3-6 ESX Operation and Configuration
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 the status
indication of them disappears and the status of each disks become "in_sync".( It comes
to take time depending on disk space.)
In executing the commands "mpmadm –f" and " mpmadm –r" with setting the RAID
1.
device name and the Kernel device name of disk , the disk is isolated 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 executing the commands "mpmadm –a" with setting the RAID device name
and the Kernel device name of disk.
The following is an example of command prompt for the procedure from isolating the internal disk
stored in the slot 1 of PCI Module 1
# cd /opt/ft/sbin/
# ./mpmadm -l
mpm0 [2/2]
|_ vmhba110500:C0:T0:L0
|_ vmhba100500:C0:T0:L0
(Isolate the disk from the RAID configuration by specifying the Kernel Device name of
slot 0 of PCI Module)
# ./mpmadm -f mpm0 vmhba110500:C0:T0:L0
Successfully set disk vmhba110500:C0:T0:L0 faulty in volume mpm0.
# ./mpmadm -r mpm0 vmhba110500:C0:T0:L0
Successfully removed disk vmhba110500:C0:T0:L0 from volume mpm0.
(Check if the disk specified is isolated from the RAID configuration.)
# ./mpmadm -l
mpm0 [1/2]
