Re: Catastrophic disk failure

Thanks, everyone.

I think I'm hosed on this. RAID is not enabled and the drive is failed. Replacing the drive means whatever was on the failed drive is gone, including whatever part of the OS it's still trying to execute in the IPL. So, my system is corrupted.
So, we'll have to de-configure and remove the bad drive, insert the new drive, configure it, enable RAID and load the entire system and libraries from our system save tape.
One last question: if my system save is from a server which did NOT have RAID enabled, will my system be restored as RAID enabled?  I mean, what's on my tape does not have the extra parity bit, so when the system is restored will the restore put it back with a parity bit because the server itself is now RAID enabled? Am I making sense?

Best Regards,

Thomas Garvey

Why would IBM deliver a box with RAID capability and not configure it?

Misunderstanding? Or maybe there was a RAID5-Setup-Specify not being satisfied with the order? Or it’s really a customer thing, but I doubt it.

Is it possible RAID5 was our responsibility?

Honestly: Clarify with your dealer. He should be able to tell.

Can it be set up AFTER the OS and Licensed software is installed by IBM?

Yes, as long as there’s enough free space: You’ll lose one disk worth of capacity to the checksums of RAID5.
