Table 10 Consistency Status for Suspended TrueCopy for Mainframe Async P-Vols
Description
Consistency Status
This TrueCopy for Mainframe Asynchronous pair was
probably suspended alone. Update sequence consistency
between this R-VOL and other R-VOLs in this consistency
group is not ensured. This R-VOL cannot be used for disaster
recovery at the secondary system. This status is indicated
when:
•
This pair was suspended due to a failure that did not
affect the entire consistency group, and the Error Level
pair option for this pair is set to Volume.
•
This pair was suspended by a user-initiated suspend pair
operation with the TrueCopy for Mainframe Asynchronous
Suspend Range suspend option set to Volume.
Volume
This TrueCopy for Mainframe Asynchronous pair was
suspended along with the other pair in its consistency group.
Update sequence consistency between this R-VOL and other
R-VOLs in this consistency group is ensured. This R-VOL can
be used for disaster recovery at the secondary system (after
releasing the TrueCopy for Mainframe pair from the RCU).
This status is indicated when:
•
All pairs in this consistency group were suspended due
to a failure that affected the entire consistency group (not
just one pair) (for example, MCU-RCU communication
failure).
•
The pair was suspended due to a failure that did not
affect the entire group, and the Error Level TrueCopy for
Mainframe Asynchronous pair option for this pair is set
to Group.
•
This pair was suspended by a user-initiated suspend pair
operation with the TrueCopy for Mainframe Asynchronous
Suspend Range suspend option set to Group.

Suspended TrueCopy for Mainframe Async Pairs
TrueCopy for Mainframe Async operations involve additional suspension conditions related to the
asynchronous recordset operations. Both the MCU and RCU can detect TrueCopy for Mainframe
Asynchronous suspension conditions and suspend TrueCopy for Mainframe Asynchronous pairs.
“TrueCopy for Mainframe Async Suspension Conditions” (page 38)
describes the TrueCopy for
Mainframe Asynchronous suspension conditions and indicates which CU detects the condition and
which pairs are suspended. The TrueCopy for Mainframe Asynchronous offloading timer async
option and timeout group options are used to control the TrueCopy for Mainframe Asynchronous
suspension conditions. See
“Resolving TrueCopy for Mainframe Async Suspension Conditions”
for troubleshooting information for TrueCopy for Mainframe Asynchronous suspension
conditions.

Suspension Condition
All TrueCopy for Mainframe
Asynchronous pairs with M-VOLs in the
MCU.

The MCU could not send a pending
recordset to the RCU before the
offloading timer async option expired.

MCU.
MCU
During MCU power-on, the MCU
could not establish communication
with the RCU before the RCU Ready
timeout group option expired.
