In a single-server network, the loss of the SYS volume implies the loss of
the entire NDS. To restore the server, perform the following
steps:
- Replace the failed hard disk(s).
- Reinstall the NetWare OS and NDS on the server. This step replaces
the Server and Volume object(s). Using the NWCONFIG.NLM utility
on NetWare, note the following precautions:
- Use the same server name in the install.
- Use the same admin parent container and password as the last NDS
backup.
- Ensure all hard disk partitions are at least as large as they were on the
failed server.
- Use the same volume names as on the failed server.
This step replaces the Server and Volume object(s).
- Ensure that the NetWare OS has the correct patches for Tivoli Storage
Manager to function properly. Refer to the
clientreadme.1st file for more information about
dependencies on NetWare OS patches.
- If the server had volumes other then SYS, and these volumes were not
affected by the failure, run DSREPAIR to purge the file system of
invalid trustees on those volumes. This step cleans-up the volume
directory entry tables (DET) and file entry tables (FET) so that the trustee
assignments can be restored correctly. At the server console, LOAD
DSREPAIR and choose the Unattended Full Repair option.
(This automatically purges invalid trustee assignments).
- Install Tivoli Storage Manager and reestablish the communications
protocol. Use the NWCONFIG.NLM utility to reinstall the Tivoli
Storage Manager code on the NetWare server. Reconfigure the
communications protocol so that the Tivoli Storage Manager client can
communicate with the Tivoli Storage Manager server.
- 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)
- Restore the entire NDS tree from Tivoli Storage Manager.
Use the following command at the NetWare server console:
load dsmc restore directory -replace=yes
The -replace=yes option is required to ensure that
place-holders created by the restore process are properly replaced by real NDS
objects.
- Restore the volume(s) using Tivoli Storage Manager. Use the
following NetWare console command for each volume you want to restore:
load dsmc restore sys:\* -subdir=yes -replace=all -volinfo
Where sys: is the name of the failed volume.
- Verify restoration of the NDS, file data and trustee data.
