56 Continuous Access XP Journal operations requirements and restrictions
Journal transfer speed of DKCs
A DKC’s journal transfer speed depends on the number of paths used for transferring journals. The
number of paths for transferring journals must be large enough that the journal transfer speed exceeds the
data transfer speed in the “normal status” mentioned previously. The maximum number of paths for each
pair of the primary and secondary DKC is 8.
NOTE: If the journal transfer speed falls short of the desired speed, check the channel processors’ usage
rate. If the usage rate of some channel processors is high, the journal transfer speed might increase if you
add channel processors.
Configuring primary and secondary arrays for Continuous Access XP
Journal operations
After installing the Continuous Access XP Journal hardware and software, you can configure the primary
and secondary arrays for Continuous Access XP Journal operations.
1. Identify the Continuous Access XP Journal data and journal volumes in the primary and secondary
arrays. You must know the array’s S/N and port ID, so you can configure the primary and secondary
arrays correctly for the desired pairs. When creating pairs, you must know each volume’s port, target
ID, and LUN.
2. Connect to the local array you want to use. For more information about Command View XP or XP
Remote Web Console installation and operations, 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 or contact your HP account support representative.
NOTE: You must log in with Administrator or Continuous Access XP Journal write access, and you
must be in Modify mode. If you are in the View mode, you can view the Continuous Access XP
Journal pair status, but you cannot modify the settings.
3. Click the Continuous Access XP Journal button ( ). The Journal Operation pane appears.
4. On the DKC Operation pane, select Port, and set the initiator and RCU target ports (see ” Configuring
port attributes ” on page 85).
5. On the DKC Operation pane, select DKC. The Add DKC pane appears.
6. Set the S/N of the array to be connected, controller ID, path group ID, initiator port in the array, and
RCU target port in the array to be connected (see ” Associating primary and remote arrays and
configuring logical paths (Add DKC) ” on page 86).
7. On the Add DKC pane, click Option, and set the local array’s options (see ” Associating primary and
remote arrays and configuring logical paths (Add DKC) ” on page 86).
8. On the Journal Operation pane, specify the journal group number.
9. On the Edit JNL Volumes pane, register the journal volumes (see ” Deleting journal volumes from
journal groups ” on page 102).
10. On the Paircreate pane of the Pair Operation pane, register the primary and secondary data volumes
and journal groups that are paired (see ” Creating a pair of data volumes (Paircreate) ” on page 122).
NOTE: Only the primary array can register Continuous Access XP Journal pairs.
11. Exit the Continuous Access XP Journal, and disconnect from the array.
12. Repeat step 3 through step 11 for each array that will function as a Continuous Access XP Journal
primary array. After configuring the primary arrays, adding the secondary arrays, and configuring the
Continuous Access XP Journal options and journal groups, you are ready to begin Continuous Access
XP Journal volume pair operations.
