Alpha V7.1-2
Alpha V6.2
VAX V6.2
Alpha V7.2-1
As anyone any knowledge about a cluster combination as above and then say moving the V7.2-1 Node to V7.3-1 or V7.3-2? I know this is not a supported configuration but will it work?
Solved! Go to Solution.

Re: VMS versions in a cluster
as long as the cluster version is the same, cluster communication should work.
$ ANAL/SYS
SDA> exa clu$gb_cluver
CLU$GB_CLUVER: 00000000.00000006 "........"
( VAX V6.2 has CLUVER = 6 - same as Alpha or I64 E8.2)
Happy clustering ;-)
Volker.

Re: VMS versions in a cluster
I know this is not a supported configuration but will it work?
For VMS, generally spoken "unsupported" is NOT equal to "won't work". For instance, a cluster of Itanium and VAX is "unsupported", but I've seen this type of clusters - even a IA64-AXP-VAX one - at HP-events.
In case it doesn't work, you ARE in trouble since that's what "unsupported" means: "It will (eventually) work; if it does - fine. If is doesn't - you shouldn't have tried in the first place" (Just my interpretation)
So: Simply try it out. Chances are it'll just work.
BUT BEWARE: This may be true for VMS itself (and clustering in particular) but it does not mean that your business software will be happy with this configuration.

Re: VMS versions in a cluster
Volker gave the way of checking that the fundemental cluster comms will work. This does not mean everything will work. Hoever the cluster I have has been running for quite a while and seems to be fine.

Re: VMS versions in a cluster
We have seen patches for V6.2 to be able to cope with port allocation classes in V7.1 and lock manager changes, for example.

Re: VMS versions in a cluster
Nigel,
Pick up the 6.2 patches, and read thu the release notes.
In the 6.2 time frame there were some patches that needed to be installed BEFORE a mixed version V6 + V7 were possible.
I would give you the specific patch names, but alas, my Prod Hist only reports the amalgamated UPDATE patch, which we apparently installed shortly before (ie, in preparation of) the VMS upgrade.
IIRC, there were some Shadowing issues, and some DECnet V issues (heh, it's been over 5 years, and this IS from human memory, so check it before you take my word for it!)
Success
Jan
