Verifying, diagnosing, and maintaining the system6–12
7. Verify that each of the physical disks is operational by entering the following command:
=> pd all show
MSA20 at 01
array A
physicaldrive 1:1 (box 1:bay 1, SATA, 250 GB, OK)
physicaldrive 1:2 (box 1:bay 2, SATA, 250 GB, OK)
physicaldrive 1:3 (box 1:bay 3, SATA, 250 GB, OK)
physicaldrive 1:4 (box 1:bay 4, SATA, 250 GB, OK)
physicaldrive 1:5 (box 1:bay 5, SATA, 250 GB, OK)
physicaldrive 1:6 (box 1:bay 6, SATA, 250 GB, OK)
physicaldrive 1:7 (box 1:bay 7, SATA, 250 GB, OK)
physicaldrive 1:8 (box 1:bay 8, SATA, 250 GB, OK)
physicaldrive 1:9 (box 1:bay 9, SATA, 250 GB, OK)
physicaldrive 1:10 (box 1:bay 10, SATA, 250 GB, OK)
physicaldrive 1:11 (box 1:bay 11, SATA, 250 GB, OK, spare)
The status for each physical disk should be set to OK. If a disk has failed or has been removed, the
disk may not be shown. Check the bay numbers to see of a disk is missing.
If a disk has failed, the output will be similar to the following, where disk 4 has failed:
=> pd all show
MSA20 at 01
array A (Failed)
physicaldrive 1:1 (box 1:bay 1, SATA, 250 GB, OK)
physicaldrive 1:2 (box 1:bay 2, SATA, 250 GB, OK)
physicaldrive 1:3 (box 1:bay 3, SATA, 250 GB, OK)
physicaldrive 1:4 (box 1:bay 4, SATA, 0 Byte, Failed)
physicaldrive 1:5 (box 1:bay 5, SATA, 250 GB, OK)
physicaldrive 1:6 (box 1:bay 6, SATA, 250 GB, OK)
physicaldrive 1:7 (box 1:bay 7, SATA, 250 GB, OK)
physicaldrive 1:8 (box 1:bay 8, SATA, 250 GB, OK)
physicaldrive 1:9 (box 1:bay 9, SATA, 250 GB, OK)
physicaldrive 1:10 (box 1:bay 10, SATA, 250 GB, OK)
physicaldrive 1:11 (box 1:bay 11, SATA, 250 GB, OK, active spare)
8. Check that there are no predicted failures.
The disks in the SFS20 array support the Self-Monitoring, Analysis and Reporting Technology
(S.M.A.R.T.) self-test to predict failures in the disk. The HP SFS system software periodically scans the
S.M.A.R.T. status of disks. If a disk failure is predicted, an event such as the following is generated:
2005/04/08 09:47:07 storage !! south1: P6C8CX7MQPS7UK: array 1: disk bay 12:
disk self monitor predicts failure (was online)
You can search for these events in the system log by entering the following command:
sfs> show log facility=storage && data contains "disk bay"
If you find such events in the log, you can confirm the current status of the disk by entering the
hpls_cciss_info command using the following syntax:
hpls_cciss_info -i -D controller,port,0,drive_number
You can determine the controller, port, and drive_number values for the array as follows:
• Determine the controller and port values by entering the show array array_number
command and looking at the numbers in the HBA/Port field of the output, as shown in the
following example. In this example, the array is connected to the servers on controller 1 and
port 2:
sfs> show array 1
