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.
