74 Continuous Access XP Journal
NOTE: If the pair is suspended or deleted during COPY status, the primary data volume’s access attribute
is not copied to the secondary data volume. To copy the primary data volume’s access attribute to the
secondary data volume, ensure that the pair status is PAIR, and then suspend or delete the pair.
NOTE: When the primary data volume is in COPY or PAIR status, two access attributes can be changed
and cannot be changed according to the existing access attribute. For more information about the variable
access attribute, see Table 24.
LUN Security XP Extension license capacity
To create a Continuous Access XP Journal pair using volumes with VMA, if the primary data volume has an
access attribute for which the LUN Security XP Extension license is necessary, you need the LUN Security
XP Extension license capacity for secondary data volumes in the disk array at the secondary site. This is
because when copying the access attributes is complete, primary and secondary data volumes have the
same access attributes. For more information about copying access attribute, see Figure 36.
NOTE: If the LUN Security XP Extension license capacity is insufficient in the disk array at the secondary
site, you might not able to create Continuous Access XP Journal pairs. For more information, see the
HP StorageWorks LUN Security XP Extension User Guide.
