If POST runs as part of the boot sequence, and if the system experiences hardware faults, you might see a POST ERROR message, followed by an INFO message. The boot sequence continues, but the system might contain untested hardware. The untested hardware will be available to the operating system after the boot.
For these cases, POST stalls for several minutes, then it sends an e-report, as in the following example:
2013-01-23 15:30:55:990 0:0:0>ERROR:

Use the cfgadm command to identify the drive's WWID that you plan to unconfigure.
In this example, the fifth drive will be unconfigured. The fifth drive has a WWID of w5000c50033278c09,0.
# cfgadm -al | grep disk c7::w5000cca016065039,0 disk-path connected configured unknown c8::w5000cca0257b4999,0 disk-path connected configured unknown c9::w5000cca0257ca335,0 disk-path connected configured unknown c10::w5000cca03c252999,0 disk-path connected configured unknown c13::w5000c50033278c09,0 disk-path connected configured unknown
Unconfigure the drive.
# cfgadm -c unconfigure c13::w5000c50033278c09,0
Verify that the drive is unconfigured.
# cfgadm -al | grep disk c7::w5000cca016065039,0 disk-path connected configured unknown c8::w5000cca0257b4999,0 disk-path connected configured unknown c9::w5000cca0257ca335,0 disk-path connected configured unknown c10::w5000cca03c252999,0 disk-path connected configured unknown c13::w5000c50033278c09,0 disk-path connected unconfigured unknown <<==
If the drive Ok to Remove LED does not illuminate perform the remaining steps.
Send the output of the prtconf -v command to a file.
# prtconf -v > /tmp/prtconf.out
Open the file with an editor and search for the WWID of the unconfigured drive (5000c50033278c09 in this procedure's example).
In the output, confirm the drive location and that the drive is offline.
Look two lines above the WWID to identify the drive's location (HDD4 in this example)
Look at the line after the line with the WWID. The word offline indicates the drive is unconfigured.
