Replace A Wf-500-B Log Drive - PaloAlto Networks WF-500-B Hardware Reference Manual

Service the WF-500-B Appliance

Replace a WF-500-B Log Drive

The WF-500-B appliance log drives are located on the front of the appliance. Each drive pair (A1
and A2 for example) is in an independent RAID 1 array. This redundant configuration helps ensure
that there is no service interruption or loss of log data if a disk drive fails.
Do not attempt to replace a WF-500-B log drive with a third-party drive. Also, do not mix
drive models within a RAID 1 array—the drive model must be the same for both drives in a
RAID 1 array. You can, however, mix drive models in different RAID 1 arrays. For example,
the drives in the A1/A2 array can both be model ST91000640NS and the drives in the
B1/B2 array can both be model ST1000NX0423.
Disconnect all power cords before servicing the WF-500-B appliance.
STEP 1 |
Identify the failed drive and record the drive model number by running the following
operational command and viewing the status and model fields:
admin@hostname> show system raid detail
For example, the following output shows that disk drive A2 failed and the drive model is
ST8000NM0055-1RM.
Disk Pair A Available
Status clean, degraded
Disk id A1 Present
model : ST8000NM0055-1RM
size : 7630885 MB
status : active sync
Disk id A2 Present
model : ST8000NM0055-1RM
size : 7630885 MB
status : failed
STEP 2 |
Remove the failed drive from the RAID 1 array. In this example, run the following command
to remove drive A2 from the array:
admin@hostname> request system raid remove A2
