Recovery from a hard disk failure
3.
If a hard disk breaks, the broken disk must be replaced immediately. This section
describes alert reports and status shown by the DataViewer while disks are replaced to
restore mirroring.
(1) Detecting problem of a hard disk
See [1. Verify of hard disk failure] above.
(2) Removing the hard disk
Disconnect the hard disk with the problem. At this time, NEC ESMPRO Agent
reports the following alert to manager. And icons related to the hard disk with
problem change the state of warning in the DataViewer.
Since the hard disk has been removed, the status of the SCSI slot will be "EMPTY."
TIPS:
You can identify the new hard disk by DevicePathID (ex. 10/40/1).
