HP Instant Capacity Version 10.x Release Notes (5900-2062, December 2011)

Automatic multi-homing not supported
GiCAP does not support automatic multi-homing (multiple NICs and IPs for a host). A member is
always contacted using the hostname (or a list of hostnames) provided when it is added to the
group. A member always communicates with the Group Manager through its hostname. If the
Group Manager is not reachable through that hostname by a given member, the member is unable
to participate in the group.
Considerations when upgrading hardware on a Group Manager
If you upgrade the hardware on a Group Manager system, you must preserve and restore the
UUID and the partition information on the system.
If AGM is unable to get status of SGM it shows that as Active GM
If AGM is unable to collect status of SGM due to any reason (network is not reachable or cimserver
is down or cimserver is not responding within the given time), AGM assume that SGM is also an
active GM. And this can be very well a case of split group. Verify if cimserver on SGM is working
fine, and whether it is reachable from AGM, if this problem persists.
