Combining Continuous Access XP and LUN Security XP Extension

You can use Continuous Access XP to create a pair using the volumes that you used LUN Security XP
Extension to set the access attribute. However, you cannot create a Continuous Access XP pair by
specifying a volume that has the S-VOL Disable attribute as an S-VOL.
Table 14 shows whether you can specify a volume with access attribute as a P-VOL or S-VOL of a
Continuous Access XP pair.

Copying access attributes

If you use LUN Security XP Extension to create a Continuous Access XP pair using the volumes to which the
VMA is set, you can copy the P-VOL's access attribute recorded in the VMA to the S-VOL. You can set the
VMA required to copy the access attribute only to OPEN-V volumes.
For more information about LUN Security XP Extension, see the HP StorageWorks LUN Security XP
Extension user guide.
