If the following operation or processing is executed, the FCWITHDR command may be issued
automatically by a host server and relationships may be deleted:
•
A user deletes a dataset.
•
A user initializes a volume.
•
A temporary dataset is deleted when a job completes.

External Volume
XP External Storage
•
External volumes are the volumes in the external storage system that are mapped as the internal
volumes. For details about XP External Storage and external volumes, see the HP
XP24000/XP20000 External Storage Software User Guide.
•
If an external volume is specified as a Version 2 T-VOL, be careful about the setting for the
time of path blockade watch, which is the time from when the external storage system is
disconnected to the path blockade watch. If the time of path blockade watch that is set for
the T-VOL is longer than the time of the Missing Interrupt Handler (MIH) timer that is set for
the S-VOL on the host side, an MIH may occur on the S-VOL and the processing may end
abnormally when the external storage system is powered off or when failures occur.
•
If the host I/O to the S-VOL is more important than the host I/O to the T-VOL, make sure that
the time of the path blockade watch that is set for the T-VOL is smaller than the time of the
MIH timer set for the S-VOL. This way, the Version 2 relationship will be suspended when the
