SWCC Agent in TruCluster Environment
238 HSG80 ACS Solution Software V8.8 for Tru64 UNIX Installation and Configuration Guide
installing and configuring the SWCC agent on one cluster member configures the
agent using the storage information for that cluster member, but the configuration
information is then used on all cluster members.
It can be confusing if you run the SWCC agent on multiple cluster members and
those members do not have the same view of the storage. For example, assume
that you have used the selective storage presentation (SSP) feature
(ENABLE_ACCESS_PATH=, DISABLE_ACCESS_PATH=) to control which
hosts have access to disk units D8, D9, and D10. Further assume that cluster
member swiss can access these units, and that cluster member rye cannot. When
you use the hwmgr command on each member to look at the available devices,
member swiss can see units D8, D9, and D10, indicated by the user-assignable
identifier (IDENTIFIER=x), but member rye cannot:
# hostname
swiss.zk3.dec.com
# hwmgr -view devices
HWID: Device Name Mfg Model Location
