RE: Disk Failure

Dare,

SPD stands for System Products Division, the folks within IBM who
originally designed the bus architecture.

Concurrent maintenance of cards and disks is fairly recent.  (My
recollection is that this was introduced with the V4R4 hardware
announcements and has been improving since then).  This is what allows
for replacing failed chunks of the system without bringing the entire
system down.  Older PCI-bus models would also have to be completely
powered off, so it's not unique to SPD.  No SPD-based CPU's system units
will have this feature however.
