Recovery from a hard disk failure
If a hard disk breaks, the broken disk must be replaced immediately. This section describes alert reports and
status shown by the Data Viewer while disks are replaced to restore mirroring.
(1) Detecting problem of a hard disk
See [1. Confirm of hard disk failure] above.
(2) Removing the hard disk
Disconnect the hard disk with the problem. At this time, ESMPRO Agent reports the following alert to
manager. And icons related to the hard disk with problem change the state of warning in the data viewer.
Since the hard disk has been removed, the status of the SCSI slot will be “EMPTY.”
