## Verify the Functionality of a Hard Drive

1. If the OS is shut down, and the drive you replaced was not the boot device, boot the OS.

   Depending on the nature of the replaced drive, you might need to perform administrative tasks to reinstall software before the server can boot. Refer to the Oracle Solaris OS administration documentation for more information.

2. At the Oracle Solaris prompt, type the `cfgadm` `-al` command to list all drives in the device tree, including any drives that are not configured:

       # cfgadm -al

   This command helps you identify the drive you installed.

       Ap_id             Type        Receptacle   Occupant       Condition
       c0                scsi-bus    connected    configured     unknown
       c0::dsk/c1t0d0    disk        connected    configured     unknown
       c0::sd1           disk        connected    unconfigured   unknown
       usb0/1            unknown     empty        unconfigured   ok
       usb0/2            unknown     empty        unconfigured   ok
       .
       .
       .

3. Configure the drive using the `cfgadm` `-c` `configure` command.

   Example:

       # cfgadm -c configure c0::sd1

   Replace `c0::sd1` with the drive name for your configuration.

4. Verify that the blue Ready-to-Remove LED is no longer lit on the drive that you installed.

   See Hard Drive LEDs.

5. At the Oracle Solaris prompt, type the `cfgadm -al` command to list all drives in the device tree, including any drives that are not configured:

       # cfgadm -al

   The replacement drive is now listed as configured. Example:

       Ap_Id            Type         Receptacle   Occupant      Condition
       c0               scsi-bus     connected    configured    unknown
       c0::dsk/c1t0d0   disk         connected    configured    unknown
       c0::dsk/c1t1d0   disk         connected    configured    unknown
       usb0/1                        unknown      empty         unconfigured ok
       usb0/2                        unknown      empty         unconfigured ok
       .
       .
       .

6. Perform one of the following tasks based on your verification results:
   - If the previous steps did not verify the drive, see Diagnostics Process.
   - If the previous steps indicate that the drive is functioning properly, perform the tasks required to configure the drive. These tasks are covered in the Oracle Solaris OS administration documentation.

   For additional drive verification, you can run Oracle VTS. Refer to the Oracle VTS documentation for details.
