The Asynchronous Operation window presents:
• Operation: indicates the current operation performed on the
Asynchronous Operation window.
• Tree: allows you to display all consistency groups (except groups used for
TrueCopy) belonging to LDKC#00 (default), or all consistency groups
(except groups used for TrueCopy) belonging to LDKC#01. For each LDKC,
this tree displays the consistency groups that are already in use (Used), and
the consistency groups that are available for use (Not Used).
Note: LDKC#01 is not available for the current microcode version.
• List: displays the following consistency group information:
– CTG: Consistency group number.
– This CU: the CU to which the group is registered. MCU: The group was
added from the connected CU. RCU: The group was added from the
paired CU (connected CU is RCU). M&R: MCU and RCU are in the same
storage system.
– M-R Path: Channel type: fibre. If the consistency group is not in use,
this column is blank.
– Offloading Timer: the time until the TrueCopy for z/OS Async recordset
is transferred. If the consistency group is not in use, this column is blank.
If this CU is RCU, this parameter is invalid, and a hyphen is displayed in
this column.
– Inflow Control: indicates whether the inflow control is enabled or not. If
the consistency group is not in use, this column is blank. If this CU is RCU,
this parameter is invalid, and a hyphen is displayed in this column.
– Paired S/N: Serial number of the paired storage system (if there is
more than one RCU, the storage system with the lowest S/N is displayed).
LDKC number is also displayed next to the S/N. If the consistency group is
not in use, this column is blank.
– Paired SSID: SSID of the paired storage system (if there is more than
one RCU, the storage system with the lowest SSID is displayed). If the
consistency group is not in use, this column is blank.
– Other S/N: Exist: indicates that there is more than one RCU for the
group. If there is only one RCU, this column is blank.
– CLPR: the number and name of the CLPR which the volumes forming
pairs belong to. If the consistency group is not in use, this column is
blank. For further information on CLPR, please refer to the Virtual Partition
Manager User's Guide.
