TPC-R cooperation support
The Basic HyperSwap function of TPC-R (IBM disaster recovery software) has the following
requirements:
System option mode 1 14 is set to OFF.
System option modes 484 and 769 are set to ON.
Cnt Ac-S Z synchronous pairs are created after both the paths from MCU to RCU and from
RCU to MCU are established.
When performing a Basic HyperSwap to exchange M-VOLs and R-VOLs, Cnt Ac-S Z synchronous
pairs are resynchronized using the path that is already established (see
Z synchronous pair M-VOLs and R-VOLs using TPC-R" (page
HyperSwap will not complete correctly.
For optimal performance, the maximum number of pairs for Basic HyperSwap is 1,000 per CHA,
which is the path for accessing connected Cnt Ac-S Z volumes.
If Basic HyperSwap is performed from TPC-R, the MIH value of the host I/O and host operation
needs to be approximately one second.
If the Basic HyperSwap function is performed from TPC-R, the resources in the host system must be
ensured sufficiently. If the shortage of resources occurs, resynchronization for Cnt Ac-S Z synchronous
pair may fail with the messages of IOSHM0803E (HyperSwap Disabled) and IOSHM0201I (Reason
Code:40) in the host system. If the resynchronization failed, restore the resource shortage, and
then delete the failed M-VOL and R-VOL Cnt Ac-S Z pair in suspend status from the TPC-R. The pair
create operation must be initiated again after the failed pair deletion.
