mixed architectures

[John Maki]

Is there any problem with mixing architectures in serviceguard? For example, one node is a DL380 running 32-bit Redhat and the other is a DL385 running 64-bit Redhat?

Shalom,

There is probably a big problem doing that. If both systems have a 32 bit install, you are fine. If one system has a 64 bit OS install I don't think serviceguard is going to work right.

My experience with HP-UX is that the OS and SG version must match, and the SG versions for 64 bit and 32 bit Linux are probably not the same.

Thanks - that would explain the problems I've been seeing. I can create a cluster with 2 nodes of different architectures and start each node, but if I try to modify the cluster the 32 bit node fails. I'll just split out the 32 bit servers into their own cluster.

[Serviceguard for Linux]

Steven is correct. Except during rolling upgrades, Serviceguard for Linux clusters are only supported when the same version of the OS is running on all servers. "Version" includes the architecture version.

During a rolling upgrade the OS has to be from the same vendor and be for teh same architecture.

Hi,

Mixed Hardware architecture is not supported on Linux.

On HP-UX

Beginning with the 11iv2 September 2004 HP-UX release, Serviceguard will support mixed clusters containing both HP 9000 and HP Integrity Servers. This requires that all nodes in the cluster are running the 11iv2 September 2004 release (or later) with Serviceguard A.11.16 or later. It is not supported to have a cluster that contains nodes running both HP-UX 11iv1 and 11iv2. All nodes must be running the same Serviceguard revision. SGeRAC clusters cannot contain a mix of of HP 9000 and Integrity servers, since Oracle RAC requires a single processor architecture per cluster.
