ERROR: Wrong slot  1 mapping to HBA target : 0

Output of 'mount -l' command shows that /dev/sda and /dev/sdb are mapped to wrong partitions

/dev/sdb4 on /u01 type ext4 (rw,nodev,noatime)
/dev/sda4 on /u02 type ext4 (rw,nodev,noatime)
/dev/sdc1 on /u03 type ext4 (rw,nodev,noatime)

The correct mapping is:

/dev/sda4 on /u01 type ext4 (rw,nodev,noatime)
/dev/sdb4 on /u02 type ext4 (rw,nodev,noatime)
/dev/sdc1 on /u03 type ext4 (rw,nodev,noatime)
