Tivoli Storage Manager for NetWare Backup-Archive Client Installation and User's Guide

Example 1: Loss of a Non-SYS Volume

NDS information is stored only on the SYS volume. Therefore, if you experience a hard disk failure on a non-SYS volume, you do not have to modify or restore any part of the NDS tree. You only need to restore file system data (including file and trustee data).

To restore a non-SYS volume after a hard disk failure:

  1. Do not delete the Volume object for the failed volume from the NDS tree. In this situation, you can leave the Volume object in the NDS tree to preserve any references that other objects may have to the failed volume. If the Volume object is deleted, you will need to replace any objects that have references to the failed volume to reestablish the references correctly.
  2. Bring down the server and replace the failed hard disk(s).
  3. Bring the server up and recreate the volume using the NWCONFIG.NLM utility. At the server console, type
    load nwconfig
    

    and create a NetWare partition on the new disk, thus redefining the volume to NetWare. NetWare will (re)place the Volume object in the NDS tree.

    Note:
    Ensure that utilities such as DSREPAIR.NLM or DSMAINT.NLM are not running when you load NWCONFIG.NLM to ensure that the Volume object is (re)placed in the NDS properly.
  4. Remount the volume using NWCONFIG.NLM.
  5. Load the necessary SMS target service agents. At the target NetWare server console type:
    load tsands
    load tsa500 (NetWare 5)  or
    load tsa600 (NetWare 6)
    
  6. Restore the volume(s) using Tivoli Storage Manager. Enter the following NetWare console command for each volume you want to restore:
    load dsmc restore vol1:\* -subdir=yes -replace=all -volinfo
    

    Where vol1: is the name of the failed volume.
