[Linux-cluster] mounting a replicated lun

[Paras pradhan]

Thanks. So after vgimportclone ,  I can mount my new lun it seems (?).

What if I remove the original lun (undefine from SAN) from the node so that
only the new lun is seen from the os? If I do that I don't even need to
vgiimport and I can mount the lun with the same vgname? Am i correct?

Thanks
Paras.
