No, you can not, sorry.

The VA7410 requires fibre channel disk drives in a HP pre-merger form factor. The 286714-B22 is a parallel SCSI disk drive in a 'Digital/Compaq classic' universal disk drive carrier.

Hello again,
I have a VA7410 storage which have 10 x HDD 73GB. What is the minimum number of HDD (73GB or 146GB) which I can put in VA7410? Can I put 1 x HDD 146 GB? Where can I find informations (tutorials, how-to, etc) about I add this HDD to the space of storage
Thank again

Re: HDD for VA7410

Uwe Zessin — Wed, 04 May 2005 08:37:14 GMT

The VA7410 requires a minimum number of 10 disk drives. It is written in the specifications at HP's web site.

http://h18006.www1.hp.com/products/storageworks/va7110/specifications.html

(The link says '7110', but the content is for both, the VA7110 and the VA7410).

Hi,

How many enclosures you have?
If it is main only, then 15 disks are possible in total.
If you have 10 already, you can add 5 more, preferably same capacity and speed.
If you mix the capacity then you may not be utilizing the larger capacity, especially if you are adding only one.

Hi,

I have one enclosure, and it is main only.
I have 10 HDD (73GB)already.
The questions are:
Can I put in storage and use only one 146GB HDD?
Can I put in storage and use only one 73GB HDD?
If I can't put and use only one 146GB HDD what is the minimum number of HDD which I must put in storage?

Regards,
Alin

Hi alin again.
Can. BUT VA7410 has 2 RG (redundancy group) You shold consider which slot you insert disk to
1. run this command
#armdsp your_VA_ALIAS
#ioscan -fnC disk
#vgdisplay vgXX
vgXX is vg you want to extend lv.

Re: HDD for VA7410

alin_5 — Thu, 05 May 2005 04:42:20 GMT

Hi Tienna,
If I run the commands you say me, I add a new HDD and grow-up the space of storage?
What is your opinion about this:
I have one enclosure, and it is main only.
I have 10 HDD (73GB)already.
The questions are:
Can I put in storage and use only one 146GB HDD?
Can I put in storage and use only one 73GB HDD?
If I can't put and use only one 146GB HDD what is the minimum number of HDD which I must put in storage?

Thanks many more again
Alin

Re: HDD for VA7410

I think VA7410 has two RG (like VA7400)(refer attached file). To determine correctly i need you run this command
#armdsp -a your_VA_name
then check number of RG (FOR EXAMPLE)
CAPACITY USAGE

Total Disk Enclosures:________________2

Redundancy Group:_____________________1
Total Disks:________________________11
Total Physical Size:________________367.164 GB
Allocated to Regular LUNs:__________245.097 GB
Allocated as Business Copies:_______0 bytes
Used as Active Hot Spare:___________33.375 GB
Used for Redundancy:________________87.832 GB
Unallocated (Available for LUNs):___880 MB

Redundancy Group:_____________________2
Total Disks:________________________9
Total Physical Size:________________300.407 GB
Allocated to Regular LUNs:__________190 GB
Allocated as Business Copies:_______0 bytes
Used as Active Hot Spare:___________33.375 GB
Used for Redundancy:________________76.93 GB
Unallocated (Available for LUNs):___104 MB

>> IT MEAN VA7400 HAS TWO RG(Redundancy Group)
YOUR QUESTION
Can I put in storage and use only one 146GB HDD?
>>CAN. VA7410 SUPPORT FO 146gb DISK. THIS DISK WILL BE HOT SPARE DISK (SEE ATTACHED FILE FOR CONFIG)
Can I put in storage and use only one 73GB HDD?
>> OFFCOURSE
If I can't put and use only one 146GB HDD what is the minimum number of HDD which I must put in storage?
>> ONLY NEED CONSIDER SLOT TO INSERT TO (SHOULD KEEP "Unallocated Available for LUNs" IS BIGGER THAN ONE DISK)
