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 XP
Continuous Access Async copy (none or from 1 to 15 minutes; none = no timeout for XP
Continuous Access Async copy pending). The default is five minutes. If the delay between the
XP Continuous Access 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 XP Continuous Access 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.
