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

XP LUN Security Extension license capacity
To create an XP Continuous Access Journal pair using volumes with VMA, if the primary data
volume has an access attribute for which the XP LUN Security Extension license is necessary, you
need the XP LUN Security Extension license capacity for secondary data volumes in the 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 40 (page 86) .
NOTE: If the XP LUN Security Extension license capacity is insufficient in the array at the secondary
site, you might not able to create XP Continuous Access Journal pairs. For more information, see
the HP StorageWorks LUN Security XP Extension user guide.
