we are planning to buy a new storage system for attaching it to a SAN with Windows and HPUX Systems. Has anyone implemented the EVA into an HPUX environment? if yes, does it work properly? did you do any testing for compatibility before attaching to the SAN?
Do you have any testing scenarious?
Any informations are welcome.
Solved! Go to Solution.

Re: EVA - HPUX Compatibility
You will need SecurePath software (it's required with EVA).
If you're looking for someone who's done this already, well, it's a fairly new product (HP-UX cluster certified in late December 2002), so I'm sure deployments are still somewhat limited.
Good luck,
Vince

SolutionWe ordered the EVA (as well as some HP-UX machines) and HP comes to implement this.
According to the salesreps AND the engineers this should be straightforward.
I 'll keep you informed if you want to.

Re: EVA - HPUX Compatibility
We purchased an EVA about a month before HPUX support came online. (The first try at supporting it. We got our EVA online, then Compaq pulled back...) Until about 3 days ago we had only HPUX attached to the SAN. We use the 2GB fibre cards for the HPUX machines. We have both HPUX 11.0 and 11i attached.
The SAN connection works as it should. If you have 2 HBA's, the failover provided by the EVA drivers works very, very well. (We tested HW failures from the card to the disk. The failover works very well.) We get a very fast read/write rates on the SAN. (We saw faster write rates to the SAN than to the internal disks.)
As far as testing, before we made the SAN production, we simulated HW failures all the way back (Pulled the fibre, failed a switch, etc.) while writing to the SAN disks.
If you want more info, let me know.
Hope it helps
John

Re: EVA - HPUX Compatibility
thanks for the answers. We just got a EVA for testing for 4 weeks from HP. Did you test a enclosure failure on the EVA? we had some different answers from HP about enclosure failure, some said it works, some it won't work , or will work only under some specific configuration. friday we tried one of this specific configurations, 12 disks in one diskgroup ,and 6 enclosures, and it worked fine. the 18 disk in diskgroup , crashed the system--> no answer from hp till now.
then the secure path hpux, why do you need one? if you don't need load balancing, it should work with lvm, but it does not. secure path does not work with other software products on the same server like power path from emc or autopath, and this you can not guarantee in a big san, where every server could see every storage.

Re: EVA - HPUX Compatibility
No we did not do a enclosure failure test. As a matter of facts, we did not test much at all. Our building burned out, and we went to a new location. From there we ordered a complete serverroom. The SAN happened to be EVA.
SecurePAth: we use it for loadbalancing and for redundancy. We don't want to have SPOF's. In the old building I worked with Autoraid which had no Securepath, and it was fine too. The problem with that was, that after an igniet install, all the path's were default. (All primary's to the first path).

Re: EVA - HPUX Compatibility
I think it is just a matter of what the EVA people will support. They support their drivers, if you do not have their drivers, their ability to support your configuration is 'fuzzy'. You can use the secure path drivers even if you only have 1 HBA, you are still supported by Compaq, and should be able to take to the device file by everything else.
(Typing spmgr will show you all the options. It's a nice tool to see what's happening to your luns...)
Hope it helps
