Errors:
This disk is in a failed state with the outage reason "failed". The Disk needs to be removed and replaced.

  • But when you try to unfail the disk, it is not shown as failed

::> disk unfail c07e1.13
 
Warning: Failed disk "c07e1.13" may have aggregate labels and file system data present. In that case, this command will attempt to bring this disk back into the aggregate with which this
         disk had formerly been associated and preserve file system data. Are you sure you want to continue with disk unfail? {y|n}: y
 
Error: command failed: Failed to unfail the disk. Reason: Disk is not currently failed.
