Extending RAID 5 (HP DL380 G5)

m4cc45 · 27 May 2008 at 12:12

Hi,

I think I need a 3rd party piece of software to do this (if so whats it called)?

Basically we have a HP DL380 G5 server.

It originally had 5 hard-drives RAID 5 (all 146GB) in there split into 3 partitions running Windows 2003 (fully updated).

C: O/S
D: DATA
E: Stuff

Now we have added an extra 3 hard-drives (all 146GB) and want to extend the current array - however the option is not present in HP ACU.

We want the rest of the space to be assigned to E: as well. Is there an easy way to do this. I'm sure I didn't have this many problems when I last did this.

Any software that I might need (regardless of the cost) would be good as well.

Thanks,

M.

I work for a Building Society mate. Didn't realise you were in Gloucester (as I've seen you around a lot). I actually work in Stroud but live in Gloucester.

Yup - which department do you work in?

There was a techy job as a trainee which has just gone but there may be more coming up - on the website is a vacancies list but if I hear anything I'll give you a shout.

I can't find anything on the ACU at all I've created a new raid set and tried to see if I can merge it to no joy there is no extend option what-so-ever though in the documentation it says there is.

Sigh!

Perhaps a Stroud reunion drink sometime in the future?

Well when I go into the ACU (Array Configuration Utility for those who haven't heard of it before) there is no option to extend. So I have 5 disks in a RAID 5 array. Array A in this case. So if I create a new array, Array B, then when you go to Disk Management it's seen as a new disk so you can't extend it.

I've read the manual and there is an extend option but I can't seem to see what I'm missing - there must be an easy way to do this but for the life of me I can't see it - lol

Hi Mate

Thanks for that - however still doesn't work (i've attached a screenshot).

The controller is the onboard Ultra 320 SCSI controller SmartArray P400.

Can't see any manage/extend options.

Damn. I think it may be because of that (the company who provided the servers were a bunch of cheapskates).

Let me look into it.
