Metrocluster with Continuous Access XP Version A.11.00 Release Notes, August 2010 (B8109-90027)

XP12000/10000/24000/20000 to XP12000/10000/24000/20000 with a 1-to-1 relationship.
That is, 1 journal group in one XP12000/10000/24000/20000 array can only pair with 1
journal group in another XP12000/10000/24000/20000 array.
Continuous Access Journal does not support operations in which one primary data
volume is copied to more than one secondary data volume, or more than one primary
data volume is copied to one secondary data volume.
Mode 449 for Continuous Access Journal Operations
Metrocluster supports Mode 449, which is set to the same value for XP10000, XP12000,
XP20000, and XP24000 disk arrays. The value of either “ON” or “OFF” should set for
XP10000, XP12000, XP20000, and XP24000 disk arrays. Metrocluster with Continuous
Access XP does not support a mixed setting of Mode 449. For example, if Mode 499=ON
for the primary array and Mode 449=OFF for the secondary array, this configuration
would not be supported. Contact your HP representative to verify and update the
Mode 449 settings.

Metrocluster with Continuous Access XP can be installed while the system is running
