Example of FCWITHDR Command Description (for Case 7)
Since no relationship is withdrawn by performing the abovementioned command, there will be no change
in the number of relationships after using the command.
Note that even if you do not issue this command, the write operation to volumes may be resumed
automatically if the state-change-pending delay time elapses. For information about the
state-change-pending delay time, see ”
CAUTION:
When the relationships are withdrawn by the FCWITHDR command executed with DDSW
parameter set to NO or without setting the DDSW parameter, the data integrity of the T-VOL cannot be
guaranteed.
CAUTION:
If you use the FCWITHDR command only one time when deleting numerous relationships, a
timeout might occur with the host. Use the FCWITHDR command more than one time when deleting
numerous relationships. Also, after you execute the FCWITHDR command one time, wait for a while before
executing the FCWITHDR command again. For example, if you execute the FCWITHDR command one
time when deleting 700 relationships, wait for approximately 5 seconds before executing the command a
second time.
