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.

thanks
eric

Have you tried the vgcreate with the -v (for verbose) or -d (for debug) options? ----- Original Message ----- From: "Eric Wagar" <[email protected]>

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
eric
