

write CCW was followed by a non-write CCW on a different path.(ARS 590471)

Added device name and VOLSER to messages DLm772E and Dlm771E. (ARS 589676)

Corrections and additions command help. Added PROTECTVOL1, WRITEVERIFY, DDWRITEVERIFY, TESTCOMPRESSEDDATA, AMDD, and FSALLOCATION to SET help. (ARS 590452)

Fixed incorrect result counts for an INIT command that had errors.(ARS 589960)

Fixed find command to not display duplicate entries for scratch tapes when a '*' wildcard was specified in the VOL= parameter.(ARS 589668)

Fixed in DLm 3.5.0p3 Made 068I message to be consistent for all versions of code.

Remove import/export check in trace logging that caused a malformed log entry.

Extended RSA reinitialization time.

Don't display message DLm243E that occurred when the QUERY LOCKS command polled a lock that was legally no longer in use. (ARS 587579)

Fixed message DLm773E to say "ENCRYPTKEY" rather than "KEY". Fixed QUERY CONFIG to not show a static key value when the device is not configured with an encryption key value, while an encrypted tape is being read. (ARS 587152)

Enhancement to AWSHEX to display the type of encryption (static, openssl, bsafe) for encrypted blocks.

Allow openssl-encrypted tapes to be appended to with BSAFE-encrypted blocks. (ARS 586262)

Fixed potential abend in SNMP.

Fixes timing window for async status getting new CCW before QLogic returns assigned xid. (ARS 576429)

Fixed equipment check on Write Tapemark if Guaranteed Replication is on and WriteVerify=DATA or CRC, and the tapemark is written in the LEOT area, of the tape, with messages "DLm423W: Device xxxx Volser xxxxxx READ FORWARD past end of data from block nnnnn" and "DLm419E: Device xxxx data read returned error" displayed (note no reference to a WTM error, but that's the CCW that gets the unit check on the host). (ARS 586658)

Clarify message DLm961 to show reason for the encryption incompatibility.

Do not terminate snmp in the event of failure. (ARS 0583692)

If the Test Compressed Data feature is set to CRYPT (the default), a block that compresses to a larger than original size and is encrypted will fail TCD with message DLm341E. (ARS 585612)


Virtuent fixes (continued) Ported change made in 5.01-6314 to accept the "M_volser" load

display as a mount request. (ARS 584999)

For consistency between virtual and physical tape devices, tapelib path value will always be displayed as 'DRIVE-<sn>'.

Fixed the problem where a SYSTEM RESET on a path caused streaming to be turned off on different path.

Corrected SNMP subsystem from failing on certain error messages. (ARS 583692)

Fixed bug where scratch volumes might be moved into filesystem had QUIESCE SCRATCH set. (ARS 577304)

Repeat DLm690E message once every 24 hours even if the usage percentage doesn't change.

No message was being displayed when a scratch mount bypassed a critically-full filesystem. (There was a debug level 2 message only.) Added messages DLm266W message for this event.

Allow control of the re-send lost async interrupt feature. Config with "ResendLostInterrupts YES/NO" and SET with ResendLostInterrupts=YES/NO. Default is YES. Also the time to wait to re-send is now configurable with ResendLostInterruptsSecs; default is still 15 seconds.

For SCSI tape drives, force assignment of decryption key when reading an encrypted tape when the device does not have an encryption key defined.

If, after sending the async status and getting asyncSent response, we do not see any read/write I/O at all on the requester path, and we see no read/write past labels on any other path, we re-send the async one time after 15 seconds. New message DLm321I informs that this happened. We do this only once per tape mount. The re-sending of presumed-lost async ready status is not performed for SCSI drives. (ARS 579716 and ARS 580473)

Added new message DLm179E informing that a filesystem that is mounted on the VTE as read-write is actually exported as read-only. Virtuent will treat the filesystem as read-only rather than read-write. (ARS 531414)

Fixed issue where VOLSER that is being moved on one VTE is reported as not found rather than busy on another. (ARS 576376)

Changed return code to be -5 for RUNWAIT timeout instead of -4. Changed message 556 to be and E level instead of W. (ARS 576366)

Check for change in mount hard option on the lock directory.

Fixed in DLm 3.5.0p2 Enable Physical Tape support for DLm1020. (ARS 569869)

Fix WriteVerify to only verify from low-write location when appending, instead of block/offset 0. (ARS 569196)


Virtuent fixes (continued) Added Write Verify History to Q+.(ARS 569559)

fix: MDL trap support was lost in code cleanup oversight (ARS 562570)

Fixed a Streaming Bug where the firmware could fail to send a ChainBroken message when it should if it received a Disable Streaming mode between a Status and Status Accept

Fix for ACL autofill mount failure, along with other potential unpredictable side effects (including abends), when ACLON specifies a 7 or 8 character synonym. (ARS 569527)

Report 890E message in response to "Query <MSG NUM>" when <MSG NUM> is not a defined message in the system. (ARS 556087)

Fix bug when checking for NFS mount failures, the 'c' in "can't" is lower case, we were checking for uppercase. Change the case, and perform case insensitive search. (ARS# 566140)

Accept abbreviation "QUERY LOCK" for "QUERY LOCKS" command.

Display the Volser Lock Directory message 256I as part of "QUERY LOCKS" results. (SR004076)

Added additional validation to parameters to the FIND VOLUME command. (ARS 565301)

Fix problem where letting TestCompressedData default to the CRYPT value resulted in no testCompressedData functionality being performed at all, even though a QUERY ALL displays "DLm068I: Testing of compressed data set CRYPT". Work around for field: either manually issue "set testCompressedData=CRYPT" or add "testCompresedData CRYPT" to configuration file.

Only allow KEYCLASS to be set if RSA license installed, and ENCRYPTKEY to be set if RSA license is not installed and ENCRYPTION (static key) license is installed. (ARS 564107)

Fixed bug where VOLSERLOCKDIR is defined in the configuration but because it is not accessible EFS is turned off; the new fixed behavior is that EFS remains ON with the lock directory set to broken which will disable only EFS moves.

Fixed seg fault caused by "set UNISYS" command issued without a "dev=". (ARS 560815)

Fixed AWSHEX failure to handle decompression of large blocks correctly. (SR004470)

Made changes to reporting terminology to achieve consistency with AWSLIST. (SR004471)

An empty scratch list is now perceived as "none available" instead of "no scratch list" during a scratch mount. (SR004533)

Disallow device base tape library path (i.e. /tapelib) to be QUIESCED. (ARS 558128)


Virtuent fixes (continued) Fixed a Watch dog timeout when ccw number = 0xFFFF during data

chaining (ARS 547953)

Added Enhancement to allow deferred encryption key setting (static and RSA). Setting will be deferred until the next unmount if a volume is mounted when the operator selects a new encryption key.(ARS 546094)

Check return code from stat command before searching for another device having the file open. May get incorrect match if stat'ing file that doesn't exist. Seen as new load display getting an indication that a scratch file exists, when the volser doesn't exist at all. (ARS 522504)

Fixed in DLm 3.5.0p2 but not previously documented Include updated flashupdt-1.9.70-21.i586.rpm package.

Do not display "421I: signaled end of volume to host" when end status is deferred, display only when status is actually sent.

Add protection for spurious asyncStatusSent messages. SR004575

Don't display error for read past EOT for import/export as that is

normal behavior.

Add new sendGoLive configuration parameter (yes/no) for standby

mode.

Changed statfmt to put spaces for mount record display instead of for

failed mount entries.

Add rotate of local and dr logging statistics file with new ROTATE LOCAL | DRLOG command within virtuent. Add rotate_local and rotate_drlog scripts to run rotate these files if the application is not running. Add processing of the rotate record to statfmt. Add --bin option to statfmt to make a binary version of a vstats file containing just the specified date range.

STREAMING is now a synonym for STREAMDATA in SET command.

Help says STREAMING now too. DLm063 now consistently says "Data

Streaming" instead of a few variations on that term.

Since the introduction of streaming, x'DB' was being accepted while in

supervisor state (i.e. mid-chain). Now it's accepted in supervisor state

when streaming, and rejected with command reject if not streaming

(as it was before streaming).

Bump the rsakey timeout from 32 seconds total to 2 minutes.

Fixed bug in help command text where "-01" displayed instead of the

three digit passed message number. (ARS 556087)

Align DLm068I help text to the documentation


Virtuent fixes (continued) Give Test Compressed Data its own new error message 343E instead

of piggy-backing on 341E.

Modified scsiadd to call "rescan-scsi-bus" if it exists on the system as it

is the current convention and avoids spewing on errors on the scan.

Fixed help text for messages 017, 104, and 111

Changed message 899I "Tape libraries have been locked by <task> for

nnn seconds" to new 905I message, and 900I "Tape libraries no longer

locked by <task>" to new 906I message.

Added to DLm900I message the state we're transitioning from and the

time that state was entered.

Corrected and expanded help text for MAS098I.

Added help text for new messages (these messages' text previously

used 899I in 900I along with the "has been in state" messages):

905I: Tape libraries have been locked by <task> for nnn seconds

906I: Tape libraries no longer locked by <task>

Removes the requirement for restarting the Virtuent application to

see newly added physical tape drives by having the 'show drive list'

rescan for new drives before displaying the list. Note: if Linux doesn't

know about a new physical tape drive then the operator will still have

to issue the 'scsiadd' command prior to showing the drive list.

On a streaming write, do unit check on first CRC error, no retries. Corrected CRC error handling bug for data chained writes introduced

in r11702. Since r11702, if an error occurred in any segment other

than the last one it didn't get reported to the host.

Changes to statfmt utility program:

Fix devname printing in TXT routine.

Add printing new path field in TXT.

Fix structure references in convertMountFields.

Modified Virtuent application to save full Directory name in all stats

mount and unmount records. Modified Virtuent application to save

encrypt flag in stats unmount records. Modified statfmt to read the

new records.

For statfmt program, added more checking when trying to find a good

record after corruption was detected.


Virtuent fixes (continued) Fixed channel CRC error handling. It was previously looping forever on

retries. Now it works properly by retrying ten times then returning

unit check (with Bus-Out Check sense) on the eleventh consecutive

CRC error. Also added a configuration/SET option to choose unit check

on first occurrence instead of any retries: CRCERROR=RETRY or

CRCERROR=UC; default is RETRY. New message DLm164I displays the

CRCERROR setting in QUERY ALL, and when SET or configured.

Added the full path of the tape in the 899I message.

Restart the rsakey process more carefully. Don't use a null encryption

key (such as after key-server failure). A write on a drive that supports

encryption will now fail with a unit check (with equipment check

sense) if a key cannot be obtained, rather than writing with a null key.

Correct SET SIZE= help text. The minimum is 40M.

Added help text for the new SET LEOT parameter.

Fixed bug that allowed tapes to be moved into SCRATCH QUIESCED

tape libraries.

Correct stale state codes in tape library structure. This caused the

'idle' state to be displayed as 01000831.

Fixed in DLm 3.5.0p1 The fix to make Test Compressed Data correctly default to ON (CRYPT)

(as opposed to OFF while telling you it was ON (CRYPT)).

ACP fixes

Fixed in DLm 3.5.0p4 The ha_status confused an IP addr with a bcast addr causing 994E dial

homes. This only happens when the IP addr string is a subset of the bcast addr (ARS 590687).

Fixed in DLm 3.5.0p2 Fix bug where we were sending dlmdrtools messages to both

/var/log/messages and /var/log/dlmtools/dlmdrlog.

Fix for ARS 548078 where the DLm.html homepage was not being copied in for DLm6000 and DLm2000 systems being brought up.

DLm Console fixes

Fixed in DLm 3.5.0p5 Virtuent is not automatically restarted with a storage only change.

Add non-disruptive storage changes.

Fixes to improve IE8 compatability (ARS 596981)


DLm Console fixes (continued) Fix to allow a change of a freeform path (e.g. drive-nnnnnnnnnnnn)

back to /tapelib (ARS 596981)

When upgrading from 3.3.x to 3.5.0 be tolerant of the missing extra_params section of the 3.3.x configuration file (ARS 594510)

Stop limiting the number of log files to 7, just respect the number of days to collect (ARS 594724)

Fixed in DLm 3.5.0p3 Fix fstab read hang with missing #END Records

Don't warn when .CLASS0 is changed to no class

Don't try and umount /.

Fix ARS 582346: when a storage device is not found in the showmount export list, log the list to logAll for better diagnostics.

Fix bug where a postgres index got corrupted, causing the DB to get really slow.

Fixed in DLm 3.5.0p2 ARS 556517, Add /backup to the DD export list when

/data/col1/backup is exported, for any export using /data/col1/backup.

Fix for ARS 573597. Cron must be restarted when the timezone changes.

Change btilog path back to /var/bti/log. This appears to be an inadvertent change when r11654 and r11655 were made.

Merge from 4.0: Fix cosmetic bug where IE displays the "no performance data" message in a vertical column.

Merge from 4.0: Fix problem where capacity page fails to load in IE 9 with "Unable to get value of the property 'initElement'".

Merge from 4.0: Fix AR 560975: After DLm Console install vte:/etc/resolv.conf not updated with DNS values.

Fix problem where old Firefox gets confused by dashes in HTML comments.

Add checks to allow installation on SLES 10 only. Can be overridden by touching /opt/dlmspecial.

Merge from 4.0: Fix AR 542287 No output from Load command [Webcon virtual Command prompt]

Fix AR 555756: Logging in with unsupported browser gives error msg mentioning "Webconsole" rather than "DLmConsole"

Merge from 4.0 tree: Fix AR 557141: Storage Location for dlm_lock_fs cannot be modified after initial save

Remove flashupdt usage from getLogs. It occasionally hard hangs a VTE requiring POR.

Merge from 3.05: Fix bugzilla #776: Webconsole log file display doesn't work.

Port r11423 from 3.04: Fix ARS 543702: the output format of /opt/webconsole/scripts/list_storage has changed


Virtuent help documentation update This section includes help documentation for the following Virtuent “set” commands and/or “additional parameters” options. The following have not yet made it into the DLm 3.5 User’s Guide or Virtuent online help:

PROTECTVOL1 WRITEVERIFY DDWRITEVERIFY TESTCOMPRESSEDDATA AMDD FSALLOCATION

PROTECTVOL1=ON/OFF Is a feature that prevents the accidental overwriting of a VOL1 label. Any attempt to overwrite a VOL1 label with data or a tapemark, once data has been written elsewhere on the tape, will be blocked with a write-protect error, with message DLm920E displayed. Message DLm921I will also be displayed each time, as a reminder that the feature can be turned off if required. This feature

is on by default.

WRITEVERIFY=[ON/OFF/CRC/DATA/HEADERS] DDWRITEVERIFY=[ON/OFF/CRC/DATA/HEADERS] The WRITEVERIFY options control the degree of data verification Virtuent performs following writing of data to the tape library.

CRC reads the data from the disk, checks the disk CRC, but doesn't

decrypt or decompress the data. This is the default option when ON is selected.

ON is synonymous with CRC. After writes, the data will be read back

and checked against the CRC generated when it was written.

OFF turns off all read-back verification of data written to the tape

library.

DATA configures the write verification feature to perform full

verification of the data blocks. Full verification entails reading, checking the data against the CRC generated when it was written, decrypting, decompressing and checking the CRC of the block against the original CRC written by the host.

HEADERS configures the write verification feature to only check the

AWS headers if each block. When HEADERS is set, the full data blocks are not read or checked.

DDWRITEVERIFY is used to control the operations on Data Domain back ends.


Virtuent device options – Help documentation (continued) TESTCOMPRESSEDDATA=[ON|OFF|CRYPT] This option controls the integrity check of data after compression. If this

option is set to CRYPT (the default), data compressed by Virtuent is

decompressed, and if encrypted it is also decrypted, then compared to the original data from the host before it is written to the virtual tape library. If this

option is set to ON, data compressed by Virtuent is decompressed but the test

but does not perform data decryption. In either case above, if a discrepancy is found, an error is returned to the Host's write command. If the Test

Compressed Data feature is turned OFF, no extra integrity check is performed

after compression before writing the data to the tape library.

AMDD=[ON|OFF] This option turns on or off the Assisted Mainframe De-Duplication (AMDD) feature that modifies data written by the host for more efficient de-duplication. AMDD is on by default for all Data Domain storage, and has no effect on non-Data Domain storage. EMC recommends that the AMDD feature be left on, for improved de-duplication of data written by the host to a Data Domain. This is a global parameter and it affects all virtual devices on this VTE. Setting the AMDD feature on or off only affects writing of data; data previously written with AMDD can be read even if AMDD=OFF.

FSALLOCATION=[RR|SPACE] This option sets the method for choosing a filesystem for a scratch tape mount. The default is RR (Round Robin); Virtuent cycles to the least-frequently used eligible filesystem to fulfill a scratch tape mount request. RR is the recommended setting as it tends to allocate scratch tapes evenly from all the filesystems over time. The SPACE setting instructs Virtuent to use the filesystem with the most available free space, and is not recommended as it will tend to allocate scratch tapes from a limited number of filesystems rather than spreading them out more evenly.
