How to Locate Failed Disks

The hard disk drive in which a failure occurs can be identified. The following is an example of a failure in the hard
disk drive inserted into Slot 9.
1. Log in to the server as the root user. If you login with graphical mode, select [Others...] to login.
2. Execute "1 List RAID Arrays" of the ftdiskadm command to check the hard disk in which a failure occurs
according to the displayed information. If "F" appears at the head of "Member" of the displayed information,
this indicates that the partition of the hard disk drive is abnormal. The number enclosed in parentheses is the
slot number to indicate the problematic disk and partition.
