Re: Backup and Restore of TruCluster System

You need to backup with vdump, the root, usr, var and members boot partition. Also, you need to restore the CNX partition data, with the clu_bdmgr command.

This document may help you.

Also check the trucluster administration manual.

Thanks,
Before doing this job on customer site,
I create a cluster from one memeber, I connect 7 local disks on the server I create the cluster on three disks

Re: Backup and Restore of TruCluster System

I'm not sure what you are doing.

Are you using TruCluster 5.X?

You state "I connect 7 local disks".

You must create the cluster on a shared disk (See hardware configuration manual).

Re: Backup and Restore of TruCluster System

What you're trying to do is not easy. There are several (some recent) threads in this forum discussing the same thing. Without you showing the exact steps of what you did, it's difficult to say what went wrong. Did you change the /etc/sysconfigtab to reflect the new major/minor number of the cluster_root disk?

If you explain in a bit more detail what you're trying to accomplish, then we may be able to help you a bit better.

Re: Backup and Restore of TruCluster System

to replace a members bootdisk try this :
2) add new clustermember on new disk
3) boot from new disk
4) remove old cluster member

to prepare for "bare metal" restore try "btcreate"

Re: Backup and Restore of TruCluster System

Thanks For All,
I found my mistake
in clu_bdmgr following commands

# clu_bdmgr -d dsk1311 > /clu_mig/old_member1.cnx
# cat /clu_mig/old_member1.cnx | sed "s/dsk1307/dsk1588/g" >
/target_member1_mnt/etc/clu_bdmgr.conf
# clu_bdmgr -h dsk1593 /target_member1_mnt/etc/clu_bdmgr.conf
# clu_bdmgr -d dsk1593

I did it again for the new boot3_root
it works fine on my test invireonment
I'm ready to do it on customer site

Kind Regards
Nabil
