Hi all...
Please help me because i'm very new with hp-ux.

My vendor already create 10GB of vg under my LUN which not fully use all the phisical size (64GB). How to extend this vg to 64GB without reinstall all the software installed at this vg.My os is HP-UX 11i

thanks

Let's establish some information first. This is to see the easiest method and to make sure it can be done.

Volume group information, indicating which is the volume group your referring to
e.g.
$ /usr/sbin/vgdisplay -v /dev/myvg

mounted filesystem information

$ bdf

software list
$ /usr/sbin/swlist -l fileset | grep -i JFS

I am fairly certain you won't have to re-install anything.

Could you paste in some information please? Or attach it.

bdf
vgdisplay -v

how to increase
Max PE per PV 10000 to the maximum space available (phisical size 64GB) for my hardisk.

please see the attachment for more information. urgently need a suggestion because we are working on limited hardisk space. thanks in advance.

How many other logical disks have you got?

Please provide:

# /usr/sbin/ioscan -fnkC disk

I feel this is going to first start with your disk array. Can you provide the make and model, how you manage it, (* command view, secure manger? *) its raid type (* raid 0/1/5/S, autoraid? *)

I see 10 gb only when adding vg01 and vg02 together and these are listed as LUNS c4t1d0 and c4t1d1.

Also submit 'ioscan -fnk' and 'fcmsutil /dev/td# state'.

There's a lot here to review, for example are you a SAN topology? What type? The 'fcmsutil' will indicate this.

Seems that you probably have unallocated disk in your SC10. You should be able to see it using 'armdsp -a'

I don't have too much experience with these units, but I think you need to create an extra LUN (part of your disk) using the 'armcfg' command which should help. From what I can find 'armcfg -L 3 -a array#'
See the man page for additional information, or post the output of 'armdsp -a' and I am sure someone who has more experience with these units will assist.

To be safe, I would clarify the latest procedure with the 'Response Center' but here is some basic information to review. Plan on making new LUNS in the SC10 and using LVM to incorporate them. *& I've only listed 'some' of the disk array commands below. *)

The SC10 uses the 'AM60Srvr' process from 'hparray' utilities found under '/opt/hparray/bin'

Here are some basic commands:

arraydsp -i (* display serial numbers - You'll need this whenever talking to HP *)

arraydsp -a S/N (* To check your LUNS and gather a detailed list of information on array *)

arraydsp -d S/N (* state of every driver in array *)

arraydsp /dev/rdsk/cXtYdZ (* disk info *)

arraycfg -L # -a #G S/N (* To create LUN # at size #G *)
