Copying access attributes

If you create a BC pair using volumes that LUN Security XP Extension has set to VMA (Volume
Management Area), you can copy information about the access attribute in the P-VOL's VMA to the S-VOL.

P-VOL
Volume without VMA
Volume with VMA
NOTE: You can specify a volume with VMA as a reserve volume.
Figure 24 shows the process of copying of access attribute when you create a pair using volumes with
VMA.
NOTE: When you use volumes with VMA to create a BC pair, both the P-VOL and S-VOL must have VMA.
Figure 24

Copying access attribute

In Figure 24, if both the P-VOL and S-VOL have VMA, the P-VOL's VMA is copied to the S-VOL. In
Figure 24, the S-VOL's access attribute is Read/Write when the pair status is SMPL. After the P-VOL's VMA
is copied to the S-VOL, the S-VOL's access attribute is Read Only, which is same as the P-VOL's 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
46 Business Copy XP (BC) for the XP10000/XP12000
