Tracing "disks" on guests to the corresponding LV on host?

[Doug O'Leary]

Hey;

Is there a foolproof method of identifying the LV on the host that corresponds to each PV on the guest system?  I'm pretty good at reasoning it out; however, there's one case that has me baffled.  

For instance: I'm trying to track down which PVs on the guest correspond to these 'disks' in the hpvmstatus output:

disk    avio_stor    0   0   0   0   0 lv        /dev/vgvmboot/rr3db21v2

disk    avio_stor    0   0   0   1   0 lv        /dev/vgvmboot/rr3db21v2_d1

disk    avio_stor    0   0   0   3   0 lv        /dev/vg00/rvgAD1db_d8

disk    avio_stor    0   2   0   5   0 lv        /dev/vg00/rvgAS1db_d8

disk    avio_stor    0   6   0   1   0 lv        /dev/vgvmboot/rr3db21v2_d2

The last one's pretty easy: 

disk     66  0/0/6/0.1.0   sdisk   CLAIMED     DEVICE       HP      Virtual LvDisk

                          /dev/dsk/c2t1d0   /dev/rdsk/c2t1d0

as the h/w path exacty matches the information in the storage interface section.  Most of the others were equally as obvious.  What's confusing me, though, is the one listed as tgt 3:

# ioscan -funC disk -H 0/0/0/0.3

Class     I  H/W Path     Driver S/W State   H/W Type     Description

=====================================================================

disk     23  0/0/0/0.3.0  sdisk   CLAIMED     DEVICE       HP      Virtual LvDisk

                         /dev/dsk/c0t3d0   /dev/rdsk/c0t3d0

disk     86  0/0/0/0.3.1  sdisk   CLAIMED     DEVICE       HP      Virtual LvDisk

                         /dev/dsk/c0t3d1   /dev/rdsk/c0t3d1

There are two disks listed on h/w address 0/0/0/0.3.  I assume it's the first one; however, I'd like a verifiable method of idnetifying that.  "I think that's it" doesn't sound good when talking to cients :)

Here's the entire storage section from the hpvmstatus.

If someone could give me the clue I'm missing, I'd appreciate it.

The thing is that the target>15 is not directly mappable to legacy io path.

See Admin manual 6.1.3.6 for mapping details.

The easiest way to achive what you are after is hpvmdevinfo command.

Hey;

Thanks for the reply.  I looked on both the host and a guest and I don't have that command installed.  I have an old version of HPIVM, though, so maybe that's it.

Could you show an example of what hpvmdevinfo displays?

Thanks.

Here's an hpvmdevinfo output from one of my Integrity VM v4.2 servers.  Unfortunately the text formatting in this window doesn't help much.  Trust me, in a wide-format terminal window, the output is much easier to read when the columns line up properly:
