Solution 1608495.1 : On BDA after Disk is Replaced, bdachecksw Incorrectly Reports 'Wrong mounted partitions' Error

Applies to:

Big Data Appliance Hardware - Version Not Applicable and later
Linux x86-64

Symptoms

After a disk is replaced and correctly configured on a Oracle Big Data Appliance (BDA), bdachecksw srcipt incorrectly reports 'Wrong mounted partitions' error. Also bdacheckcluster will report the same error for the node with the replaced disk .

Say disk in slot4 is replaced, in bdachecksw output /u05 disk partition is listed at the end. But all partitions are recognized correctly

ERROR: Wrong mounted partitions : /dev/md0 /boot ext3 /dev/md2 / ext3 /dev/sd4 /u01 ext4 /dev/sd4 /u02 ext4 /dev/sd1 /u03 ext4 /dev/sd1 /u04 ext4 /dev/sd1 /u06 ext4 /dev/sd1 /u07 ext4 /dev/sd1 /u08 ext4 /dev/sd1 /u09 ext4 /dev/sd1 /u10 ext4 /dev/sd1 /u11 ext4 /dev/sd1 /u12 ext4 /dev/sd1 /u05 ext4

INFO: Expected mounted partitions : 12 data partitions, /boot and /

Cause

Since sort is done early in bdachecksw script the replaced disk is reported at the end as it maps to kernel device name with higher alphabet say /dev/sdm1 and thus resulting in an error. This issue has been addressed in Bug 17899101.
