Removing and replacing a drive
Use the following procedures to remove a faulty drive from a server canister and replace it with a new one
from stock.
Attention:
•
handling electrostatic discharge (ESD)-sensitive devices.
• No tools are required to complete this task. Do not remove or loosen any screws.
• This procedure requires access to either management GUI or CLI command as a root user. IBM
service personnel need to coordinate with the customer to work on this procedure.
• You can identify the failed drive by the amber fault LED on the drive carrier. If the fault LED is lit
on a drive, it is safe to replace the drive.
You can also locate unhealthy drives in the management GUI, either from the Storage > Physical
Disks page or from the list of events that are available under the Monitoring > Events page.
You can also select the Display unhealthy devices option in the Monitoring > Hardware Details
page to see all the unhealthy devices including the faulty disks.
• Every drive slot of an operational control enclosure must contain either a drive or a blank filler,
and must not be left empty for more than 10 minutes during servicing. Ensure that you have read
and understood all these instructions and have the replacement drive available and unpacked
before you remove the existing drive.
• During the replacement process, the replacement drive is automatically checked to confirm if it
is a valid FRU and has the same capacity as all other drives in this system. The drive firmware will
be automatically upgraded, if required.
Safety preparation

the system.
