Greetings,

I have a rackmount RS/6000 running 4.3.3 that I picked up support on
recently. It has 3 pairs of mirrored disks, and recently hdisk1 failed,
which is the mirror of hdisk0 in vgroot. I checked Google and the
examples of replacing a failed mirrored drive all showed the drive with
status of missing. For me, hdisk1 showed as status of removed. I was
able to unmirror vgroot, remove stale lv refs to hdisk1 reduce the vg
and delete hdisk1 with no problem. I now have a standalone system disk,
hdisk0. I pulled and replaced hdisk1 and ran cfgmgr to detect the new
drive. No new disks were detected. I have two spare 18gb disks, neither
were detected and lspv shows the same disks as always, 0, 2-5, and the
three raid arrays.

Do I possible have another problem in the scsi controller that might
have caused the status of the failed hdisk1 to show removed instead of
status missing? Anything else I could check that might point me in the
right direction?

Thanks in advance for any assistance.
