Appendix C: On-line Capacity Expansion
Examples of On-line Capacity Expansion
Recently, we have introduced new firmware feature – online RAID capacity
expansion. It allows the user to add drives to an already created RAID set and
dynamically expand capacity over these drives. In this appendix we will give
some examples and show how this is done.
Backup Recommendations
Before you expand the capacity of your existing RAID set, we strongly
recommend you have a current backup of data contained on the RAID. This
feature has only recently been implemented and has not been fully regression
tested. In order to avoid the loss of crucial data and programs you must have a
current backup prior to attempting to expand the capacity of the RAID array.
