OpenVMS virtual machines and cluster
I tried to put two OpenVMS virtual guests in cluster. I want to use a quorum disk in cluster. I can present (using HPVM) quorum disk to both servers, but I can only boot one of them. On other server I got a message that disk (quorum disk) is already used. How to solve this problem?

Re: OpenVMS virtual machines and cluster
I doubt many have.
I would try to engage support for hand holding as soon as possible in this situation
The June-2010 OpenVMS Cluster Manual only mentions HPVM guests are support. That's it.
The OpenVMS on HPVM guest cookbook only gets the very basic going, leaving out any cluster hints. Still, you checked that right?
http://h71000.www7.hp.com/openvmsft/hpvm/integrityvm_cookbook.pdf
Which version of HPVM. 4.3 ?
Some useful OpenVMS words in:
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02752979/c02752979.pdf
Service Guard in play? This whitepaper is interesting:
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02015679/c02015679.pdf
Anyway,
Sounds like you defined 2 separate system disks. Correct?
What is the backing for the quorum disk?
I don't think shared disks can be file backed but need to map to physical disks.
What hpvmmodify command was used to define the (quorum)
>> On other server I got a message that disk (quorum disk) is already used.
When does that appear? Can you copy & paste the exact message and a few lines leading up to that?
Hope this helps some,
Hein

Re: OpenVMS virtual machines and cluster
>>>
OpenVMS on HPVM can't have shared storage
<<<
Huh?????
For 0ver 25 years I have lived in the conviction that shared storage is __THE__ big advantage of (VMS-)clustering, and now HP starts offering "clustering" WITHOUT it??
Even Tru64 has(/had) a reasonable implementation.
Is HP trying to downgrade VMS to to the level of M$ or lesser NIXes?
Maybe soon I will start beging GLAD to be layed off.....
fwiw
Proost.
Have one on me.

Re: OpenVMS virtual machines and cluster
Can you expand on your comment??
Are you saying that HPVM Guests (OpenVMS) can only share storage if that storage is "served" from a physical server that is a cluster member??
???

That statement certainly needs some amplification. I *suspect* that what Ian means is that shared storage must be MSCP-served; that only a single HPVM gust cluster member may have direct access to any one volume.
Ian?

Re: OpenVMS virtual machines and cluster
I think I solved the problem. The sollution is described in capture 6.1.3.3 of HP Integrity Virtual Machines 4.3:
Installation, Configuration, and
Administration manual.
Here it is how it goes:
(I'm sharing disk /dev/rdisk/disk135 to servers IZUMT2 an IZUMT3)
# hpvmdevmgmt -l gdev:/dev/rdisk/disk135
/dev/rdisk/disk135:CONFIG=gdev,EXIST=YES,DEVTYPE=DISK,SHARE=NO:IZUMT2:0x01.0x002
# hpvmmodify -P IZUMT3 -a disk:avio_stor::disk:/dev/rdisk/disk135
# hpvmdevmgmt -l gdev:/dev/rdisk/disk135
/dev/rdisk/disk135:CONFIG=gdev,EXIST=YES,DEVTYPE=DISK,SHARE=NO:IZUMT2,IZUMT3:0x2
# hpvmdevmgmt -m gdev:/dev/rdisk/disk135:attr:SHARE=YES
# hpvmdevmgmt -l gdev:/dev/rdisk/disk135
/dev/rdisk/disk135:CONFIG=gdev,EXIST=YES,DEVTYPE=DISK,SHARE=YES:IZUMT2,IZUMT3:02
Regards
Domen
