Configurations with Continuous Access Journal volumes
You can use the ESAM S-VOL as a Continuous Access Journal (Cnt Ac-J) P-VOL. This configuration
benefits the ESAM pair if data in the P-VOL and S-VOL become inconsistent due to a disaster. In
this case, you can recover the data from the split Cnt Ac-J S-VOL.
Configuring ESAM with Continuous Access Journal
You perform this configuration by creating an ESAM pair and a Cnt Ac-J pair.
1. Create the ESAM pair. Make sure that the pair status becomes PAIR.
2. Create the Cnt Ac-J pair. Specify the ESAM S-VOL as a Cnt Ac-J P-VOL.
