Define VxVM Version in Ignite

Hi

I am using Ignite C.6.8.152 and am building HP-UX 11.23 with Veritas Volume Manager 4.1

When I perform my build during the Configure Disks step I get the following:

* Configure_Disks: Begin

* Will install B.11.23 onto this system.
* Starting VxVM. Target version: 3.5.
* Enabling VxVM.
* Creating VxVM Disk Group "rootdg". Target version: 3.5.

I have a root disk configuration file defining my root disk as:

volume_group "rootdg" {
usage=VxVM
......

My core OS depot only contains 4.1 volume manager which build successfully, but for completeness I'd like to find out if there is a setting to define the target volume manager version as 4.1

Many thanks
Chris

Re: Define VxVM Version in Ignite

Hi Chris,

Sounds like a bug!

You could try the latest Ignite version (6.9.x)

Hi Robert-Jan

I've upgraded Ignite to C.6.9.150 and the same problem occurs.

Thanks

Hi Chris,

I would call HP support and open a software call.

Re: Define VxVM Version in Ignite

I find these concepts about VxVM/VxFs to be a bit confusing and I get them easily confused. Here's a note I worked up that might help:

---------------

In the world of disk storage, we have:

- VxVM (the volume manager)
- VxFS (the filesystem)

Within each of these, there are 2 concepts:

- The product version of the software
- In VxVM this is the release version
- In VxFS this is the release version
- The layout version of the data
- In VxVM, this is the "Disk Group Version"
- In VxFS, this is the "Disk Layout Version (DLV)"


VxVM:
=====
VxVM is a storage management tool which takes a collection of physical storage devices such as disks) and "virtualizes" them into virtual "volumes". While these volumes are analogous to "disks", any given volume could span more than one storage device (i.e. there does not have to be a 1-to-1 relationship).

This product removes the physical limitations of disk storage so you can configure, share, manage, and optimize storage I/O performance online without interrupting data availability. It also provides online storage management tools to which should help reduce downtime.

For VxVM on B.11.23 we currently have 3.5, 4.1 or 5.0 (this is the product version). With the coming of B.11.31, we will have version 4.1 only. Product version 5.0 on B.11.31 should be available at a later date.

For "Disk Group Version", we can have 60, 90, 120 or 140 (see vxdg(1m) on a system with product version 4.1 or greater for more details). Note summary table:

product supports these
version Disk Group Versions
----------- -----------------------------
3.5 60, 90
4.1 60, 90, 120
5.0 60, 90, 120, 140


VxFS:
=====
Any one given VxVM volume can be formatted with a filesystem (again, analogous to the concept of formatting a physical disk). VxFS is a particular filesystem type (or format) that can used on a volume.

For VxFS, we can have a product version of 3.5, 4.1 or 5.0 (currently). For "Disk Layout Version", we can have 4, 5, 6, or 7 (see vxupgrade(1m) on a system with product version 4.1 or greater for more details).

product supports these
version Disk Layout Versions
----------- -----------------------------
3.5 4, 5*
4.1 4, 5, 6*
5.0 4, 5, 6, 7*

* - The default "Disk Layout Version" for the product version.


NOTE: Any "boot volume" (such as /stand) must be defined as "Disk Layout
Version" 5 (i.e. others are not supported).

NOTE: For more information on VxVM, see:
http://docs.hp.com/en/5991-5511/5991-5511.pdf

What could possibly go wrong?
