Chapter 4: RAID Array Maintenance

Logical Drive Maintenance 4-5

4.1.3 Copy & Replace

One major benefit of Copy & Replace is that you can expand your

RAID arrays online without purchasing new enclosures for additional

capacity. Members of a RAID array can be replaced by drives of

larger capacity.

Precondition:

You should have at least one drive tray which is not currently

responsible for host I/Os, i.e., a new/used drive.

To replace a member drive, follow the steps below:

Step 1. Click on the Copy & Replace function link on the

navigation panel. Select a source drive, a member of a

logical drive, by a single mouse click.

Step 2. Select a new/used drive by a single mouse click.

Step 3. Verify the slot number of the selected Source and

Target drives. Click the APPLY button to confirm or

click RESET to cancel the previous selections.

Firmware will start cloning data from source to target

drive. The Source drive will be replaced by the Target

drive, and will be taken offline.

Note that the location of member drives will be different

after Copy and Replace.
