NOTE:

• P-VOL displays only one primary data volume even when two or more primary data volumes

are selected in the Pair Operation pane. P-VOL only displays the primary data volume that

has the smallest LUN (LU number).

• IfalogicalvolumeisanexternalLU,# appears after the LDEV number. For more information

about external LUs, see the

HP StorageWorks External Storage XP

user guide.

• S-VOL: Select a secondary data volume. When specifying a secondary data volume, use the lists

to select the secondary data volume's port, G-ID, and LUN. The G-ID is the group number for a

host group or iSCSI target.

NOTE:

You can select only one secondary data volume even when two or more primary data volumes are

selected in the Pair Operation pane. Continuous Access XP Journal automatically speciﬁes the

other secondary data volumes. For more information, see the explanation for the Select Other

S-VOL(s) option.

NOTE:

If you selected more than one primary data volume, select the secondary data volume for the primary

data volume

being displayed. Secondary data volumes for the remaining primary data volumes are

automatica

lly assigned according to the LUN. For example, if you select three primary data volumes

and select

LUN01 as the S-VOL for the ﬁrst primary data volume, the secondary data volumes for the

two other primary data volumes are LUN02 and LUN03.

NOTE:

When creating more than one pair at a time, ensure that the S-VOLs to be automatically assigned

areavailable.IfanS-VOLisnotavailable,youmustselectS-VOLsindividually.

NOTE:

You can specify the port number with two characters. For example, you can abbreviate CL1-A to 1A.

You can also enter the port number in both lowercase and uppercase characters.

• Select Other S-VOL(s):Speciﬁes how Continuous Access XP Journal automatically assigns

secondary data volumes if you select two or more primary data volumes in the Pair Operation

pane.

• Increment: Continuous Access XP Journal increments the resulting secondary data volumes'

LUNs by one. For example, if the three primary data volumes' LUNs are 001, 002, and 003,

the resulting secondary data volumes's LUNs are 011, 012, and 013 if you select LUN 011

from the S-VOL list.

• Input Next: You can specify a LUN for each primary data volume. For example, if you select

two primary data volumes, you must select Input Next, specify the secondary data volume for

the ﬁrst primary data volume with S-VOL,andclickSet. Next, you must specify the secondary

data volume for the second primary data volume with S-VOL,andclickSet.

• Relative to P-VOL: Continuous Access XP Journal calculates the difference between LUNs

of two adjacent primary data volumes, and then determines the secondary data volumes'

LUNs. For example, if the three primary data volumes' LUNs are 001, 005, and 006, the

resulting secondary data volumes' LUNs are 002, 006, and 007 if you select LUN 002 from

the S-VOL list.
