If you need to run ICKDSF on an S-VOL, you must change the status of the S-VOL to unpaired to allow write access. The pair must then be restarted.

  1. You can stop write I/Os to the P-VOL while the S-VOL is being repaired. To do this, split the pair from the primary system, using the raidcom modify remote_copy_pair command with the -operation split option and the -pvol_write disable option. You can also use the CSUSPEND TSO command.
  2. On the secondary system, select the S-VOL to be repaired, and then delete the pair. You can use the CRECOVER command.
  3. If necessary, change the S-VOL VOLSER to avoid problems due to duplicate VOLSERs.
  4. Vary the S-VOL online, and run ICKDSF to repair the S-VOL. When the volume repairs are complete, vary the S-VOL offline.
  5. On the primary storage system, select the P-VOL, and then delete the pair.
  6. Resynchronize the pair.
    You can also use the CESTPAIR TSO command to resynchronize the pair.
