Replacing A Fan - Cisco 7541 Hardware Installation Manual

Replacing a Fan

Step 6
Check the hard disk drive status LED after the system has booted to verify that the hard disk drive is
operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is
faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being
accessed.
Step 7
Wait 1 minute and then verify that the replaced disk drive is in the Rebuilding state by using the show
disks details command in EXEC mode.
Note
Step 8
Wait until the rebuild operation is complete. A disk rebuild operation may take several hours. You can
check if the rebuild operation is complete by using the show disk details command in EXEC mode. The
physical drive state will be Online and the RAID logical drive state will be Okay after the rebuild
operation is completed.
Step 9
Use the show disk tech command in EXEC mode to verify that the firmware and BIOS information is
correct for both hard drives.
If you have multiple disk failures and your RAID-1 logical status is Offline, you must recreate the
RAID-1 array. For more information on disk removal and replacement procedures, see the
Area Application Services Configuration Guide
