8.5.1 Recovery Procedure for Director Data Files (MSCS)

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.

1. Check the status of resources.

   Check the resource status using the cluster administrator.

   Vary any online Shunsaku resources offline.

2. Replace the shared disk.

   Replace the shared disk where the fault has occurred and restore its settings.

3. Activate the shared disk.

   Vary the shared disk resource online using the cluster administrator.

   Make sure that the status of the resource is online.

4. Create an area for storing director data files.

   Create a folder for storing director data files on the file system on the shared disk.

5. Ensure that all applications are stopped, then activate Shunsaku resources.

   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.

6. Recover the director data files.

   Recover the director data files by executing the shundrecover command from the Command Prompt on the active director server.

   1. Make a recovery start declaration by executing the shundrecover command with the -b option specified.

      shundrecover -s director-identifier -b

   2. Restore the backup data for the director data files to the director data file folder using the copy function provided by the operating system.

      copy /b  backup-data  director-data-file-folder

   3. Make a recovery end declaration by executing the shundrecover command with the -e option specified.

      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.

   • director-identifier: "shund1"
   • backup-data: "Z:\backup\shund1\"
   • director-data-file-folder: "Y:\shunsk\shund1"

   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.
