Is RAID5 Possible with LVM? Is LVM Mirroring now Free in 11.31?
2. LVM Mirroring -- is it now "free" in 11.31 or is MirrorDisk/UX still required? Just did a fresh install on an Itanic rx2660 and am surprised to see already some of the changes in v3.0.
Thanks.

2. MirrorDisk is still required to do mirroring. As to the FREE question -- No not really. If you buy the Enterprise Operating Environment (EOE) or higher level of the HP-UX OS, then Mirror Disk is included.

So much to lose, so little to gain!
http://www.miracleas.com/BAARF/RAID5_versus_RAID10.txt
You may want to review and consider the Oracle ASM. I've been highly sceptical about that, having had fine experiences and Tru64 LSM, HPUX LVM, Storage Controller based redundancy (EVA, HSx, XP,...) and RAW devices. My kneejerk reaction was to let Oracle to DB stuff and let the OS provision the storage, each doing best what they are good at. But if you think about it, Oracle does know more about how it is using the storage and how it might be using that better than the OS will ever know. It has an unfair advantage in that space (sic) which perhaps one should exploit, not resist. ASM does seem to deliver performance and availability, and it does seem to become accepted.
Hope this helps some,

Because this is a rx2660 you may consider to use hardware RAID. Depending on the installed controller, you can create several RAID levels.
Hope this helps!

RAID5 native? No.
You can however white a script that does small lvextend commands and rotates them among the a group of disks.
This can give you the protection and feel of Raid 5.
As far as mirror/ux goes, its still a product you have to pay for.

And for 11iV3 I believe that LVM mirroring is now included with the Enterprise OE, or available for free even.

Re: Is RAID5 Possible with LVM? Is LVM Mirroring now Free in 11.31?
Wow.. had I known.
Anyways I simply used base VxVM -- OS rooted and mirrored.
I don't think this little Itanic Turby got a SMART Array Controller. It would have made life a lot better.
As for the rest of the disks... we'll be waiting on a license transfer of full VxVM...
Man v3.0 is vastly changed but "accomodates" the skills sets of the pre v3.0 Admin.
Nice indeed.. but IMHO SOlaris 10 and the upcoming AIX 6 are still ahead...

#2 is another question. I went to a local HP sponsored seminar about the new 11.31 and was told HP will not charge for mirroring. When? For what O/S version exactly? Don't know. Just what I was told by an HP person. More clarification would be real nice though.

Re: Is RAID5 Possible with LVM? Is LVM Mirroring now Free in 11.31?
I think in a typical setup nowadays you have a server with a hardware RAID connected (SAN).
For highly availability you can still mirror between different hardware RAIDs.
The server will have a set of 2 internal disks for mirrored boot disks. A third disk could be used for DRD.
If you have more internal disks (rx2660/rx3600/rx6600) you can use a hardware RAID like the P400 - this would not consume CPU power to calculate the RAID.
Hope this helps!

Torsten.

LVM mirroring is not free - included with EOE and MCOE...
There is talk that in 11iv4, lvm mirroring for just the root disk may be included...
v3 rocks - Persistent DSF is great!

Re: Is RAID5 Possible with LVM? Is LVM Mirroring now Free in 11.31?
As Duncan has already said, On Integrity servers, MirrorDisk IS free providing you ask for it. If you don't it doesn't appear.
We have just purchased and installed 2 Integrity rx2660 servers and requested MirrorDisk/UX and were not charged. I queried this and that is what happens - it is free - if nowhere else, certainly in the UK.
regards,
Mike.

I could tell you the real reason they have made the change, but I think it's NDA right now. (Although the marketing answer is that it's "value add to you!")

Like I said, thats cos its free of charge with new FOE orders *if* you request it. If this system was purchased before it was free of charge, or Mirrordisk wasn't requested with it, then you don't get it - it's still not in the FOE bundle.

Re: Is RAID5 Possible with LVM? Is LVM Mirroring now Free in 11.31?
"On new Integrity servers with dual core processors we can quote a "no cost" mirror-ux, this is the full version and it carries no software or support costs at least for the first three years."
Another thought I have is, Base VxVM does include root disk mirroring - means converting from lvm to VxVM.
