While trying to mount the clone lun to the secondary server and accessing the data, it was not possible to do so since it shows some file system corrupted. Also i tried using admsnpa clone_activate command to scan for the new device in the secondary server where the clone lun is been presented. This command also does not work properly the error was that " Clone activate command was valid but it was not compatible with the Linux server". We have a linux server of RHEL 5.3. I could not able to find any clue why this is been happening like this.
on 2.6 kernels you should be able to run these two commands for each HBA to rescan for new storage, sometimes even that does not work and we have to bounce the box. It does not happen as often as it used.

for a test, can you unmount and export volume group on source server, fracture the clone and then import on target server.

Finnaly i got the clone lun detected after a reboot. I think Linux servers always needs a reboot after we allocate the lun to the server ?
