I like 3 vritual host machine, each virtual machine is assigned disks called: HP Virtual LVDisk and HP Virtual Disk
What is the difference between each of them?
These disks are assigned by the Host? They are internal disks the server?
Solved! Go to Solution.

Re: Virtual Machine (Disk)
With HPVM the guest system does not see the physical disks assigned to the host.
run ioscan -fncdisk to see.
The host system as you guess, presents disks to the virtual system which does not have direct access to the hardware.

Re: Virtual Machine (Disk)
Very interesting output.
SERVER:/> ioscan -C disk
H/W Path Class Description
================================================
0/0/0/0.0.0 disk HP Virtual LvDisk
0/0/0/0.1.0 disk HP Virtual LvDisk
0/0/0/0.2.0 disk HP Virtual LvDisk
0/0/0/0.5.0 disk HP Virtual Disk
0/0/0/0.6.0 disk HP Virtual Disk
0/0/0/0.7.0 disk HP Virtual Disk
0/0/0/0.8.0 disk HP Virtual LvDisk
0/0/0/0.9.0 disk HP Virtual LvDisk
0/0/4/0.0.0 disk HP Virtual LvDisk
0/0/4/0.1.0 disk HP Virtual LvDisk
0/0/4/0.2.0 disk HP Virtual LvDisk
The difference here appears to be some of the disks are configured with LVM, some not.
They are all vitrutal and should be usable on the system.
insf -C disk (not needed on 11.31 I'm told)
insf -e

Run the command ioscan as follows to show more details on these disk devices:
# ioscan -fnkC disk

SolutionThe insf command installs special files in the devices directory,
normally /dev. If required, insf creates any subdirectories that are
defined for the resulting special file. Both the legacy and
persistent device special files (see intro(7)) are created, unless
specified.
You can't talk to disk without device files. The commands I gave you improve your chances of actually doing something with the disk.
LVM - Logical volume manager. The disk is managed by LVM and logical disk volumes can be written to it. Versus whole disk, which two of the disks appear to be.
The LVM disks have been initialized with the pvcreate command and are probably already members of a volume group, which is a bunch of disks, theoretically put in a volume group for a common purpose.
