(I apologize if this double-posts, long story) Hello all. I have what I hope are a few simple questions on RHEL 5.2 clustering using HP DL380 hardware. Long story short, we have several HP DL380-G4s that we are trying to set up in a test cluster but we do not have any of the obvious fencing options available to us. ILO fencing does not seem to be an option because our standards dictate ILO be on an out-of-band network. We have SCSI fencing in place but I'm not convinced it is working properly nor that it is reliable. I hope to find funding to get an APC Masterswitch in place but that is not our standard so I need approval. In the meantime, can anyone offer any answers on the following questions? 1) Are TripLite or other power controllers supported aside from what is on the hardware list? (http://www.redhat.com/cluster_suite/hardware/) 2) Is there a reliable way to change the SAN switch fencing controls to use SNMP (preferred) or perhaps SSH? According to 'man fence_brocade' the system uses telnet. An interactive login to a 256-port switch is bad enough, but doing so over an unencrypted telnet session just isn't going to fly! I would think this would be a relatively trivial change to the script. Has anyone done something like it? 3) Does anyone have any experience clustering DL380s and have recommended Primary & Secondary fencing methods or advice they would be willing to share? 4) Is anyone out there using only 1 fencing method with GFS filesystems in Production environment?
