When using the cfgadm -c unconfigure command for a disk drive on a 12-disk backplane or 24-disk backplane, the blue OK to Remove LED does not illuminate.
Workaround: Use the fmadm set-indicator command to illuminate the corresponding blue OK to Remove LED, which locates the unconfigured disk. For example, to unconfigure HDD3:
Find the device path for the drive you want to remove.
# diskinfo D:devchassis-path c:occupant-compdev ---------------------------------- --------------------- /dev/chassis/SYS/HDD0/disk c0t5000CCA02D0F9E94d0 /dev/chassis/SYS/HDD1/disk c0t5000CCA02D102F60d0 /dev/chassis/SYS/HDD2/disk c0t5000CCA02D100F28d0 /dev/chassis/SYS/HDD3/disk c0t5000CCA02D0F6C44d0 /dev/chassis/SYS/HDD4/disk c0t5000CCA02D0F6DBCd0 /dev/chassis/SYS/HDD5/disk c0t5000CCA02D10366Cd0 ....
Check the drive's status.

Unconfigure the drive.
# cfgadm -c unconfigure c3::w5000cca02d0f6c45,0 # cfgadm -al Ap_Id Type Receptacle Occupant Condition /SYS/DBP/NVME0 unknown empty unconfigured unknown ... c3::w5000cca02d0eda3d,0 disk-path connected configured unknown c3::w5000cca02d0f5ca1,0 disk-path connected configured unknown c3::w5000cca02d0f6c45,0 disk-path connected unconfigured unknown c3::w5000cca02d0f6dbd,0 disk-path connected configured unknown ...
Turn on the Ok to Remove indicator for that drive.
# fmadm set-indicator /dev/chassis/SYS/HDD3/disk ok2rm on The indicator (ok2rm) has been turned on.
Confirm the Ok to Remove LED is on.
# fmadm get-indicator /dev/chassis/SYS/HDD3/disk ok2rm The indicator (ok2rm) is set to on.
It is safe to remove the drive.
