Re: Perhaps their time has come.....

In my experience 'it depends'. Yes if you get the A600 SRC it's waiting to come back. This can occur with virtual storage in a number of ways and I've seen customers pull power from the 'right side' of 270 and 810 machines thus silencing up to 12 drives. Restore power and they come back. Last year at COMMON we popped a breaker and dropped 24 drives in an EXP24. After power was restored all was well again.

But if the controller says NO then no amount of arguing will make it change its mind. Kinda like Mom!

Weird,

I had somebody pull the wrong drive on a 520 and instead of borking the
entire system it just said a6000255, it surprised me when they put the
drive back in and lo and behold it came back without problems. Maybe it
depends on the controller whether it says "that's it i'm done" or it
reports to the OS inability to work with those drives?

Yep and they were not interested. HOWEVER they are now a customer of

The other is a global corporation that you would know at least by their
products as there is a better than average chance you have that in your
home or even on your person. They have an operations desk staffed 24x7 with
system consoles available to all POWER Systems. But to them these are the
ugly step children because they have been migrating to Windows since 1997.
(They're almost there!) The only thing left on POWER is receiving,
inventory, shipping, and EDI. :-)

To be fair they HAVE had some bad luck as well. One complete system outage
due to a tech (NOT IBM) pulling not the dead drive but the one next to it.
They also had a cache battery fail (not age out) on a Power5 520 internal
RAID card. This occurred at the same point where they had a drive fail and
in that debacle sufficient data for at least one other drive was lost
causing the system to die. IBM Was on site for this one and near as we can
tell it was all murphy on this one.

But remember that these RAID cards are getting as old as the drives! Also
remember batteries aren't perfect and back then redundant cache was an
option but not on all cards.

Keeping 'free' old hardware around just isn't really free!

Have they thought about some sort of Managed System Services by you to

weekly report that all disks are ok, both power supplies are running good
and no critical system situations exist?
Perhaps with the usual disclaimer at the bottom:
Based on the following:
- The age of this hardware, including, but not limited to, the number of
rotations on the drives,
- The age of this OS and the numerous security patches that have arrived
since
I recommend an upgrade of both hardware and software be evaluated.
