Re: lpar processor allocation - find disk cache failure

["Jim Franz" <franz400@xxxxxxxxxxxx>]

I found these 2 messages that show up in QSYSOPR message queue
after an ipl. Not sure which controller card - not authorized to hardware
resources.
The WRKDSKSTS screen, then F11 shows each drive in status "DEGRADED".
Help text on that column says "hardware failure" and decreasing performance.
