LVM vs VxVM

Wow,
I was away on vacation and really didnt expect any reply to this. Anyway, what I ment by the "mad rush" was that it *seemed* to me (for a while at least) that HP wished to migrate away from LVM in favor of VxVM and that recently HP seems to have backed off from that position.
Any replys?

That was exactly my impression. HP initially seemed to be touting VxVM as the next "best" thing, but I've heard very little, if any, hype about it for the last year.

Hi:

I agree that the focus on VxVM as an LVM replacement seems to have dimmed somewhat. This may only reflect that the "first-announcement" fevor has died down. However, with the assimilation of Tru64 into HP-UX, I suspect that HP is going to reinvest in LVM, at least as one very viable alternative to VxVM. A recent thread offers some interesting observations:

There are also some other comments in this (old) thread which dates to the earlier days of VxVM. In fact, I think this thread is a spin-off of it:

I believe that Veritas has damaged their image with their backup products to the point that the other products have come under suspicion.

In My opinion, Veritas tech support is worse than Legato's tech support.

About 3 years ago I took the New Features and Functionality of 11.i course. At that point HP was certainly pushing VxVM.
I had worked with VxVM on Sequent systems and while it certainly allowed you to get more granular when setting things up, it more often than not came back to bite us later. We spent too much time moving applications around and resizing file systems and volumes, mostly bad planning on the part of our system architects. It was tedious to find or make available space.
It's mostly a matter of comfort. LVM does what I need it to do and it's easy to work with. Mostly from familiarity. I had no need to move to VxVM. I'm frankly relieved that HP has seemed to pull back from the VxVM push.
On the other hand it's nice to have the option. If you are already familiar, and comfortable with VxVM, need some specific functionality, can get the money allocated, it's a good option.

As noted in other threads.

The customers like LVM. It will stay.

I among others will not consider migration until all LVM features are build into the VxVM product, including bootable root disks.

Its going to be a while, and there will be adequate warning. I agree, the initial HP enthusiasm has waned.
