VxVM and vg00

[Stephanie Nicholls]

Hi Guys

Im looking for a black and white answer *grin*

We are considering buying another L class, running HPUX 11.00, for a number of reasons we are also looking at Veritas Volume Manager, what I need to know is do I still need to buy MirrorDisk/UX to mirror my root disk or can VxVM do this for me??

Everything I have read so far indicates that vg00 must still be a LVM volume group which in my mind says I need Mirror/UX

Thanks

Steph

If you want to mirror vg00, you'll need to purchase MirrorDisk/UX as well as Advanced VxVM since mirroring is an extra cost product for both volume managers.

Thanks Bill.

Hello,

As of 09/02 (September 2002) CDs, you now CAN install HP/UX on VxVM. I've tried it with success!

HTH,

hello,

Vincent (farrugia) was right, still HP-UX september 2002,
there is no need to use another disk for VxVM "rootdg", you 'll need to choose this solution at the install time.
You could also use LVM with this configuration!.
After the installation completion, a "bdf" looks like:

Filesystem kbytes used avail %used Mounted on
/dev/vx/dsk/rootdg/rootvol
204800 101800 102296 50% /

With VxVM the mirroring of root disk only need a command line:

/etc/vx/bin/vxrootmir ???v ???b ???R c5t2d1 (for example)

Best regards

Hi,
Abad is right. There is no separate license required for
mirroring "only" rootdg. The Base VxVM is enough. You need
separate mirror license for mirroring dg's other than rootdg.

When you say September 2002 CD's is that for HPUX11.00 as well as HPUX 11i ?

Cheers

Nope only HPUX 11i

You can't boot off a vxVm volume(apologies to all for earlier vxfm typo).

I sense HP is backing away from vxVm becasue they have to pay Veritas for it and because they paid $18 Billion for Compaq and got a pretty good fs with True64 Unix.

that's from HP World.
