We read from Red Hat Cluster Suite doc, we need Remote Supervisor Adapter II as power fencing device and according to IBM RedBook, x3850 M2 and x3950 M2 have the RSA II service processor as a standard component.
If we don't have an extra network port, is it possible to set up RedHat Linux clustering using RSA II?
Can RSA II be used as power fencing device (& what's power fencing device?)
Kindly give as much details as possible as we're green to both clustering & IBM hardware
