1. Remote Management Controller Vendor. Select the Hewlett-Packard
for your Remote Management Controllers. By default, the item
“Vendor and type selection apply to all controllers for the cluster” is
checked. Remove the checkmark from this item if your Remote
Management Controllers are from different vendorsor if, in the case
of IBM Remote Management Controllers, some are associated with
IBM BladeCenter servers and others are not.
CAUTION: If you will be using IPMI as the fencing method, you
should be aware that only one IPMI session can be active at
a time. Clustered File System will fail to fence a server if
another IPMI session is already active on that server at the
time that the fencing attempt is made.
