respective disk arrays.
Common procedure for Continuous Access XP pair operations
Use the Continuous Access XP main pane to perform pair setting operations. All operations performed
from the Continuous Access XP main pane have the following common procedure:
1. Click a CU number in the CU Number/Port Number tree.
NOTE: You must select a CU number in the tree. If you select a Port number, pair setting operations
cannot be performed.
2. Click one or more LUs or pairs in the Volume list.
3. Right-click. The pop-up menu consists of:
• Pairdisplay: Displays LU status (see ”Viewing Continuous Access XP pair status for LUs and LDEVs
(Pairdisplay)” on page 89).
• Paircreate: Creates a volume pair using the Synchronous and Asynchronous commands (see
”Creating Continuous Access XP volume pairs (Paircreate)” on page 90).
• Pairsplit-S: Deletes pairs (see ”Deleting Continuous Access XP volume pairs (Pairsplit-S)” on
page 99).
• Pairsplit-r: Splits (Suspends) pairs (see ”Splitting Continuous Access XP pairs (Pairsplit-r)” on
page 94).
• Pairresync: Resumes pairs (see ”Resuming Continuous Access XP volume pairs (Pairresync)” on
page 97).
• Change Pair Option: Changes pair options (see ”Changing pair options (Change Pair Option)” on
page 102).
4. Click a command, and use the pane to make your settings.
5. Click Set to set parameters. The Cancel button closes the pane, but does not set the settings. The Cancel
All button returns to the Volume list.
NOTE: After being set, options can be modified and canceled (see ”Modifying parameters and
deleting LUs” on page 88).
6. Click Apply on the Continuous Access XP main pane to apply the settings to the disk array.
Active commands in the pop-up menu displayed in step 3 are in black letters. Inactive commands are in
gray letters. Whether commands are active or inactive depends on the status of LUs selected in the Volume
list.
The following sections describe each command and operation in detail.
List after command selection
After the pane closes, only LUs selected in step 2 of the procedure described in the ”Common procedure
for Continuous Access XP pair operations” on page 88 are displayed in the list. Items of the list also
change. The Volume list in this status is called the Pair Settings Parameter list. Items of the Pair Settings
Parameter list depend on the command clicked from the pop-up menu and the operation performed. Items
for each command are described in the following sections.
The Set button on each parameter pane presets parameters to the Pair Settings Parameter list. To apply
parameters to the system, click Apply on the Continuous Access XP main pane.
The Cancel button closes the pane, but does not set parameters. The Cancel All button returns to the Volume
list.
Modifying parameters and deleting LUs
After pair settings operations, LU parameters can be modified individually. LUs selected to be the pairs can
be deleted.
