how to remove alternate links for the disks
I have lost the /etc/lvmtab file. I thought by vgscan i can recover the same. After performed the vgscan, i checked the output of /etc/lvmtab.
It was displaying some more disks as well. why is this displaying all the other disks. but when i am doing vgdisplay -v (volumegroupname), it displaying the same physical volumes as alternate link to the PV. can you help me, how i can retrieve /etc/lvmtab to the normal ealier position?

Re: how to remove alternate links for the disks
From my understanding, vgscan gives you the lvm config of your present environment.
So. logically the "alternate links" - I guess what you mean by extra disks, is presently a part of your OS environment.
So why do your want to forcibly remove the redundancy?
Anyways, if you really want the old lvm configuration, I GUESS you should have a local backup copy or get it from the latest ignite backup you had made...I think so...
The expert here will give us better suggestions,possibly.

Re: how to remove alternate links for the disks
Please try vgscan in preview mode as
# vgscan -N -p
it will scan the VGs with their persitant Device file names. if the output satisfies you, then remove -p option and run vgscan as
# vgscan -N
