On HP-UX clusters

[arkie]

Hi,

I am new to clusters.

There is an already configured 2-node cluster running on HP-UX 11iv1. I need some guidance on how to determine whether it is an active-passive or an active-active cluster.

Thanks!

easy.
Use cmviewcl to see which node a package lists as it's primary node.
If there is more than one package, and they list different primary nodes, you have an active-active set-up

Hi

a) are you run SG or VCS?

- ps -ef | grep -i cmcld
- ps -ef | grep -i had

b) For SG

- cmviewcl

Both nodes will be active and enabled, all packages will up and the package line will tell you what nodes its running on. For example:

PACKAGE STATUS STATE AUTO_RUN NODE
pkg up running enabled ftsys10 / ftsy11

Hi,

If it is serviceguard ,

#cmviewcl will tell you everything

:)

Hi,

# cmviewcl

CLUSTER STATUS
cseb up

NODE STATUS STATE
r3ci up running

PACKAGE STATUS STATE AUTO_RUN NODE
ciN11 up running enabled r3ci

NODE STATUS STATE
r3db up running

PACKAGE STATUS STATE AUTO_RUN NODE
dbN11 up running enabled r3db

# ps -ef|grep -i cmcld
root 4612 4609 0 Feb 18 ? 124:31 /usr/lbin/cmcld -m -n r3db -n r3ci
root 4818 4758 2 11:53:04 pts/ta 0:00 grep -i cmcld

# ps -ef|grep -i had
root 4821 4758 0 11:53:21 pts/ta 0:00 grep -i had

It means I have Serviceguard. And since each of the 2 nodes are running a different package (dbN11 in r3db & ciN11 in r3ci), can I assume this is active-active cluster.

Thanks rariasn for the useful link and all of you, but I am unable to assign any points here. The dropdown box is not appearing and each of your responses are only saying "unassigned". What could be the problem?

[S.N.S]

Yes, two packages on two nodes =Active Active Cluster as per normal definition

cmviewcl ---> for SG; the ps|grep o/p already shows cmcld - the main SG daemon running...

Points>>> I had the same problem before..

But now once I log in and check the question I submitted, I get the drop down - for IE, Firefox $ Chrome...
Just login again, I guess
