Recovering from SRC 6xxx 7052

You are receiving this message because the counter that tracks the number of write operations to this drive has reached 75% of its maximum value.

This counter is used to determine if data on the drive is current with data within input/output adapter (IOA) memory. Because this counter is large, it is not necessary to stop compression for this drive immediately, but you should do so during your next scheduled maintenance. If this counter wraps, data can be lost.

To stop compression and restart compression on the disk drive to reset the write count, perform the following tasks:

  1. Perform a manual mode initial program load (IPL) to dedicated service tools (DST).
  2. To find the resource name of the disk drive with the problem, perform the following tasks:
    1. Select the Use dedicated service tools option.
    2. Select the Start a service tool option.
    3. Select the Hardware service manager option.
    4. Select the Work with service action log option.
    5. Select the time frame of the problem.
    6. Record the resource name that is associated with the 6xxx 7052 entry in the system reference code (SRC) column.
  3. Remove the disk unit from the auxiliary storage pool (ASP).
  4. Stop compression on the disk unit.
  5. Start compression on the disk unit.
  6. Add the disk drive back to the ASP from which it was removed.

This ends the procedure.
