Do you know a command for to retrieve this information?

Thanks in advance

Hi Andrea:

Since LVM is part of the HP-UX core components, I don't believe that there is any "version" other than patches that are periodically issued against it.

Regards!

Andrea,
and if you are after the VxFS DISK LAYOUT:
fstyp -v /dev/vgxx/lvolyy

Example:
# fstyp -v /dev/vg02/lvol02
vxfs
version: 4
f_bsize: 8192
f_frsize: 1024
.
.
.

Hi,

Thanks for your help but I have some doubt.

James said that LVM is part of the HP-UX core components so if I run swlist -l product |grep -i lvm I have the same HP-UX version of LVM version.

LVM B.11.11 LVM

The command fstyp -v /dev/vg02/lvol02 is good for retrieve the Veritas File System. is not same of the LVM?

So it seems that is not possible retrive the LVM version but it is part of the HP-UX core components.

is it right?

Thank a lot
Andrea.

Andrea,
correct. LVM 'version' is the version of the OS + relevant patches.

It's just sometimes people get confused between LVM and Vxfs disk layout when they ask for version numbers.

Hi (again) Andrea:

> The command fstyp -v /dev/vg02/lvol02 is good for retrieve the Veritas File System. is not same of the LVM?

That is correct. The Veritas File System layout version is a version of a *filesystem*. LVM is a disk volume management subsystem. A filesystem is a structure that resides *within* a logical volume. In HP-UX you commonly have VxFS and HFS filesystems. The older HFS type is still used for the '/stand' mountpoint.

That is correct.
