Figure 15 Shared Volume of Business Copy and Continuous Access Journal:

P-VOL/S-VOL

Caution:

When you use a Business Copy P-VOL as a Continuous Access Journal S-VOL as shown in

Figure 15

on page 35, the write operation to the Continuous Access Journal P-VOL may takes extra time

due to the time necessary for the copying process of the Business Copy pair.
In addition, note that if the journal volume size is small, the Continuous Access Journal pair may be

suspended by failure because of the shortage of the capacity of its journal volume.

Caution

: When you share a Business Copy P-VOL with a Continuous Access Journal S-VOL as shown

in

Figure 15

on page 35, Quick Restore or Reverse Copy can not be executed. The command will

be rejected if executed.
The configuration shown in

Figure 16

on page 36 is an example of a volume that is functioning as

both a Continuous Access Journal P-VOL and a Business Copy P-VOL, while the S-VOL of the same

Continuous Access Journal pair is also functioning as the P-VOL of another Business Copy pair. This

configuration allows:

On-site backup copies of Continuous Access Journal P-VOLs and S-VOLs

Remote backup of Business Copy P-VOLs
