5 Performing XP Continuous Access configuration operations
XP Continuous Access configuration operations include MCU operations, RCU operations, XP
Continuous Access Asynchronous control operations, and discontinuing XP Continuous Access
operations. The XP Continuous Access main pane (
“XP Continuous Access main pane” (page 51) )
provides access to the following XP Continuous Access configuration operations:
•
“MCU operations” (page 67) , configure the MCUs for XP Continuous Access operations
◦ “Configuring MCU ports” (page 67)
•
RCU operations , configure RCUs for XP Continuous Access operations
Viewing RCU Status (RCU Status) ◦
◦ Registering RCUs (Add RCU)
◦ Modifying RCU options (Change RCU Option)
◦ Adding and deleting logical paths for RCUs (Add Path/Delete Path)
◦ Adding and deleting SSIDs for RCUs (Add SSID/Delete SSID)
◦ “Deleting RCUs (Delete RCU)” (page 76)
•
“XP Continuous Access Asynchronous operations” (page 81) , configure XP Continuous Access
Asynchronous groups and options
◦ “Modifying parameters and deleting settings” (page 81)
◦ “Adding consistency groups (Add CT Group)” (page 83)
◦ “Modifying consistency group options (CT Group Option)” (page 84)
◦ “Viewing consistency group status (CT Group Status)” (page 82)
◦ “Deleting consistency groups (Delete CT Group)” (page 86)
•
“Usage Monitor operations” (page 89) collect I/O statistics for LDEVs on a disk array
•
History operations display XP Continuous Access history file
•
“Optimizing XP Continuous Access operations and disk array performance” (page 92)
•
“Discontinuing XP Continuous Access operations” (page 94)
The XP Continuous Access main pane provides access to all XP Continuous Access volume pair
operations: creating pairs, splitting and resyncing pairs, and viewing pair status.
“Performing XP
Continuous Access pair operations” (page 94) provides instructions for performing the XP Continuous
Access volume pair operations.
MCU operations
MCUs are disk control units that control P-VOLs of XP Continuous Access volume pairs. MCUs
receive and process user-requested XP Continuous Access commands from the XP Command View
Advanced Edition management station or XP Remote Web Console, and send remote copy
operations to RCUs. MCUs can also function as RCUs if remote copy connections are properly
configured.
To set a disk array as an MCU, configure MCU ports.
Configuring MCU ports
All Fibre Channel interface ports on the disk array have a default setting of Target port (CHF).
Target mode is used for host processor channel interfaces. Fibre Channel ports used for XP
Continuous Access communications to RCUs must be configured as Initiator ports. Fibre Channel
interface ports in the RCU used to communicate with the MCU must be configured as RCU target
