• 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.
