Linux Setup and Operation 3-5
Restoring the redundant configuration manually
This section provides information on how to replace a failing internal disk and restore duplication.
IMPORTANT:
This must be operated by root user.
While the replaced disk is restoring to the RAID configuration, do not stop/restart the system
when the reconfigured each RAID device is in RECOVERY. Wait until their status turns to
DUPLEX. Note that the wait time is proportional to the disk volume.
1.
In the command prompt of ftdiskadm, select [Remove Half Disk (RAID1)
]
to specify the
slot number of the internal disk to replace, and isolate the disk from the RAID
configuration.
2.
Remove the disk from the system, and then, insert a new disk.
3.
Wait approximately five minutes until the system automatically performs
resynchronization.
4.
If the system does not perform resynchronization automatically in step 3, recover RAID
manually by selecting [Repair Mirroring Arrays (RAID1)] in ftdiskadm.
The following is an example of command prompt for the procedure from isolating the internal disk
stored in the slot 9 (PCI module 1 - Slot 0) through restoring redundancy.
