TPC-R cooperation support
The Basic HyperSwap function of TPC-R (IBM disaster recovery software) has the following
requirements:
•
System option mode 114 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 24)
. If a path is not established, Basic
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.
