12 Overview of LUN Security XP Extension
• Products that can start automatically at a specified time: Certain products, such as Auto LUN
Monitoring, start automatically at specified times. If a product that can start automatically is enabled,
you must perform LUN Security XP Extension operations when the program is not running or cancel the
program’s start time setting.
• Local array copy software users:
NOTE: The following information applies only if you want to set Volume Management Area
(VMA). You can set VMA only to logical volumes with an OPEN-V emulation type. For more
information, see ” Setting VMA ” on page 27.
• When creating a Business Copy XP, Continuous Access XP, or Continuous Access XP Journal pair,
you can only use volumes without VMAs for both the P-VOL and S-VOL, or use volumes with VMAs
for both the P-VOL and S-VOL.
• For a Business Copy XP, Continuous Access XP, or Continuous Access XP Journal pair, if the P-VOL
and S-VOL contain a VMA, you can copy the access attribute and S-VOL Disable setting in the
VMA from the P-VOL to the S-VOL. The copied access attribute and S-VOL Disable setting do not
take effect on the S-VOL when the pair status is PAIR. To make the copied access attribute effective,
change the Business Copy XP pair status to PSUS, or change the Continuous Access XP or
Continuous Access XP Journal pair status to PSUS or SMPL. To make the copied S-VOL Disable
setting effective, change the Business Copy XP pair status to PSUS, or change the Continuous
Access XP or Continuous Access XP Journal pair status to SMPL. For more information about
changing pair statuses and copying access attributes, see the HP StorageWorks Business Copy XP
user guide, HP StorageWorks Continuous Access XP user guide, or HP StorageWorks Continuous
Access XP Journal user guide for the specific array.
• Be careful about the license capacity when using volumes with VMAs or extents. For more
information about required license capacity for local array copy software when using volumes with
VMAs or extents, see ” Cautions about license capacity ”.
CAUTION: If you change a Business Copy XP pair status to PSUS and the S-VOL Disable setting
takes effect on the S-VOL, the pair cannot be resynchronized.
Cautions about license capacity
When using volumes with VMAs or extents for local array copy software, ensure that there is enough
license capacity. Otherwise, you might not be able to perform copy operations.
This section describes how to calculate the required license capacity for local array copy software when
using volumes with VMAs or volumes with VMAs and extents.
Calculating license capacity when VMA is set
To set access attributes on logical volumes with VMA that are specified as logical volumes of the pair of the
local array copy software, you need enough license capacity for the logical volume you are changing and
for other logical volumes forming the pair. In Figure 2 , LUN Security XP Extension changes logical volume
A’s access attribute, which has a capacity of 2 GB. In this case, because logical volume A forms a pair
