This issue only applies to servers running the Oracle Solaris 10 1/13 OS.
If you use the cfgadm command to unconfigure a drive, the drive's blue Ok to Remove LED might not illuminate. This issue makes it difficult to confirm that the drive is ready to be removed and to identify the drive's physical location.
Workaround: Perform these steps to confirm that the drive is ready to be removed and to identify the drive's physical slot.
Use the cfgadm command to identify the drive's WWN that you plan to unconfigure.
In this example, the fifth drive will be unconfigured. The fifth drive has a WWN 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, as identified in the last line of this example.
# 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 WWN 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 WWN to identify the drive's location (HDD4 in this example)
Look at the line after the line with the WWN. The word offline indicates the drive is unconfigured.
