Remove a Drive or Drive Filler

Language:

You can perform this procedure while the server is running. See Component Service Categories for more information about hot-service procedures.

To hot-service a drive, you must first take it offline. This action prevents applications from accessing the drive and removes software links to it.

Determine which drive needs to be removed.
See Determine Which Drive Is Faulty.

Determine if you need to shut down the OS to replace the drive, and perform one of the following actions:
- If the drive contains the sole image of the OS or cannot be logically isolated from the server's online operations, shut down the OS as described in Power Off the Server (Oracle ILOM). Then go to Step 4.
- If the drive can be taken offline without shutting down the OS, go to Step 3.

Take the drive offline.
1. At the Oracle Solaris prompt, list all drives in the device tree, including drives that are not configured.
```
# cfgadm -al
```
  This command lists dynamically reconfigurable hardware resources and shows their operational status. In this case, look for the status of the drive you plan to remove. This information is listed in the Occupant column.
```
Ap_id                       Type         Receptacle   Occupant       Condition
c0                          scsi-bus     connected    configured     unknown
c0::dsk/c1t0d0              disk         connected    configured     unknown
c0::dsk/c1t0d0              disk         connected    configured     unknown
usb0/1                      unknown      empty        unconfigured   ok
usb0/2                      unknown      empty        unconfigured   ok
...
```
  You must unconfigure any drive whose status is listed as configured, as described in Step 3.b.
2. Unconfigure the drive.
  For example, where the drive to be unconfigured is the first drive listed in Step 3.a:
```
# cfgadm -c unconfigure c0::dsk/c1t1d0
```
  Replace c0:dsk/c1t1d0 with the drive name that applies to your situation.
3. Verify that the drive's blue Ready-to-Remove LED is lit.

Determine whether you can replace the drive using the hot-service procedure or whether you need to power off the server using the cold-service procedure.
The cold-service procedure is required if the drive has one of these characteristics:
- Contains the OS, and the OS is not mirrored on another drive.
- Cannot be logically isolated from the online operations of the server.

Take one of the following actions:
- To cold-service the drive, power off the server. Complete one of the procedures described in Removing Power From the Server.
- To hot-service the drive, take the drive offline using one of the procedures in Power Off the Server (Server Power Button - Graceful). This action removes the logical software links to the drive and prevents any applications from accessing it.

If you are hot-servicing the drive, locate the drive that displays the amber Fault LED and ensure that the blue Ready-to-Remove LED is lit.

Attach an antistatic wrist strap.

On the drive or drive filler you want to remove, complete the following tasks.

Caution - The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch.

Push the release button to open the latch.

Unlock the drive by moving the latch to the right.

Grasp the latch and pull the drive out of the slot.

Caution - When you remove a drive, replace it with a drive filler or another drive. Otherwise, the server might overheat due to improper airflow.

Install a replacement drive or a drive filler.
