i am surprised to see why the disks are showing associated with a vg prior to vgimport. Do you think a LUN initilise(pvcreate) will help? The data on the disks are restored from netaps snap volume which is a PROD data from vg vghw_rds3_p1. I tried importing with a different vg name and failed.

let ms know if you have any suggetion.

According to your output the physical volumes belong to the volume group named "vghw_rds3_p1" but your vgimport, you were referring to vghw_rds3_ptest.
The command you wanted to type should look something like this:
vgimport -v vghw_rds3_p1 /dev/sd[nopqr]

Perhaps you would like to run the vgscan first as suggested by the pvscan command ;)

that was my second attempt with a different vg name. First tried with vghw_rds3_p1 only.
