death of a mirror/raid disk is something you want to know about.

those Digital StorageWorks raid arrays were something, once
you had them set up.  i had disks dying every month but the array
would pick a free disk and just continue.

iirc, the RZ-2[89]'s were incredibly unreliable.  good thing i had
them in mirrors or raid 5.

the interface was a bit VMS-ey, but it walked all over those horrible
EMC2 fiber channel horrors ...
