Dedicated recovery of local load source – Local system is still functional

To recover from a local load source failure that uses dedicated maintenance when the local system unit and site are functional, follow these steps.

Note: If the input/output processor (IOP) that controls the load source supports 520 or 522 byte sector disk units, then you can move the remote load source disk units to it.
  1. Power off the system.
  2. Repair or replace the broken load source.
  3. Install the Licensed Internal Code on the repaired/replaced load source.
    After the install completes, the system will automatically initial program load (IPL) to dedicated service tools (DST). When the system reaches DST, all disk units and the system disk configuration will be missing.
    Note: Press F3 to go to DST and perform the remote load source recovery actions. Do not press F10 to accept the New Disk Configuration warning. If you do, you must restart the dedicated recovery from remote disk at Step 2 above.
  4. Use the Recover Mirrored Load Source function to recover the disk configuration and data.
    When recovery is complete, the system will re-IPL automatically.
