•
MCU-RCU Path: Selected port type for remote copy connections. You cannot change the port type on
the CT Group Option pane.
•
Time Out (Copy Pending) (min.): Maximum delay (copy pending timeout) allowed for Continuous
Access XP Async copy (none or from 1 to 15 minutes; none = no timeout for Continuous Access XP
Async copy pending). The default is five minutes. If the delay between the Continuous Access XP
Async P-VOL update and corresponding S-VOL update reaches the specified time, the RCU suspends
all S-VOLs in the group. A timeout occurs when the RCU cannot settle a recordset within the specified
time or has not had any communications from one of the MCUs in the group within the specified time.
NOTE:
The copy pending timeout value should be less than the I/O timeout value of the host
system.
•
Time Out (RCU Ready) (min.): Maximum delay allowed for re-establishing MCU-RCU communications
following MCU power-off (none or from 1 to 10 minutes; none = no timeout for Continuous Access XP
Async RCU ready). The default is five minutes. If the MCU cannot re-establish communications with the
RCU within the specified time, the MCU suspends all P-VOLs in the group.
