of a BC pair.

Combining BC and Continuous Access XP Journal operations
Continuous Access XP Journal volumes can be assigned to BC pairs, and BC volumes can be assigned
to Continuous Access XP Journal pairs.
BC and Continuous Access XP Journal can function together in the same disk array to provide both
internal and remote backup for your important data.
NOTE:
•
A primary volume (P-VOL) of Continuous Access XP Journal means a primary data volume of
Continuous Access XP Journal. A secondary volume (S-VOL) of Continuous Access XP Journal
means a secondary data volume of Continuous Access XP Journal.
• Combining BC L1 and L2 pairs with Continuous Access XP Journal volumes is allowed. Continuous
Access XP Journal considers node and leaf volumes as secondary volumes (S-VOLs).
The configuration shown in Figure 21 is an example of a volume that functions as both a Continuous
Access XP Journal P-VOL and a BC P-VOL. This configuration allows you to:
• Use BC to provide on-site backup copies of Continuous Access XP Journal P-VOLs
• Use Continuous Access XP Journal to provide remote backup copies of BC P-VOLs
