Drive [1,3] on the A1000 array failed on 9/13/2003 and the host spare [1,0] kicked in. The replacement drive (Seagate) arrived on Friday and I installed it first thing this morning. The array rebuilt itself and is currently back to normal operation.

Drive replacement on these things is simple: snap out the old, snap in the new. It doesn't have to be powered down or brought into any kind of standby mode.

Testing indicates that future work for these arrays may be battery replacement.
