Extend Raid5 On DL380 G3

Hi Guys,

I have a customer having an old DL380 G3 wishing to extend his Raid5 Array.

Situation is as below.

Raid 0 on 2x9.1Gb for OS

Raid 5 on 3x18.2Gb + 1x18.2Gb(Online Spare) for Data.


I haven't got much experience with the G3's, is there a possibility of removing the Online Spare disk as the spare, and extending the Raid5 with it?

Anyone has the steps to proceed?

Thanks

Re: Extend Raid5 On DL380 G3

The G3 has a 5i Plus builtin raid controller. It can also have a different controller added on. Verify which controller it is.

Then the raid controller must have the BBWC option (battery cache) to be able to do what you are planning. If it does, you can expand the existing array online.

You need to
1. Unconfigure the hot spare drive
2. Capacity expansion (add the drive to the raid5 array)
3. Logical drive expansion (or create new logical drives)
4. OS partiton expansion (or create new OS partitions)

Thanks TTr,

Just another question.

You've said that it is possible to perform the expansion Online if there is a BBWC attached to the controller.

In the event that there is no BBWC, is it then totally impossible to perform the expansion, or is it possible to do it in Offline Mode.

cheers for replying.

If there is no BBWC you can not do these operations, online or offline. If your server has windows OS and you have ACU installed, check out the controller. You will se if the BBWC is installed or not. Also you will see if those options are enabled or not in the ACU menus.
