- Yes both server have same model
- On server there's 4 hdd slots of which 2 used (for OS data 1 mirrored disk )
- Have 2 extra hdd, CAN we take backup on hdd on this by inserting on free slots .
- Also am not sure that Ignite backup will restore my other application configuration files ..

-- Am preferring to go with Mirroring but .. Am sticking with proper mirroring and removing mirrored 2nd disk safely from server without any damage to LVM and that mirrored disk to be work fine on new server .. Smilie

@ VBE, Thnaks sir for your valuable guide..
Yes server have 2 disk on mirrored state, but I can't break already mirrored disk as this is on live and my mgmt doesn't allow me to do so .. I can do is I can take a downtime of secondary passive cluster and do mirroring and take out my disk .
Earlier have did such job for Linux (suse and CentOS) cases with offline dd of hdd and had worked fine .. But here my PM dosent allow me to do so as HP doesn't recommend fro dd copy of whole OS ... Smilie

and my Manager is strict with that .. and have to complete this in some deadline time ...

Here what I want ..
- Attached a 3rd hdd on secondary cluster server ... Mirror it make bootable
- Remove the HDD and connect to new server (Change IP/hostname/disableclustering make script to start all application in order cluster is -- have already made that script)
- And replace SAN data on HDD on new server ... So we have Omni backup configured so am planning to restore that data to new server same size of LV (will create a new vg on new disk and create number of LV as on original server have make entry in fstab)

Sir please advice where am missing with mirroring as have tried but that disk failed to boot .. (Steps taken were mentioned in my first thread)

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
