How to map disk from VMserver to VMguest ?

[Jerry_109]

Hello All,

I'm having trouble mapping a drive from VM Server(hohp244) to a VMguest (hovm235)? How do you tell which disk drive on the server is which drive on the VMguest (hovm235)?

hpvmstatus -P GuestName

hpvmdevmgmt -l gdev


If you use lv backingstores you can give the lvol a name like /dev/vg_guest1/disk1

Great, Thanks,:

Now I see "c3t0d5 & c3t0d6". Now do I map
these drive to "c0t0d0 & c0t1d0" on VMguest
hovm235?

root@hohp244[/root]
# hpvmdevmgmt -l gdev | grep 235
vswitch3:CONFIG=gdev,EXIST=YES,DEVTYPE=SWITCH,SHARE=YES:hovm234,hovm235,hovm237:WWID_NULL

your simplest way is to use the VMM or Virtual Machine Manager, this will give you a graphical representation for your VM's, networking, storage etc.

Other than that, use hpvmstatus -Vp
In the output you will get information something like the following:
[Storage Interface Details]
Guest Physical
Device Adaptor Bus Dev Ftn Tgt Lun Storage Device
======= ========== === === === === === ========= =======
disk scsi 0 1 0 0 0 file /var/vmdisks/vm1
disk scsi 0 1 0 2 0 disk /dev/rdsk/c4t10d0

Notice the Bus/Dev/Ftn/Tgt/Lun info.
In this case, if the guest OS were HP-UX, you would see two discs, /dev/dsk/c0t0d0 and /dev/dsk/c0t2d0

So use the hpvmstatus -Vp command, and work out your disk from there

looks like I do not have VMM:

from the hpvmdevmgmt cmd the (2) drives have a unique ID :
"00a1-0000" & "004a-0000" ? is there a way to map this to "c0t0d0" or "c0t1d0" on hovm235?

found great command that maps VMserver disk
to VMguest disk :
