Recovering from an MSDP storage server disk failure
If recovery mechanisms do not protect the disk on which the NetBackup software resides, the deduplication storage server configuration is lost if the disk fails. This topic describes how to recover from a system disk or program disk failure where the disk was not backed up.
Note:
This procedure describes recovery of the disk on which the NetBackup media server software resides not the disk on which the deduplicated data resides. The disk may or may not be the system boot disk.
After recovery, your NetBackup deduplication environment should function normally. Any valid backup images on the deduplication storage should be available for restores.
Veritas recommends that you use NetBackup to protect the deduplication storage server system or program disks. You then can use NetBackup to restore that media server if the disk on which NetBackup resides fails and you have to replace it.
Table: Process to recover from media server disk failure
Step | Task | Procedure |
|---|---|---|
Step 1 | Replace the disk. | If the disk is a system boot disk, also install the operating system. See the hardware vendor and operating system documentation. |
Step 2 | Mount the storage. | Ensure that the storage and database are mounted at the same locations. See the storage vendor's documentation. |
Step 3 | Install and license the NetBackup media server software. |
See NetBackup Installation Guide for UNIX and Windows: |
Step 4 | Delete the deduplication host configuration file | Each load balancing server contains a deduplication host configuration file. If you use load balancing servers, delete the deduplication host configuration file from those servers. |
Step 5 | Delete the credentials on deduplication servers | If you have load balancing servers, delete the NetBackup Deduplication Engine credentials on those media servers. |
Step 6 | Add the credentials to the storage server | Add the NetBackup Deduplication Engine credentials to the storage server. |
Step 7 | Get a configuration file template | If you did not save a storage server configuration file before the disk failure, get a template configuration file. |
Step 8 | Edit the configuration file | |
Step 9 | Configure the storage server | Configure the storage server by uploading the configuration from the file you edited. |
Step 10 | Add load balancing servers | If you use load balancing servers in your environment, add them to your configuration. |
