Changing options for logical paths and arrays
Use the DKC Option pane to set logical path and array options. These options apply to the local array.
NOTE: DKC is an acronym for disk controller, which controls an entire array. Continuous Access XP
Journal panes use the word DKC to indicate an array.
To change logical path and array options, the primary and secondary array administrators can perform
the following procedure:
1. Ensure that Command View XP or XP Remote Web Console is in Modify mode. For more information,
see the HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks
XP Remote Web Console user guide for XP12000/XP10000/SVS200.
2. Display the DKC Operation pane (” Displaying the DKC Operation pane ” on page 81).
3. In the Switch Display box, select DKC.
4. Select Subsystem from the tree. A list of remote arrays appears.
5. From the list, right-click the remote array.
6. Select DKC Operations and Change DKC Option. The DKC Option pane appears.
7. On the DKC Option pane, change the options as needed.
8. Click Set to close the DKC Option pane.
9. In the Preset list, check the settings you made.
• To modify a setting, right-click the setting from the Preset list, and select Modify. A pane appears
where you can modify the setting.
• To cancel a setting, right-click the setting in the Preset list, and select Cancel.
10. Click Apply to apply the settings.
NOTE: If an error occurs, the right-most column of the Preset list displays the error code. To view
detailed information about the error, right-click the error code, and select Error Detail. An error
message appears providing detailed information about the error.

• Minimum Paths: Minimum number of paths required for each remote array connected to the local
array (default is 1).
An error occurs if you enter a larger number than the number of paths already set on the Add DKC
pane, or if the number of paths falls below this number (for example, due to path failures). When an
error occurs, the local array suspends all affected Continuous Access XP Journal (and Universal
Replicator for z/OS) pairs to prevent remote copy operations from adversely affecting performance
due to an inadequate number of paths.
If the local array contains Continuous Access XP Journal pairs that contain critical data for disaster
recovery, set the minimum number of paths to one, so Continuous Access XP Journal operations
continue even if there is only one path to a remote array.
