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 ”

CGROUP (FREEZE/RUN) support

” on page 173.

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”.
