Have you tried the vgcreate with the -v (for verbose) or -d (for

Subject: best way to make lv with 3 500G luns
What are the steps to create a volume comprised of 3 500G SGI TP9500
LUNS on SLES9?
I'm only able to get as far as pvcreate. Afterwards, I am unable to
create a visible vg. By that I mean, I receive no error when I issue
vgcreate, but I am unable to vgdisplay the new vg.
This is on SLES9/SN2 with two module SGI A350 and using two FC paths.
I had not used the -v or -d option prior to this, no. But, here is the
information:

All of the <snip> are the "Found duplicate PV" UUID lines. This system
has two FC HBA's, one each connected to a FC switch, which has two
ISL's, and then each switch has two paths to the TP9500 controllers.
I am guessing, guessing since this is my first time to use LVM, that the
output from pvdisplay showing "Allocatable NO" is bad. I have
tried pvchange, but it seg faults.
thanks
