No Blue LED When cfgadm -c unconfigure disk (22724487)

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:

1. 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 
       ....
     

2. Check the drive's status.

       # cfgadm -al Ap_Id
       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    configured   unknown 
       c3::w5000cca02d0f6dbd,0  disk-path  connected    configured   unknown 
       ...
     

3. 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 
       ...
     

4. 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. 
     

5. Confirm the Ok to Remove LED is on.

       # fmadm get-indicator /dev/chassis/SYS/HDD3/disk ok2rm
       The indicator (ok2rm) is set to on. 
     

6. It is safe to remove the drive.
