2.7.8 Cloning hard disks
When a hard disk is likely to become faulty or develop errors, for example,
when the number of reported errors or bad sectors of a physical disk
increases over a certain threshold, or a disk reports SMART warning, you
can copy all the data on the disk to another disk.
To clone a hard disk, do the following:
1. Select Maintenance Utilities > HDD Clone from the main menu.
2. Click Clone and specify the following disk cloning options.
Note
1. The volume must be in optimal state.
2. There must be at least two concatenating volume units in a
volume.
3. All selected volume units must be the last concatenating volume
units in the volume.
Source Disk Select a source disk you want to clone. The disk
must not be in an NRAID disk group.
Target Disk Select the target disk to be the clone. The disk
must be either unused, a global spare, or a local
spare of the same disk group as the Source Disk.
Schedule Immediately: The task will start immediately.
Once: The task will start on the specified date and
time.
Automatic
Resume During cloning, if the target disk fails, the controller
will use another disk and resume cloning. [The
Auto Spare Control option (see 2.7.16
Miscellaneous on page 2-55) must be set to On.]
The following is the order of disks used to resume
cloning:
1. Local spare disks
2. Global spare disks
3. Unused disks
If there is no disk to resume cloning, or this option is
not specified, cloning is aborted when the target
disk fails.
