New LUN on MSA1000, An alternate path on HPUX?
Hi all.
I have added 4 new disks to my msa1000 enclosure.
I have created a new LUN raid5 and without more configuration I have discovered the new disk in HPUX machine.
The problem is that the new disk is recognized like an alternate path.
What I have to do to see the new disk like a diferent disk ?.
I show the MSA Details:

Re: New LUN on MSA1000, An alternate path on HPUX?
I have found a post with the same problem.
I also create a new vg and lv with the second lun, so SAM does not see this 2nd disk and see it like alternate disk of first disk of msa 1000.
Any suggestion ?
Thanks in advance
