HP Proliant ML370 G5 Can't expand the array

Hi all,
I have an Proliant ML370 G5 , 1 have 5 SAS 72GB, 2 HDDs using RAID 0+1 and others RAID 5, now i want to expand 3 more 72 GB SAS Hard disks in SAS array RAID 5.
But the ACU don't show Expand Array as picture
I have read the HP document . It say: "NOTE: Expand array is listed only if there is an unassigned physical drive on the controller.
The unassigned drive must also have a capacity no less than that of a drive in an existing
array .
Do you have any way to expand my array ?
Please help me!!!!!!!!!
Thanks so much

Re: HP Proliant ML370 G5 Can't expand the array

hi khuyen


since you have a P400 controller
you need BBWC upgrade as specs states in order to have the expand option and other options

http://h18004.www1.hp.com/products/quickspecs/12400_na/12400_na.html

#Online array expansion (with BBWC upgrade)
#Online logical drive extension (with BBWC upgrade)
# Online RAID level migration (with BBWC upgrade)
# Online strip size migration (with BBWC upgrade)

Part you need
Battery-backed write cache upgrade
383280-B21

Re: HP Proliant ML370 G5 Can't expand the array

hi

yes that's the only way if you want to add those HDDs

well I am not sure about this some people say if you smartstart CD booting the server the option will be available and you won't need to buy that part

to tell the truth I have not had the opportunity (it can be a urban legend - kidding) to test that

But I think people say that because if you read this
"#Online array expansion (with BBWC upgrade)"

so some people say ONLINE means while server is running OS and if you try offline rebooting server using smartstart CD you will the option

so from my part you can that and once let me know if that is truth

Re: HP Proliant ML370 G5 Can't expand the array

Hi Karlo,
I restart the server and insert smart start CD, when going to ACU, it don't show me the function "Expand Array".
Do you have any ideas about this ? Should i install newest version of ACU, i am using version 7.85.18.0
Thanks sir,

Re: HP Proliant ML370 G5 Can't expand the array

well

so SSCD is false

no there is no other way, you have to buy that BBWC or create a new logical drive

Re: HP Proliant ML370 G5 Can't expand the array

Hi Karlo,
I see in the website: http://h10010.www1.hp.com/wwpc/th/en/sm/WF06c/A1-1697201-12423414-12423414-12423862-12423862-70920773.html
They write :"For Smart Array P400 Controller only. If you install the Battery-backed write cache as an upgrade to a Smart Array P400/256MB Controller, you must also order part 417836-B21 (HP Smart Array P400 24 Inch Battery Cable Kit)."
So i think i have to order 2 module :
1- 417836-B21 HP Smart Array P400 Battery Attach Kit
2- 383280-B21 BBWC Upgrade
Is it true ?
Thanks sir

Re: HP Proliant ML370 G5 Can't expand the array

Hi Karlo,
Yes, i use the BBWC as your recommend .I have just expand Array and extend the logical drive , after that i use the diskpart tool of microsoft. it working OK ,
- Do i need to remove the BBWC after expand the Array ?
- After finish everything i use the ADU to check an array and i receive this message :
"Consolidated Error Report:
Controller: Smart Array P400 in slot 1
Device: Logical Drive 2
Message: Background parity initialization is currently queued or in progress on this logical drive. If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve."
Please read the attach file for more detail
Could you please explain me why the ADU report this message ?
Thanks sir

hi

"Do i need to remove the BBWC after expand the Array ? "

no at all, leave it in the server


"...Could you please explain me why the ADU report this message ? "


it is just informational message since since your added more HDDs data needs to be striped and parity has to be calculated again that's way you see that message there it will be gone in a few days it depends on:
- HDDs speed
- server workload
- amount of BBWC
- RAID level
- how many HDDs

something else I found about that message:

Background Parity Initialization

check this advsory
