ACU No Spare option available

[Dorego]

Hello

Using a HP P400 Array with a raid 5.

ACU: 9.20.9

Trying to install a spare drive. But no spare option available. I have no '!' on the status and the drives are showing un-assigned.

Any help would be appreciated.

Kind Regards

hi,

Can You please remove one of the unassigned drives from the server and check after that, if the option will appear in ACU.

Thanks

Hello

Thanks for your response.

Taken one of the drives out an no different also tried putting in the next free bay. Still no Spare option. 

I have also noticed there appears no option to extend the array either..... ummmm!!!

Any ideas?

hi,

Please check your battery status. Please attach an ACU report here.

Thanks

your unassigned drives are not big enough, they need to be 160gb or more

Hi 

Battery Staus is ok - Done a diagnostic report and fine. 

I think its the Hard Disk Size. The Raid originally all had - 80 gig drives. Then over time two failed but only replacements available were 160gig. - although when these larger drives were inserted in the RAID they only actually use 80 gigs. Would that stop my replacement 80 gig drives being accepted.

Would a reasonable course of action be to 1by1 replace the 160gig drives with the 80gig drives and rebuild the raid or is this just asking for trouble? 

Cheers

hi,

The size should not be  the problem. Please attach the ACU report here.

Thanks

hi,

I think , you need 512MB BBWC module. Please test it, if you have such one.

Have you tried to add a spare in ORCA?

Thanks

Ok Thanks. 

One of other servers has a 512MB cache will try that, but will have to be a weekend job.  

I had previously added to the array using ACU but no options now. Strange. 

Never tried using ORCA will give it ago. 

Cheers
