Last Thursday evening our IBM I POWER6 on V5R4M5 became unavailable.
QINTER green screen users lost connection.
Web apps went offline.

The HMC green screen in QCTL remained up for just a few minutes more.
Used HMC to diagnose with IBM's guidance.

Based on messages shown at end of this message,
IBM tech brought a SCSI DASD controller card and disk drive to our
site.

He replaced DASD controller card but could not IPL from disk, only from
CD.
Put the old DASD controller card in and replaced failed disk unit.
IPLed successfully and our users were able to sign on.

(...and way too much other information)
