Veritas Cluster Server on HPUX 11 and HPUX11i

[Freddie Valdez_1]

We're trying to implement Veritas Cluster Server for our HP NClass servers.

One of the server (A) runs HPUX B.11.00 and the other server (B) runs HPUX B.11.11.

We are running production environments on both servers and we plan to implement
two-way failover across these two servers. In other words, (A) will be primary and (B) its
failover, and (B) also primary and (A) its failover. Everything is almost identical, except
for the HPUX release, (A) is HPUX 11 while (B) is HPUX 11i.

Our observations:

a. we can create filesystems on the primary and have them exported and mounted on the failover
without trouble, that is, from HPUX 11 to HPUX 11i.

b. However, filesystems created on (B) that we require to be exported and mounted
on (A) are coming up with mounting errors as captured below, that is from HPUX 11i to HPUX 11.

ServerA:/etc/lvmsave # mount -Fvxfs -o largefiles /dev/vgbfre1/lvol1 /bfree1

mount - unrecognized vxfs version number

Server B: has not issue mounting volumes
from server A:

questions:

is there any workaround aside from upgrading
(A) to HPUX 11i, or downgrading (B) to HPUX 11.

appreciate all the inputs from the experts.

thanks.

I don't think mixed OS's in a cluster is supported. They both have to be 11 or 11i.

your problem is due to 11i using a default version of jfs that is newer than the default used in 11.00
11i is version 4 by efault
do
fstyp /dev/vgbfre1/lvol1
You would have to ensure that the 11.00 system has JFS 3.3 installed. or just create all lvols/file systems on the 11.00 node.

Thanks to Martin and Melvyn.

We're going to apply two cumulative patches on our HPUX 11 to make both jfs compatible with the 4 layout in the 11i.

Another related issue I'd like to ask anyone who's done clustering with Veritas Cluster Server (VCS).

We're told by Veritas that we cannot purchase individual support say, for only VCS, if we bought the entire foundation suite, with Oracle database edition (although we're not using database edition to start with).

They confirmed that since we bought the entire foundation suite (by mistake), we can get support only by purchasing entire technical support package for
foundation suite, and not on selected components only.

We're considering of going back to MCSG if it's going to be more expensive with VCS support.

Any similar experience will be greatly appreciated.
