Dynamic Capacity Expansion - HP Surestore Disk Array 12h - And FC60 Service Manual

In the event of an unexpected disk array shutdown or loss of power, the BBU provides
power to cache memory to maintain the cache for 120 hours (5 days).

Dynamic Capacity Expansion

If slots are available in the disk enclosures, you can increase the capacity of the disk array
without disrupting operation. By simply adding new disks to the array and then creating a
new volume group, the capacity can be expanded. See "Adding Capacity to the Disk Array"
on page 200 for more information on adding disks and other ways of increasing disk array
capacity.
