## Remove a Hard Drive

A hard drive is a hot-service component that can be replaced by a customer.

1. Locate the drive in the server that you want to remove.
   - See Front Panel Components for the locations of the drives in the server.
   - See Locate a Faulty Hard Drive to locate a faulty drive.
2. Determine if you need to shut down the OS to replace the drive, and perform one of the following actions:
   - If the drive cannot be taken offline without shutting down the OS, follow instructions in Power Off the Server (SP Command) then go to Step 4.
   - If the drive can be taken offline without shutting down the OS, go to Step 3.
3. Take the drive offline:
   1. At the Oracle Solaris prompt, type the `cfgadm -al` command to 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.

      Example:

          Ap_id                       Type         Receptacle   Occupant        Condition
          ...
          c2                          scsi-sas     connected    configured      unknown
          c2::w5000cca00a76d1f5,0     disk-path    connected    configured      unknown
          c3                          scsi-sas     connected    configured      unknown
          c3::w5000cca00a772bd1,0     disk-path    connected    configured      unknown
          c4                          scsi-sas     connected    configured      unknown
          c4::w5000cca00a59b0a9,0     disk-path    connected    configured      unknown
          ...

      You must unconfigure any drive whose status is listed as configured, as described in Step b.

   2. Unconfigure the drive using the `cfgadm -c` `unconfigure` command.

      Example:

          # cfgadm -c unconfigure c2::w5000cca00a76d1f5,0

      Replace `c2::w5000cca00a76d1f5,0` with the drive name that applies to your situation.

   3. Verify that the drive's blue Ready-to-Remove LED is lit.
4. Press the drive release button to unlock the drive and pull on the latch to remove the drive.

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

5. Install the replacement drive or a filler tray.
