NetApp – Fix the “Bad Label” issue

NetApp – Fix the “Bad Label” issue

Recently I came across with a Bad Label error during the change of failed disk. My company changed the support company for one of our systems and the new one sent disks to replace the failed ones from the system. Normally the DC tech make a swap and assign the disks to the system, but this time he called me with an issue (from /etc/messages):

Thu May 22 13:02:54 CEST [NETAPP: raid.config.disk.bad.label:error]: Disk 9.10 Shelf 6 Bay 9 [NETAPP X291_S15KXXX0F15 NA01] S/N [3QQ312Y2XXXPBW] has bad label.
Thu May 22 13:02:54 CEST [NETAPP: raid.config.disk.bad.label:error]: Disk 6.70 Shelf 4 Bay 7 [NETAPP X291_S15KXXX0F15 NA01] S/N [3QQ3097KXXX5VU] has bad label.

 

To fix the issue I did:
