• Monitoring Time (min)
Specify the monitoring time, before transition to the "HALT " status for a copy session
when a REC Buffer shortage occurs. If the REC Buffer is in a high-load state for the
specified monitoring time, the copy session is automatically changed to "HALT" state.
When "0" is specified in this field, REC Buffer shortage monitoring is not performed.
If "Unused" is selected for the usage, a "-" (hyphen) is displayed.

• HALT Wait Timer (sec)
Specify the maximum non-response time. During the non-response time, the host I/O
response is stopped to give priority to performing REC Buffer transfers in a high-load
state. If the non-response time exceeds the specified value, response to host I/O is
restarted. However, the copy session is changed to the "HALT" state. When "0" is
specified for this field, ETERNUS DX Disk storage system gives priority to the host I/O,
and the copy session is immediately changed to "HALT" state.
If "Unused" is selected for the usage, a "-" (hyphen) is displayed.
