HP AutoRAID 12 H LUN Size Extension

Hi,

We have got two node cluster system with two AutoRAID 12H disk array.

Earlier each 12H has 8 disks (36 GB) and had 8 LUN with size as follows

--- Disk space usage --------------------
Total physical = 347329 MB *
Allocated to LUNs = 193096 MB *
Used as Active Hot spare = 34732 MB *
Used by non-included disks = 0 MB *
Used for Redundancy = 56250 MB *
Unallocated (avail for LUNs) = 63251 MB *
-----------------------------------------
Vendor ID = HP
Product ID = C5447A
Array serial number = 00000025CA0F

LUN 0:
Capacity (MB=2^20) = 2048 MB *
Maximum block addr = 4194304
Block length = 512

LUN 1:
Capacity (MB=2^20) = 2048 MB *
Maximum block addr = 4194304
Block length = 512

LUN 2:
Capacity (MB=2^20) = 36000 MB *
Maximum block addr = 73728000
Block length = 512

LUN 3:
Capacity (MB=2^20) = 36000 MB *
Maximum block addr = 73728000
Block length = 512

LUN 4:
Capacity (MB=2^20) = 36000 MB *
Maximum block addr = 73728000
Block length = 512

LUN 5:
Capacity (MB=2^20) = 27000 MB *
Maximum block addr = 55296000
Block length = 512

LUN 6:
Capacity (MB=2^20) = 27000 MB *
Maximum block addr = 55296000
Block length = 512

LUN 7:
Capacity (MB=2^20) = 27000 MB *
Maximum block addr = 55296000
Block length = 512

Total capacity allocated to LUNs = 193096 MB

Recently, I have added 2 disks (A&B) in both disk array( Total 4 disk 36 GB)

We would like to extend one Logical Volume size which is not a part of Cluster volume group.

As we have already reach maximum limit of 8 LUNS, we can not create further. What should I do for LV extension

Do I need to delete that particular LUN and then create with new large size then create VG and LV or shortly can I extend LUN size.

Pls. advise

Thanks in advance

Re: HP AutoRAID 12 H LUN Size Extension

NH,
backup, delete, recreate and restore. 12h is not capable of extending LUNs
