Re: best way to make lv with 3 500G luns

I think you are on the right track... Your PV's don't look right but I am not familiar with PV's on SCSI devs. Using the -v and -d options have helped me a lot!!!

Good luck!!

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

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: assault /home/ericwa# pvcreate /dev/scsi/sdh8-0c0i0l9;pvcreate /dev/scsi/sdh8-0c0i1l8;pvcreate /dev/scsi/sdh5-0c0i1l10

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
