Description
Specify the journal group number
of the secondary site as a sub C/T
group ID (required)
Specify a value between OO and
FF.
NOTE: For configurations that use
delta resync, specify the same value
for both the UR copy pair and the
UR copy pair for delta resync.
Specify the Mirror ID in the range
from 0 to 3 (required for CAJ).
Specify the fence level (required for
CA).
DATA: Places P-VOL in fence
status (updates suppressed) when
updates in P-VOL cannot be
copied to S-VOL due to a
problem such as a failure.
STATUS: Places P-VOL in fence
status (updates suppressed) when
updates in P-VOL cannot be
copied to S-VOL due to a
problem such as a failure. If the
operation from the primary site
attains the suspend status,
updates to P-VOL are accepted.
NEVER: P-VOL is never in fence
status (updates suppressed).
When a copy pair is suspended,
updates to P-VOL are accepted.
NOTE:
FENCE LVL cannot be altered
when a C/T group ID is
specified.
For the system volume that is
used for control by the OS or
applications such as Business
Continuity Manager, specify
DATA or STATUS for FENCE LVL
to create a copy pair and
operate the system. Write to
P-VOL is prohibited and the OS
or application might hang when
a failure problem occurs. For that
reason, if you use the system
volume as a CA copy pair,
specify NEVER for FENCE LVL or
set the system volume itself not
to CA copy the pair.
Specify whether to freeze a storage
system (place in SCP status) when
a failure suspension (SUSPER)
occurs.
