HP XP Continuous Access Software - Manual (Page 151)

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).
• If a logical volume is an external LU, # 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
automatically 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
are available. If an S-VOL is not available, you must select S-VOLs individually.
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, and click Set. Next, you must specify the secondary
data volume for the second primary data volume with S-VOL, and click Set.
• 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.
