Creating a pair of data volumes (Paircreate)
Using the Paircreate pane, the administrator of the primary array must create pairs of primary and
secondary data volumes. When creating a pair, the administrator can specify options for initial copy
activities.
Before creating one or more pairs, the administrator must ensure that:
•
Volumes to be used as secondary data volumes are offline to all hosts.
•
Ports have already been configured (see ”
•
The primary array is associated with the secondary array (see ”
Associating primary and remote
arrays and configuring logical paths (Add DKC)
After all these points are confirmed, the administrator of the primary array can use the following
procedure to create a pair of a primary and secondary data volume. The administrator of the secondary
array cannot perform this operation.
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 Pair Operation pane.
3.
In the tree, select a port ( ), host group (
), or iSCSI target (
).
4.
In the list, select and right-click the volume you want to use as a primary data volume.
NOTE:
• Volumes with the
icon are already used as primary data volumes.
• You can select and right-click more than one volume to create more than one pair at one time.
You must choose all secondary data volumes from the same secondary array.
• When selecting more than one volume, select volumes belonging to the same CLPR. To select
volumes when the Preset list already contains a volume, select the CLPR where the volume
belongs, and select volumes belonging to that CLPR.
5.
Select Paircreate. The Paircreate pane (
) appears.
6.
In the DKC box, specify the secondary array.
7.
In the S-VOL box, specify the secondary data volume.
• Use the left-most list to specify a port.
• Use the list in the middle to specify a G-ID, which is the group number of a host group or iSCSI
target.
• Use the right-most list to specify a LUN.
NOTE:
If more than one primary data volume is specified in the list, you can specify secondary
data volumes in three ways. For more information, see the explanation for the Select Other
S-VOL(s) option on page 124.
8.
Use the Mirror lists to specify the following items sequentially:
• Master journal group
• Mirror ID
• Restore journal group
9.
In the CTG box, specify a consistency group number.
10.
Do one of the following to make settings on the initial copy operation:
• To start the initial copy operation immediately after the pair is created, select Entire.
• To not start the initial copy operation immediately after the pair is created, select None.
11.
Use Error Level to specify the range used for splitting a pair when a failure occurs.
