Hi Sujeet,

The purpose of language is to communicate, if others understand you then that is OK. I think you made yourself very clear so do not worry about the other reply.

We do have a cluster in our model but it has more then 6 nodes so cluster lock was not implemented. Hope you can get answer soon and Have a nice weekend.

thanks

Dear Mr. Dhananjay, This is not an english class and nobody here in forum wants to learn English grammer.
This is the place where you share your technical knowledge.
So go ahead and make yourself enriched with HPUX and not with english.

Sujeet if you asking about how to setup lock disk then:

1. Select a LUN (which is already under RAID 5) cxtxdx
2. pvcreate -f /dev/rdsk/cxtxdx
3. mkdir /dev/lckgrp
4. mknod /dev/lckgrp/group c 64 0x010000 {Make sure u hv unique minor no.
5. vgcreate -f lckgrp /dev/dsk/cxtxdx
6. vgdisplay lckgrp
7. vgchange -a n lckgrp
8. vgexport -p -v -s -m /etc/lvmconf/lckgrp.map lckgrp
9. Push this map file to all other cluster nodes
On all other nodes:
10. mkdir /dev/lckgrp
11. mknod /dev/lckgrp/group c 64 0x010000
12. vgimport -s -v -m /etc/lvmconf/lckgrp.map lckdsk

Hope that helps.
Regards,

Hi,

Doing this will involve recreating the raid again and then restoring data. Cluster lock has nothing to do with this, only after reformation the same disk device file should be available.

But as I said it will require reformation. So
1. Backup and test it, Shut cluster.

2. Recreate raid 5 and create file systems and other necessary things and restore data.

3. Test applications and insure that the device files are same. Now start cluster and see of everything is fine. I would also wish to test the cluster lock by removing one lan cable at this stage.

Another good alternative will be to add and create another raid-5 logical volume with existing controller and use that space within existing cluster after slight midifications. When everything is fine remove old disk and destroy old LV's. This will be fast and you will not require to restore backup which in some cases may be a very lengthy process.

Also language shall not be a problem in the forum if you can make your situation understood by others in whatever language it may be.

A better forumer is known by his contributions to the forum and importantly if he is not making contributions then by assigning points to the responses to his questions. So you can ignore that language improvement response.

HTH,
Devender
