When the S-VOL’s mode is “noread”, you can refer to the access attribute only when the pair status is COPY(SP), PSUS, or
PSUS(SP). For more information about the “noread” mode, see the HP StorageWorks RAID Manager XP user guide.
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 25.
You can also copy access attributes of cascaded pairs. Figure 26 shows the required license capacity
of LUN Security XP Extension when you create cascaded pairs using volumes with VMAs and access
attributes.
Figure 26 Required license capacity for LUN Security XP Extension when using cascade function
.
In Figure 26, VMAs are set to cascaded pairs' volumes. Before copying, the root volume's access
attribute is Read Only, the node and leaf's access attribute is Read/Write. When copy operations,
such as update copy or pairresync, are performed on these cascaded pairs, the root volume's access
attribute is copied to the node and leaf volumes. Therefore, to set the access attribute for volumes
used in cascade pairs, LUN Security XP Extension needs license capacity for the root volume and the
