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.

Table 20

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.

Table 20

shows the availability of LUN Security XP Extension

operations according to the pair status.

License capacity of LUN Security XP Extension

To create BC pairs using volumes with VMA, you need the license capacity of LUN Security XP Extension

for both P-VOLs and S-VOLs. This is because the S-VOLs have the same access as the P-VOLs when the

access attribute copy is complete. For more information about copying access attributes, see

Figure 24
