How to create a mirror
This option creates a
mirror
of an existing volume or source volume on
the HP Media Vault. A volume is a
portion of one or more hard disks configured
to store data. A mirror duplicates the source volume on another
hard disk.
For more information on mirroring, see
Understanding disk mirrors and concatenated disks
.
When you save files to a mirrored volume, your files are saved to both hard disks. The end result is that half the
total amount of space is available to store your files. For example, two 200GB drives mirrored together result in
a mirrored volume of 200GB, not 400GB.
Note:
When creating a mirror, you must use a blank hard disk or unallocated space on a hard disk that is the
same size or larger than the source volume you want to mirror.
If any there is not enough unallocated space on
the expansion disk, you can do one of the following: erase the disk, or resize or delete one or more volumes on
the disk. For information on how to do these procedures, see
Erase a disk
,
Modify a volume
, and
Delete a
volume
.
Data on a mirror volume is safe unless both disks fail at the same time. If one hard disk fails, the
media vault will administer a warning. The failed hard disk should be replaced immediately.
