license capacity for both logical volumes A and B. Therefore, LUN Security XP Extension needs

4 GB of license capacity.

Figure 2 Calculating license capacity

NOTE: If you do not change the logical volumes’ default access attribute, which is Read/Write,

you do not need extra license capacity. For example, in Figure 2, if you set VMA on logical volumes

A and B when they do not form a pair, 2 GB of license capacity is enough. However, in Figure 2,

VMA is set on logical volume A and logical volume A’s access attribute is changed to Read Only.

Since logical volumes A and B form a pair, in Figure 2, you need 4 GB of license capacity.

When you set VMA and the access attribute to a logical volume that is not specified as the logical

volume of a pair, and then create a pair using that logical volume, you need enough license

capacity for both logical volumes forming the pair. Therefore, if LUN Security XP Extension’s license

capacity is insufficient, you cannot create a pair even if the license capacity of local disk array copy

software is sufficient. Figure 3 shows an example of this case.

Figure 3 Example of when you cannot create a pair

Starting LUN Security XP Extension

To use LUN Security XP Extension, install the following:

• LUN Security XP Extension license key.

• Firmware version 21.07.04 or later. To use the Expiration Lock feature, firmware version 21.10.02 or

later is required.

To assign an access attribute, you must use an account that has write permission, such the Administrator

account, and you must be in Modify mode. If you use an account that does not have write permission or

you are in View mode, you can view the volume’s access attribute, but you cannot assign an access

attribute.

1. Launch Command View XP or XP Remote Web Console.
