HCP902W System recovery failure; fatal I/O error

Explanation
During system initialization,
an unrecoverable input/output
error occurred on the volume containing checkpoint data.

On a second-level system, this could occur if the checkpoint
or warm start volume is a minidisk, and you have defined the
SYSCKP or SYSWRM area on cylinders or pages
that do not exist on
the minidisk.

System action
The system enters a disabled wait state (wait state code = 902).

Operator response
Re-IPL the system.
If the error recurs, move the failing volume,
if possible, to another drive and retry the IPL.

The volume containing the checkpoint data is defined on the
SYSCKP parameter of the SYSRES macro in HCPSYS.

The volume containing the warmstart data is defined on the
SYSWRM parameter of the SYSRES macro.

If this is a second-level system, enter QUERY VIRTUAL vdev
for the checkpoint and warm start devices.
Verify that the
SYSWRM and SYSCKP cylinders or pages
exist on the device, and change them if
necessary.

If the problem
persists, take a stand-alone dump and contact your IBM Support Center
personnel for assistance.
