so far we've had zero issues with the Power 6 hardware.


Thanks,

Re: Power6 1 core RAID enabler hardware reliability

Some customer Power 6 systems this time last year had problems with
these, but haven't seen it lately. Every one was running RAID in the
CEC and required the card to be replaced, although if memory serves,
none of them crashed or suffered any degraded performance while
waiting for an outage opportunity to replace.

Played the PTF game with those as well, no help.

Hi All,

How many here are running Power 6 machines and have had hardware
reliability problems with the Power 6 machines?

We have roughly 25 9407-M15 and 8304-E4A deployed at various
customers, and by now we're at three system failures related to the
RAID controller - one of these was 3 days downtime, even though the
machine had SBD IOR. From what i can gather, the machines just running
mirroring with no RAID enabler cards don't have issues.

Currently we have an issue were the machine isn't down, but sending
error reports to IBM every 5 minutes, and performance is awful (though
the cache battery isn't marked as failed). IBM had us install PTFs
last night, which didn't help, and today i've installed another batch
of PTFs which didn't seem to help either.

Does anyone else here have similar issues?

Regards,

Lukas Beeler
