SFWHA 5.0 and disk based communications

 
Hi,

I'm working with a two node campus cluster, using SFWHA 5.0 over
Windows 2000 Server.

A few days ago, a failure on a core router cut both heartbeats and the
production network links, resulting in a split brain. The SAN links
were intact.

I've been thinking about adding IO Fencing or disk heartbeats to the
cluster, but I can't find any documentation about how to
configure them.

Besides that, after a little digging in the 'bin' directory of Cluster
Server, I found that the DiskRes agent doesn't exist, however, there
is a DiskRes.xml file inside the 'Cluster Manager\attrpool\W2K\default' directory.

That made me think that disk based comms might be not supported on Windows.

So, are disk reservations, disk heartbeats or IO Fencing officially supported on the
Windows platform?

Thanks

  • Hi,
     
    I tend to work on the Solaris platform but I do know that Symantec very recently dropped support for disk heartbeats.
     
    This was discussed on a VCS 5.0 course I attend a few weeks ago and the instructor confirmed that symantec had dropped disk heartbeats in favour of I/O Fencing.
     
    Suspect it would be the same for the windows platform.
