Hi Fadia,

This failed disk is part of a Hardware RAID1 set, you can replace the disk online the raid controller will rebuild the RAID1 set.

You have good disks in positions 1,2 and 3

You could try to run the below command to verify which disk is missing/failed.

# sasmgr get_info -D /dev/sasd0 -q phy=all
