Re: [Veritas-ha] LLT crossed links

Having multiple LLT links on the same VLAN/network can cause a variety of problems such as split-brain scenarios, inability to rejoin the cluster, and cluster failures. The heartbeats really need to be isolated from each other. Cheers, jf Sent by GoodLink (www.good.com) -Original

Right, that makes sense. The llttab manpage suggested to me that this wouldn't be a terrible thing to do, but I'm with you now. Thanks! Ceri On Tue, Feb 19, 2008 at 09:39:50AM -0700, Joshua Fielden wrote: One can't set up a successful cluster planning for the best case -- one has to plan

[Veritas-ha] LLT crossed links

2008-02-19 Thread Ceri Davies
I have a couple of clusters running Solaris 10, VCS 5. I'm running IPMP on my public links and I want to configure each public interface as a low-priority link. Since they're connected to the same VLAN, when I start LLT I get the following warning: llt: LLT WARNING V-14-1-10497 crossed links?

I disagree, as long as the SAP stuff is taken care of. 2 dedicated + 2 additional (even sharing a VLAN) is pretty good. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joshua Fielden Sent: Tuesday, February 19, 2008 11:40 AM To: Ceri Davies Cc:
