Service Guard and Trusted System

[Thamm]

Hi,
we are planing to switch our 11.0 metrocluster (3 N-class servers; XP-512) to a trusted system.
Service-Guard 11.13

Does anybody have bad/good experiences with this configuration?

Regards,
Stefan.

Service Guard works very well with Trusted system without any problem

Hi

we have several clusters all on trusted systems and there are no special problems with this configuration.

I went on Trusted System with Service Guard and without Service Guard, and never had a problem.

Hi Stefan,

I'd advise that you have at least 2 root windows open when you convert so that you can leave one alone when testing root login. It can be a real pain if root's PW is mangled & you can't login.
Having the other window will allow a root PW change opportunity.
Otherwise should be no problem....

My 2 cents,
Jeff

Yeah, there should not be any problem. We have a trusted and a non-trusted node in a two node cluster.

If you really see, cluster will need need to run certain scripts, needs VG involvment, network cards and some monitoring stuff, remsh (or cmnodelist) . So, making system trusted should not affect Cluster as long as your trusted system conversion goes okay and all users are okay.

hope this helps...

One thing to remember - it's all OK to say that SG works OK in a trusted cluster, but what about the application you're tyring to run on it? I've had numerous problems attempting to convert systems to C2 only to find that although the system itself was OK, the applications running on it were far from OK. Half of the trouble is that vendors don't cater for the low level code changes (for example, if I remember correctly password entries are retrieved using getpwent - this changes to getprpwent when converted to C2 and a number of vendors don't cater for this).

Good Luck.
