Chapter 8 HA Functions | > 8.5 Recovering Shared Disk Faults |
If the shared disk where director data files are located fails, replace the disk, and then recover the director data files on the active server.
The following diagram shows the procedure for recovering director data files when MSCS is used.
Before recovering director data files, stop all applications to prevent data searches and updates from occurring.
Check the resource status using the cluster administrator.
Vary any online Shunsaku resources offline.
Replace the shared disk where the fault has occurred and restore its settings.
Vary the shared disk resource online using the cluster administrator.
Make sure that the status of the resource is online.
Create a folder for storing director data files on the file system on the shared disk.
Vary Shunsaku resources online using the cluster administrator, and then start Shunsaku.
Once Shunsaku has started, make sure that the status of all resources is online.
Recover the director data files by executing the shundrecover command from the Command Prompt on the active director server.
shundrecover -s director-identifier -b |
copy /b backup-data director-data-file-folder |
shundrecover -s director-identifier -e |
This will cause Shunsaku to restore the director data files to their latest state by using the operation log files.
An example is shown below.
shundrecover -s shund1 -b copy /b Z:\backup\shund1\* Y:\shunsk\shund1 shundrecover -s shund1 -e |
These commands will complete the restoration of the director data files, allowing jobs to recommence.
