“Resolving XP Continuous Access Journal Pair Suspension” (page 220) provides troubleshooting
instructions for XP Continuous Access Journal pair suspension. Hardware failures that affect the
cache memory and the shared memory of the primary or secondary storage system may also cause
the XP Continuous Access Journal pairs to be suspended.
