Identifying the faulty hard disk drive
To access the hard disk drives (HDDs), you must first remove the bezel from the unit.
Before you remove the hard disk drive from the system, you should first identify the faulty drive.
1. Open the Traffic Management Shell (tmsh).
2. View the status of the drives:
tmsh show sys raid
A disk summary similar to the following displays:
Sys::Raid::Array: MD1
---------------------
Size (MB)
Sys::Raid::ArrayMembers
Bay ID
---------------------------------------------------------
1
2
Sys::Raid::Bay: 1
---------------------------------------------------------
Name
HD2
Sys::Raid::Bay: 2
---------------------------------------------------------
Name
HD1
Sys::Raid::Disk
Name
------------------------------------------------------
CF1
HD1
HD2
3. Make note of the bay number and serial number for the faulty hard disk drive.
Note: You can also locate the last seven digits of the serial number on the front of the drive. The serial
number is printed in its entirety on the labels, on top of the drive.
4. Before you physically remove the hard disk drive from the system, type the following command to
remove the faulty hard disk drive (HD2 in the example) from the array:
tmsh modify sys raid array MD1 remove HD2
5. (Optional) To ensure that you remove the correct drive, you can make the LED blink for that bay (bay
1 in the example.
tmsh modify sys raid bay 1 flash-led
The LED continues to blink until the new hard drive begins the replication process.
Note: If the drive is no longer responsive, the LED might not blink.
Next, you can physically remove the hard disk drive and replace it with the new one that you received from
F5 Networks. You do not have to power down the system before you remove the hard disk drive.
