Scsi Errors.

[Justin Bennett]

Its a new box, It's less than one week old, Its got 6 drives, 3 logical 
(mirrored) 2 scsi raid (adaptec 2120s) controllers. I put this in last 
wednesnight, so the drives are all but new.. I did have a defective spot 
found on one of the drives since we put it live. Adaptec has a raid 
manager command line program and it gives you drive details.

AAC0> disk list
Executing: disk list

C:ID:L  Device Type     Blocks    Bytes/Block Usage            Shared Rate
------  --------------  --------- ----------- ---------------- ------ ----
0:00:0   Disk            71687372  512         Initialized      NO     320
0:01:0   Disk            71687372  512         Initialized      NO     320

0:03:0   Disk            143374744 512         Initialized      NO     320

AAC0> disk show defects (0:3:0)
Executing: disk show defects (BUS=0,ID=3,LUN=0)

Number of PRIMARY defects on drive: 921

Number of GROWN defects on drive: 1
Defect 1 at cylinder 928, head 1, sector 855



So at some point (possibly lat night) it found a defect on that drive, 
all the others the grown defects are 0.
