Extending a HP MSA raid 5

Hi,

I have added 3x 300GB drives to my MSA and added them to the raid that was already made on the MSA from 6 other drives. The raid, is raid 5. That all went well and I managed to extend it fine, but instead of adding 900 odd gig, it has added about 60GB and now I have 200GB left that I can now make into a new volume, but can't add it to the raid.

Anyone know what happened? When I expanded it I was given the figure it could be expanded by and used that. Why wasn't I given the whole amount?

Best wishes

Michael

Which MSA is it, which controller if a JBOD and what size logical disk do you have now?

Sounds to me like you tried to extend past 2TB which can be rather a problem. (that's assuming above 60GB added is really 600GB added). Max LUN size on a MSA1000 for example is 2TB.

Sorry, I meant 600GB. I think that is the answer. It is an MSA1000 so that would explain it. I assume I can make a logic raid 5 drive out of what's left and start making that head toward 2TB as well?

Thanks for the reply.

Best wishes

Yup, annoying that they won't remove the 2TB limit but understandable as it's not current kit. yup, you can make another logical disk and extend that in the future just like this one.
