Notification
initial-sync as part of an OPM session.
OPM (4) Open I/O The primary controller generates this notification prior to the
Conns transfer of I/O connection related data as part of initial-sync
during an OPM session.
OPM (5) Match This notification is generated by the primary controller prior
Peer Refs to transferring peer cross-reference ID data as part of initial-
sync during an OPM session.
OPM (6) Transfer This notification is generated by the primary controller prior
Data to transferring dynamic data as part of initial-sync during an
OPM session.
From this point forward, control is frozen on the primary
controller for up to 5 seconds (depending on the size of the
control strategy). Control is resumed following either the
switchover (upon completing OPM initial-sync) or on
abnormal termination of the OPM session.
OPM Session Upon the successful completion of OPM initial-sync, a
Complete switchover follows shortly after (<100 ms). This notification
is generated by the primary controller due to event
regeneration following the switchover into the primary
redundancy role and represents successful completion of
the controller OPM session.
OPM Partial Cold The default behavior when one or more blocks have not yet
Init implemented OPM support is to cold initialize the block(s).
Upon the successful completion of an OPM session, the
new primary controller sets the RDNOPMSTATUS
parameter to PartialColdInit and generates this notification to
indicate one or more blocks have been cold initialized. This
notification is generated only once regardless of how many
blocks were initialized. This notification represents
successful completion of the controller OPM session.
OPM Commanded The primary controller generates this notification when the
Abort Controller Migration Wizard commands the controller to
abort the current OPM session. This notification represents
unsuccessful OPM session termination.
OPM Create Block This notification is generated by the primary controller upon
Timeout timeout of OPM secondary checkpoint restore operation.
Secondary checkpoint restore timeout occurs if checkpoint
data is stalled for longer than 2 minutes. This notification
represents abnormal OPM session termination.
OPM Initial Sync This notification is generated by the primary controller when
timeout initial sync does not commence within 2 minutes following
the receipt of the Controller Migration Wizard command to
