2.4.2 Restoring the redundant configuration manually

This section provides information on how to replace a failing internal disk and restore duplication.
1. To isolate the failing disk from redundant configuration, run the esxcli storage mpm fail and esxcli
storage mpm remove commands with device name and kernel device name specified.
The following is an example of command prompt for the procedure from isolating the internal disk stored
in the slot 0 of PCI Module 1.
# esxcli –s xxx.xxx.xxx.xxx storage mpm list

•
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.)
Note
The remove command will fail if disk status is other than [faulty]. You should change disk
status by running fail command in advance. Run the remove command without
intermission because the disk status returns to [in_sync] in a short time after running the
fail command.
