High Availability Cluster Multi-Processing (HACMP)
This section discussed HACMP supported levels, migration paths and
coexistence options.
Supported levels
While PSSP has no direct requirement for HACMP, if you install hardware that
requires PSSP 3.2, regardless of system partitioning, and you already use or are
planning to use HACMP, you must also install and use HACMP 4.3. HACMP 4.3
can be run on the SP nodes and SP-attached servers. HACMP/ES 4.3 can run
on the control workstation but prior levels can only run on nodes, not on
SP-attached servers and not on the control workstation.
HACMP has a dependency on the RSCT Group Services. The RSCT component
of PSSP is included in the HACMP install stack. The dependencies of HACMP
on AIX and PSSP are shown in Table D-5.
