Issue

After adding a new disk shelf to the system, one of the disks has no LED lit , although the below two conditions are met:

The disk is detected normally by ONTAP and the status is normal from "sysconfig -a" output as shown below:

Cluster::> run -node <node-name> -command sysconfig -a

04.21: NETAPP X477_TTCRE04TA07 NA01 3807.8GB 520B/sect (89X0A0PLXXXC) 04.22: NETAPP X477_TTCRE04TA07 NA01 3807.8GB 520B/sect (89X0A0DYXXXC) 04.23: NETAPP X477_TTCRE04TA07 NA01 3807.8GB 520B/sect (89N0A0LZXXXC)

2. The disk is seen in the spare pool after assigning it to a node:

Cluster::> run -node <node-name> -command sysconfig -r
