RAID rebuild failed (PE2650)
I have (3) 36GB hard drives in a RAID5 configuration. Yesterday the first drive failed.
aacraid:Battery charge is now OK
aacraid:ID(0:00:0); Selection Timeout [command:0x2a]
aacraid:ID(0:00:0) - IO failed, Cmd[0x2a]
aacraid:ID(0:00:0); Aborted Command [command:0x2a]
aacraid:ID(0:00:0) - IO failed, Cmd[0x2a]
aacraid:ID(0:00:0) - IO failed, Cmd[0x28]
aacraid:RAID5 Container 0 Drive 0:0:0 Failure
aacraid:RAID5 Failover Container 0 No Failover Assigned
aacraid:Drive 0:0:0 returning error
There's no more 36GB drives available, so we have a 73GB hard drive shipped. The bad drive is removed and the new drive is installed. The array begins to rebuild itself automatically.
aacraid:Container 0 started REBUILD task on drive 0:0:0
The last time I checked it was almost reaching 40%, and then at some point it failed with this message.
aacraid:ID(0:01:0); Error Event [command:0x28]
aacraid:ID(0:01:0); Medium Error [k:0x3,c:0x11,q:0x1]
aacraid:ID(0:01:0); Read Retries Exhausted
aacraid:Container 0 failed REBUILD task: I/O error - drive 0:1:0 failed
0:00:0 is the hard drive that failed and 0:01:0 gives me an I/O error on the rebuild. What's going on and how do I recover?

Looks like there is a double fault. You could attempt to attach the drives to a SCSI controller and perform a media verify on ID 1. This will attempt to remap any bad blocks and if it is successful, you should then be able to rebuild ID 0 into the array. If it is not able to remap the bad blocks, then most likely you are looking at backing up data, deleting the array, replacing ID 1, recreating the array, reinstalling and restoring from backup.
