NOTE:
If you need write access to an R-VOL, you must delete the pair.
Table 10
Suspend types
Suspend Type
Applies to
Description
M-VOL by
operator
M-VOL
(TC390 Sync only)
The user suspended the pair from the MCU using the M-VOL Failure
option. The R-VOL suspend type is by MCU.
R-VOL by
operator
M-VOL, R-VOL
The user suspended the pair from the MCU or RCU using the R-VOL
option.
by MCU
R-VOL
The RCU received a request from the MCU to suspend the volume pair.
The M-VOL suspend type is M-VOL by Operator or R-VOL by Operator.
by RCU
M-VOL
The MCU detected an error condition at the RCU that caused the MCU
to suspend the TC390 volume pair. The R-VOL suspend type is by MCU.
Delete Pair to
RCU
M-VOL
The MCU detected that the R-VOL status changed to simplex because the
user deleted the pair from the RCU. The pair cannot be resumed
because the R-VOL does not have the suspended status.
R-VOL Failure
M-VOL
The MCU detected an error during communication with the RCU or an
I/O error during update copy. In this case, the R-VOL suspend type is
usually by MCU.
MCU IMPL
M-VOL, R-VOL
The MCU could not find valid control information in its nonvolatile
memory during the IMPL procedure. This condition occurs only if the
MCU is completely without power for more than 48 hours (for example,
power failure and fully discharged backup batteries).
Initial Copy
failed
M-VOL, R-VOL
The volume pair was suspended before the initial copy operation was
complete. The data on the R-VOL is not identical to the data on the
M-VOL.
by FREEZE
M-VOL, R-VOL
(TC390 Sync only)
The volume pair was suspended by the CGROUP/RUN TSO command.
See ”
MCU P/S-OFF
R-VOL
(TC390A only)
The RCU received a request from the MCU to suspend the R-VOL due to
MCU power-off. The RCU stops expecting recordsets from that MCU.
by sidefile
overflow
M-VOL, R-VOL
(TC390A only)
The amount of sidefile exceeds the specified “current pending update
data rate” and the RCU data is not transferred within the specified
“offloading timer”.
