Restoring CommCell Operations on the CommServe Host

Use the CommServe Disaster Recovery Tool to perform various tasks relating to the restore of CommServe databases.

Note: If you are using the tool for staging the CommServe database for troubleshooting purposes, see Staging the CommServe Database Using Disaster Recovery Tool.

Before You Begin

  • Use SnapProtect Process Manager to stop all services on the CommServe host. See Stopping a Service
  • If changing license, obtain a new license from your software account manager or support.
  • Ensure that the correct version of the disaster recovery backup files (SET_XXX folder), that you want to restore, is available on the CommServe. You can find the disaster recovery backup Job ID and the time when the backup job completed in the version.txt file in the SET_XXX folder. Note that Disaster Recovery Backup files (.dmp) are portable between CommServe computers running Microsoft Windows Server 32-bit and x64 edition operating systems.
    • If you have the disaster recovery backup files in the network location, copy the files to the local disk on the CommServe host.
    • If you have the disaster recovery backup files on a disk or tape media, see Retrieving Disaster Recovery Backup from Media.

      • Under CommServe Physical Nodes, type the names of the physical CommServe nodes as they appear in the Microsoft Failover Cluster Manager.

        Do not copy and paste the physical node name from the registry, or add the characters "_node" to the node name. The characters "_node" are automatically added to the physical node name during the database restore operation.

      • Configure the bSendUpdateStatusToCS additional setting to send the update status to the CommServe database.
  4. Click OK to execute the operation.

When finished, use Process Manager to start All Services on the CommServe host.

Result

After the DR restore, you will notice a considerable increase in the job ID for new jobs. This increase is added to avoid conflicts with job IDs referenced in the deduplication databases (DDBs) when the DDBs are resynchronized.
