Logs Analysed,

Disk Id 0c.00.14 Broken

Error : Tue Oct 18 09:28:22 IST [nec-netapp1: raid.assim.disk.badlabelversion:error]: Disk 0c.00.14 Shelf 0 Bay 14 [NETAPP X290_S15K7560A15 NA00] S/N [3SL0PL9800009045W7Q5] has raid label with version (10), which is not within the currently supported range (5 – 9). Please contact NetApp Global Services.

Tue Oct 18 09:28:22 IST [nec-netapp1: raid.config.disk.bad.label.version:error]: Disk 0c.00.14 Shelf 0 Bay 14 [NETAPP X290_S15K7560A15 NA00] S/N [3SL0PL9800009045W7Q5] has an unsupported label version.

Plan Of action:

Confirm the HDD has failed via NetApp auto-support mail and note the disk ID and capacity.
Ensure the spare disk carrying for replacement is unowned and disk-label to Zero.
physical verification of the storage and identifying the failed HDD by amber notification
Ensure the status of the controller to auto-assign = false. To prevent the controller from auto assigning the disk.
login via console and check to which controller the failed HDD Id has been assigned to.
log into the controller to which failed HDD id has been assigned to
blink-on/off the led to confirm the particular HDD, (Not Necessary if there is an Amber indication on failed HDD)
remove the HDD and wait for ~60 sec and replace with the new HDD. (ensure the replaced HDD is same capacity, P/N as the replacement
check if the disk id is detected in storage.
assign the disk ID as it will be unowned
check if the disk id is taken into pool spare disks of the controller
if yes Call Closed.
