Support information
• Red Hat GFS2 which is an enhanced version of the Red Hat GFS is currently released as
technology preview in RHEL5 update 1 i.e., not fully supported by Red Hat. Hence
Serviceguard will currently support Red Hat GFS and not Red Hat GFS2
• XEN/VMware guests with GFS as Serviceguard nodes are not supported.
• HP Integrity servers are not yet supported. If they are supported in the future, only those
that support iLO fencing will be allowed.
