Expand exising array Raid 5 in DL380

[Georgi Filipovski]

Hello,
Situation is as follows:
HP Proliant DL380 G5 server, Smart Array P400, with 6 (six physical drives) installed in total, of which:
2 (two physical drives) of 72GB in Raid 1+0 mirrored - Drive C used for Operation system;
4 (four physical drives) of 72GB in Raid 5 - Drive D used for saving files.

I want to add 1 (one physical drive) 72GB into the EXISTING Raid 5 (Drive D) Array to make more capacity.
There is no option in HP Array Configuration Utility (http://docs.hp.com/en/9320/acu.pdf), even though, they say: Expand Array and Extend Logical Drive on pages 24 and 25.

Please advice,
Georgi

Hello Georgi,

you need a BBWC attached to you P400 to do a online expansion. If you have a BBWC connected, you must add the physical disk to the array, and then you can expand the logical drive with the new free space.

There are some options, to attach a BBWC:

Smart Array P400 Battery Attach Kit 417836-B21
This option kit contains a 24" battery cable and adhesive material for installing a battery into the server if a Smart Array P400 is integrated outside of the factory. For all solutions, please refer to the server QuickSpecs and User's Manual for detailed installation instructions.

Thank you very much for your answer.
I'll be purchasing the hardware first and then I'll try to expand the array.
Sincerely,
