STATUS
: Places P-VOL in fence
status (updates suppressed) when
updates in P-VOL cannot be

problem such as a failure. If the
operation from the primary site
attains the suspend status,
updates to P-VOL are accepted.

When a copy pair is suspended,
updates to P-VOL are accepted.

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.
