You don't mention the OS level your system is at, that has some effect on
the answer.
Once a disk unit is marked as damaged, it cannot be removed as you are
suggesting, since that unit is part of the RAID configuration. About the
only "safe" way to do it is to replace the failed unit and rebuild it.
The only way to accomplish removing that damaged disk unit, is to stop RAID,
remove the drive from the ASP, remove the drive from the system, restart
RAID. Even on a small system (~3TB) that will take quite some time(meaning
most of a weekend to stop/start RAID). Also during that time you have no
disk protection of any kind. If you have bad cache batteries, then more
like a week to do it. In the end, real bad karma to try. Since I'm
convinced something will go wrong during that whole procedure, (it almost
always does) you will just wind up restoring to the full system save you
took just before starting any of this falderal. That will of course also
fix it since you would not be able to add that drive to the system.

Subject: disk damage help
Hi, I have a situation, a damaged disk, we cannot replace it at the moment,
can I remove that disk from the ASP and then remove it from the RAID ?.
Or do I have to go through the process of replacing and rebuilding it?
At another time I would change it and put it in the raid and the ASP again.
But at the moment I can't afford to damage another disk.
first of all, Thanks
