Hitachi Universal Replicator for IBM /OS User’s Guide
Figure 8-2 Add Pair Window
The Add Pair window displays the following:
• P-VOL: Indicates a primary data volume. The numbers are the LDKC
number, the CU number and the LDEV number of the primary data volume.
Notes:
– P-VOL displays only one primary data volume even when two or more
primary data volumes are selected in the Pair Operation window. P-VOL
only displays the primary data volume that has the smallest volume
number.
– If a volume is an external volume, the symbol "#" appears after the
LDEV number. For detailed information about external volumes, please
refer to the Universal Volume Manager User's Guide.
• S-VOL: Allows you to select a secondary data volume. When specifying a
secondary data volume, you must use the two drop-down lists to select the
CU image number and the LDEV number of the secondary data volume.
Note: You can select only one secondary data volume even when two or
more primary data volumes are selected in the Pair Operation window. URz
automatically specifies the other secondary data volumes. For detailed
information, refer to the explanation about the Select Other S-VOL(s)
option later in this section.
