Expand raid 1 capacity

[George Nikolaidis_1]

Hello we have a blade with a server 460 blc and and embedded E200i smart array.Initialy we had 2 146 gb sas disks.We have gradualy changed the hard disks to 300GB ,but of cource the raid shows capacity of 146GB. Within the windows 2003 OS we have run ACU but have noticed that there is no EXPAND array option.My question is if i run the auto configuration it builds a second raid_1 array. If i use the Live linux Gparted to extend my partitions will it work that way in order to have one array of 300GB? What other alternatives i have? Thank you.

Hi George,

bl460c G1 server comes with Integrated HP Smart Array E200i RAID controller with 64 MB cache.

E200i controller does not support RAID 5, Capacity Expansion, RAID migration, and Stripe Size Migration with 64 mb cache. You need to upgrade the Cache module to enable raid expansion option on E200i controller.

351580-B21 : 128MB Battery-Backed Cache Enabler

Addition of the battery backed cache upgrade enables BBWC, RAID 5, Capacity Expansion, RAID migration, and Stripe Size Migration.

Other option that you have without buying an additional cache module is, backup the info, delete the array and recreate array to use the full capacity.

Hope this helps,
