DISASTER RECOVERY FOR HP NNM PLATFORM

Backup of NNM Platform HP NNM platform consists of 5 databases residing on different servers. These 5 databases have to be

backed up frequently along with NNMi configuration, NNMi topology and NNMi Events. Figure-1 shows

databases residing on different servers.

Figure-1

Backup of Server 1 This server consists of Postgres database supporting NNMi Platform. Postgres DB stores data related to

the NNM configuration, events and topology.

Backup of NNMI configuration, events, topology and Postgres DB

Things to backup:

I. Configuration

II. Topology

III. Events

IV. Database

Back up All Data Periodically (Online backup)

Command:

nnmbackup.ovpl -force -type online -scope all -archive \ -target nnmi_backup\periodic

force: This option is used to back up nnm while running

type: This option is to specify if it is online backup or offline backup

scope: This is used to specify if scope of bacup. (i.e. Topology, event, config or all)

archive: This option is used to backup archive files.

Target: Specify target directory.

Backup of Server 2 This server consists of SYBASE IQ database supporting NNMi Platform. SYBASE IQ DB stores device data

collected by NNM and its iSPI’s.

Backup of Sybase Database:

Command:

backup.ovpl –b <backup directory path>

Note: If no backup flags (-c, -d, -f) are given then all default to true.

SYNOPSIS

backup.ovpl [-h] [-b dir] [-c] [-d] [-f]

where:

-h displays this text

-b dir specifies backup directory

Note: If this directory exists it is removed.

-c backup contentstore

-d backup database

-f backup files

-v verbose mode

Note: If no backup flags (-c, -d, -f) are given then all default to true

Backup of Server 3 This server consists of SYBASE database for OVPI. It stores the data collected from NNMi. This database

is backed up every day at 7:59PM and stored in E:\Sybase_Backups\current\ folder. This backup can be

copied and to the backup location.

Restore of the entire Module 1> Restore of NNMI

a> Same system Restore

The following items must not have changed between the time of the backup and time to

restore:

NNMi version(including any patches)

Operating system type and version

Character set (language)

Hostname

Domain

Command to restore:

nnmrestore.ovpl -force -lic \-source nnmi_backups\periodic\newest_backup

b> Different System Restore

The following items must be identical to the old system

NNMi version (including any patches)

Operating system type and version

Character set

The following items can differ between the two systems:

Hostname

Domain

Command to restore:

nnmrestore.ovpl -force \ -source nnmi_backups\periodic\newest_backup

Note: when performing restore on different system update the license.

2> Restore of SYBASE IQ

a) Same system Restore

The following items must not have changed between the time of the backup and time to

restore:

NNMi version(including any patches)

Operating system type and version

Character set (language)

Hostname

Domain

Command to restore:

Restore.ovpl -b <backup file>

SYNOPSIS

restore.ovpl [-h] [-b file] [-l] [-v] [-s]

where:

-h displays this text

-b file specifies backup file

-l lists file content without restoring

-v verbose (default)

-s silent

b) Different System Restore

The following items must be identical to the old system

NNMi version (including any patches)

Operating system type and version

Character set

The following items can differ between the two systems:

Hostname

Domain

Command to restore:

restore.ovpl [-h] [-b file] [-l] [-v] [-s]

Note: when performing restore on different system update the license.

3> Restore of OVPI

Install OVPI and update the patches and restore the database as mentioned in the

PerVigil_PVLadmin_v4.3_PVLbackup_Sybase_UsersGuide.pdf document stored in

\\ffd-bkup-01\IS Users Group\HP NNM\OVPI\Pervigil_Installs\

PVLInstalls\Backup_and_Monitoring\ PerVigil_PVLadmin_v4.3 .

Updating of license (Required if different system restore)

Go to http://www.webware.hp.com

Click Manage Licenses.

Log in; then obtain your new license key by following the procedure to complete the

move process

Configure the DNS servers to recognize the new IP address of the NNMi management

server.
