Details: We have a rack which contains our TSM AIX server along with a CISCO SAN Director. The rack has 4 power circuits. All equipment had dual power supplies, however - due to a human oversight - two of the RIO drawers had their redundant power supplies plugged into the same circuit. I know - a preventable error, but nonetheless, this resulted in log corruption that would have caused us much more grief had we not had the mirror copy. A power supply in the SAN Director blew, tripping the circuit that also had both redundant power supplies in the RIO drawer, taking down our AIX server hard.
Amen. There are also those computer room managers who go to Radio Shack and buy consumer power strips for the equipment in the racks...strips which always have a rocker switch on them. The inevitable, dire results are predictable. And even after the "accident", they leave the same power strips in place. Richard Sims
