New LUN on MSA1000, An alternate path on HPUX?

[Juan Manuel López]

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:

AND HOW THE O.S see THIS DISK:

disk 88 0/12/0/0.1.0.0.0.0.0 sdisk CLAIMED DEVICE COMPAQ MSA1000 VOLUME
/dev/dsk/c13t0d0 /dev/rdsk/c13t0d0

disk 71 0/12/0/0.1.0.0.0.0.1 sdisk CLAIMED DEVICE COMPAQ MSA1000 VOLUME
/dev/dsk/c13t0d1 /dev/rdsk/c13t0d1

Ussing SAM, I see disk 71 like alternate path of disk 88.
Any suggestion ?

Juanma.

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
Juanma.
