HP-UX PV-LUN association for FC60

HP-UX PV-LUN association for FC60

I'm trying to find which of the five identically sized LUNs is which while direct (fibre) connected to an L2000-44 with 11i. I followed the EVA thread but diskinfo just tells me it's a A5277A device.
How can I tell which is which ?
Thanks,
Damian

Re: HP-UX PV-LUN association for FC60

Well, actually the advice in the previous thread probably does work in that I actually have LUNs 0, 1, 2, 3 and 6 connected and mounted and the following is the output of ioscan -funC disk:

disk 27 0/3/0/0.8.0.5.0.0.0 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t0d0 /dev/rdsk/c7t0d0
disk 28 0/3/0/0.8.0.5.0.0.1 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t0d1 /dev/rdsk/c7t0d1
disk 29 0/3/0/0.8.0.5.0.0.2 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t0d2 /dev/rdsk/c7t0d2
disk 30 0/3/0/0.8.0.5.0.0.3 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t0d3 /dev/rdsk/c7t0d3
disk 34 0/3/0/0.8.0.5.0.0.4 sdisk NO_HW DEVICE HP A5277A
/dev/dsk/c7t0d4 /dev/rdsk/c7t0d4
disk 37 0/3/0/0.8.0.5.0.0.6 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t0d6 /dev/rdsk/c7t0d6
disk 31 0/3/0/0.8.0.5.0.1.0 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t1d0 /dev/rdsk/c7t1d0
disk 32 0/3/0/0.8.0.5.0.2.0 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t2d0 /dev/rdsk/c7t2d0
disk 33 0/3/0/0.8.0.5.0.3.0 sdisk CLAIMED DEVICE HP A5277A
/dev/dsk/c7t3d0 /dev/rdsk/c7t3d0

I suppose I'm confused by the 3 extra entries for c7t1d0, c7t2do and c7t3d0 for which I have nothing connected (and no disks on the FC60 in a LUN).

Re: HP-UX PV-LUN association for FC60

So, the 3 extra entries were old special files which needed removing.

I'd like to thank everyone for their replies.

EVA is a pain :). You could probably tell with securpath. Else you need to try to see if you can extract the wwn of the disks out of the extended hex info in a verbose diskinfo. If that fails do a extended scsi inq that you would write in c code and pick through the hex data for the wwns. Im working on testing some of this stuff but it will be a while because its tinkering for fun LOL. Drop a line in the forum if you find a better way.

Jeff,

This isn't an EVA - its a FC60.
