access attribute. When the pair status is PAIR, copied access attribute information is not effective, so
the S-VOL's access attribute is still Read/Write. To make the copied access attribute information
effective, split the pair and make the pair status PSUS. When the pair status is PSUS, the S-VOL's
access attribute changes to Read Only. For more information about pair status and operations related
to the access attribute, see
CAUTION:
Because the S-VOL's access attribute is changed after copying the P-VOL's access attribute, be careful
about access attributes of volumes to be specified as BC pairs. For example, if the P-VOL's access
attribute is S-VOL Disable, the S-VOL's access attribute is also S-VOL Disable after copying the access
attribute. You cannot perform Pairresync operations on the S-VOL that has the S-VOL Disable access
attribute. You must change the access attribute to something other than S-VOL Disable. For more
information about changing the access attribute, see the
HP StorageWorks LUN Security XP Extension
user guide.
You can set VMA, which is required to copy the access attribute, only when the volume's emulation
type is OPEN-V.
shows whether you can create pairs according to the VMA setting.
Whether you can use LUN Security XP Extension to change or reference the access attribute for BC
pair volumes depends on the pair status.
