68 External Storage XP panes
• Port Operation list
Displays detailed information about ports selected in the Port Operation tree. For more information,
see ”Port Operation list” on page 69.
• Information area
Displays the total number of ports currently displayed in the Port Operation list (Total Number of Ports).
• Preset List
Displays rows corresponding to the ports that are about to be acted upon. The contents displayed in
the Preset list have not been applied to the local array yet. When you click Apply on the Port
Operation pane, actions designated in the Preset list are applied to the local array. For more
information, see ”Preset list (Port Operation pane)” on page 70.
• Operation information area
Displays operation information about settings displayed in the Preset list.
• Operation: Setting operation name.
• Number of Objects in Preset: Number of settings displayed in the Preset list.
• Apply button
Applies actions designated in the Preset list to the local array. When actions are applied without
error, they are removed from the Preset list. If errors occur, actions are not applied, error messages
appear, and the actions remain in the Preset list.
• Cancel button
Cancels all settings in the Preset list.
Port Operation tree
Displays ports in the connected local array. Contents displayed in the Port Operation list (right pane)
varies according to the item selected in the Port Operation tree (left pane).
Figure 38 Port Operation tree
• Subsystem
When selected, displays nothing in the Port Operation list. Subsystem is selected when you initially
display the Port Operation pane.
• External
When selected, displays ports designated a external ports, which is the port attribute used for External
Storage XP. External ports do not have High Speed mode.
• Initiator
When selected, displays ports designated as an initiator (sending) port (used for Continuous Access
XP, TrueCopy for z/OS, Continuous Access XP Journal, Universal Replicator for z/OS, and so on).
• Target
When selected, displays ports designated as host target ports (used for host connect).
• RCU Target
When selected, displays ports designated as an RCU target (receiving) port (used for Continuous
Access XP, TrueCopy for z/OS, Continuous Access XP Journal, Universal Replicator for z/OS, and so
on).
• Initiator/External
When selected, displays ports for which the Initiator/External MIX mode is set.
• Port number
