Extend drive space...

[Gops_1]

Hi all,
I have database server in which the drives are mounted on SAN VA7110. One of the path in my DB server is 98% i wish to extend this.
I wish to know the following,

1. How much free space available on my SAN.
2. How can use that free space to extend that 98% drive path,

I am attaching that bdf details below.

This is critical prodution server. I need a expert to reply to this,

Bdf as follows,

/dev/vg00/lvol3 1540096 1436200 103096 93% /
/dev/vg00/lvol1 497584 89168 358656 20% /stand

/dev/vg01/lvol6 4096000 2042896 1924848 51% /pdwp1pkg/u06

You can see one drive path is 98%. I wish to extend this using the available free space in SAN.
Lot of points...

FYI: vg01 is mounted on SAN VA7110.

Thanks

As far i can see: is this server is a part of the cluster ?

The procedure is easy:
1. present disks (LUNs) from VA7110
2. Add this disks in the volume group vg01 (check for mirrors, etc ...).
3. extend the partition(s).

In case of cluster volume group you need to export it in PREVIEW mode and create map file for importing on the other node(s).

1. How much free space available on my SAN.

vgdisplay -v /dev/vg01 |more --> need out put

PE Size (Mbytes) ?
Free PE ?

PE Size * Free PE = (Free Space left under vg01)

2. How can use that free space to extend that 98% drive path,

I am attaching that bdf details below.
(bdf - out put will not help vgdisplay /dev/vg01 out put needed)

Question:-

Do you have Online -JFS if not we can't extend with-out umounting the File system

if Yes --> we can extend file system "ONLINE"

swlist |grep -i JFS --> need out put to check Online JFS Installed

Hi,

do you have commandview sdm installed on your server?

if you do, please run these command
1. armdsp -i -> notify your alias_name
2. armdsp -a

second command will give you the configuration of the VA7110

Sandy

Hi Ivan,
Yes its in HP Service guard cluster.

you have list the steps 1,2,3 . I am not much to into this SAN and HP Ux.
Let me knw the exact command o/p you need for. Assist me according to that.

Thanks

Hi Johnson,
I've attached the vgdisplay as you requested for. I didn't see any JFS there.

There are 3 more servers sharing those SAN storage.
1. OVO server
2. remedy server
3. Backup server (HP storage Data protector)
4. Database server ( I wish to extend on this server)

What more details you need ?

Thanks

Hi Gops,

Many Thanks for attachements

I've attached the vgdisplay as you requested for.
>>>vgdisplay<< show you have only 900 MB free space left ...:(

You need Add more disk ,

Also you have mentioned "Cluster"

ONLINE -JFS is much needed for this "becoz" if your "Logical Volume part" of Cluster pkg we need "haltpkg" and "vgextend" for "vg01" than "vgexport" map file "vgimport" the map files to Failover Node"

I didn't see any JFS there.

>>>(I didn't see any JFS there --> You need downtime for "DB Server") <<<<


Thanks
Johnson

Hi Sandy,
I have command view SDM. I am attaching armdsp -a.

Hi johnson,
What is JFS, how can load that into my HP UX server. I am having HP UX 11.0

[Gops_1]

Hi johnson,
I am happy that we have 900 MB free space. As i am having a SAN VA7110. I wish to know how much space am having in SAN server. If i get some good space in SAN,
1. I will add that space to this DB server
2. I will use your steps to use that free space and extend that drive

So my present requirement is

1. I wish to know what is my current SAN configuration
2. Can i use my SAN space effectively.

Everything is there in front of us. But there is lack of visibility. This applies to me.

thanks

So my present requirement is

1. I wish to know what is my current SAN configuration

CAPACITY USAGE

Total Disk Enclosures:________________1

Redundancy Group:_____________________1
Total Disks:________________________15
Total Physical Size:________________500.679 GB
Allocated to Regular LUNs:__________130.107 GB
Allocated as Business Copies:_______110 GB
Used as Active Hot Spare:___________66.757 GB
Used for Redundancy:________________193.083 GB
Unallocated (Available for LUNs):___748 MB

2. Can i use my SAN space effectively.

Yes, you can ,

Everything is there in front of us. But there is lack of visibility. This applies to me

In this Case can you Check with any Storage Support Admin for this Server,..?

to help you figure-out and provide you

Device Path /dev/dsk/cxtxdx

so using those free Device path we can vgextend /dev/vg01

Thanks,
Johnson

Hi,

From the armdsp, I can see that your VA has only 748 MB unallocated disk space. You can create a new lun on the VA, present it to the server and extend the VG. Do you need a step by step guide how to do that?

Sandy
