(4) pairsplit -RS option
In the case of PAIR state (NO failure):
• Issues SwapSuspend to make a suspending state for consistency group
on each RCU
• Searches/commits a minimum matching point of the CTQ-Marker on RCU
via RCU (in other words, do Journal Restore with CTQ-Marker)
• Repeats above until detecting an EOM (End Of Marker) marked on MCU
on all RCU via RCU
• Issues End of Suspend to terminate a suspending state, after committed
with an EOM (End Of Marker) on all RCU
Exception: If an uncommitted state (that is, link failure) is detected while
executing its operation, then the operation of committing is aborted on
keeping current CTQ-Marker level, and a suspending state terminates with
detecting at least one EOM (End Of Marker).
In the case of Failure (PSUE/PSUS):
• Issues SwapSuspend to make a suspending state for consistency group
on each RCU
• Searches/commits a minimum matching point of the CTQ-Marker on RCU
via RCU (in other words, do Journal Restore with CTQ-Marker)
• Repeats above until detecting an EOM(End Of Marker) marked on all RCU
via RCU
• Issues End of Suspend to terminate a suspending state
(5) pairsplit -R option
In the case of PAIR state (NO failure):
• Issues Delete to make a deleting state for consistency group on each RCU
• Searches/commits a minimum matching point of the CTQ-Marker on RCU
via RCU (in other words, do Journal Restore with CTQ-Marker)
• Repeats above until detecting an EOM (End Of Marker) marked on MCU
on all RCU via RCU
• Issues End of Delete to terminate a deleting state, after committed with
an EOM (End Of Marker) on all RCU
Exception: If an uncommitted state (that is, link failure) is detected while
executing its operation, then the operation of committing is aborted on
keeping current CTQ-Marker level, and a deleting state terminates with
detecting at least one EOM (End Of Marker).
In the case of Failure(PSUE/PSUS):
• Issues Delete to make a deleting state for consistency group on each RCU
• Searches/commits a minimum matching point of the CTQ-Marker on RCU
via RCU (in other words, do Journal Restore with CTQ-Marker)
