The group manager uses several standards when it groups PMs for a bulk
action. For example, when the SRC broadcast loads to nodes, the group
manager can use the following:
• a group of PMs with the same node type
• a group of PMs with the same load file name
• a group of PMs with the same loading method
How to group series II XMS-based PMs
The group manager uses the following standards when it groups series II
XPMs together for broadcast loading:
• the load file name
• the CMR (class modem resource) file name
• the presence of 6X45BA or higher controller cards
For example, two XPMs can have the same load file name and have
NT6X45BA controller cards, but have different CMR file names. The group
manager puts these two XPMs in different groups.
The XPMs that cannot be in the same group with other XPM units for
broadcast loading are single-loaded. The XPMs are single-loaded when the
XPM units do not have the hardware to support broadcast loading. The XPMs
are also single-loaded when the XPMs cannot be in a group with other units
during dynamic grouping. The group manager only groups the XPMs that
have NT6X45BA or higher controller cards. The XPMs that do not have
NT6X45BA or higher controller cards are not in the same group as other
XPMs. This condition occur even if the other XPMs have the same load files.
The SRC continues to coordinate single loading for purposes of concurrency
management.
Static and dynamic groups
You can identify PMs in the same group from datafill. The datafill specifies
the load file names and hardware configurations of the PMs. The system
maintains these static groups automatically over time as the datafill changes.
During recovery, the SRC forms dynamic groups from the subgroups based on
which elements require recovery and availability of resources to perform the
recovery.
Broadcast loading
Broadcast loading is a bulk action. Broadcast loading can operate on more
than one PM at the same time. To save time, the SRC performs an action on a
group of PMs instead of many separate PMs.
Automatic broadcast loading sends a request to load software to several PMs
at the same time.
