You can share
SIz P-VOLs and S-VOLs with
URz P-VOLs and S-VOLs that are in 3DC
configurations with three
URz sites.
The following
figures show examples of sharing SIz and URz volumes in the
following configurations:
- 3DC multi-target configuration
- 3DC multi-target configuration using delta
resync
- 3DC cascade configuration
- 3DC cascade configuration using delta resync
(1) When a URz P-VOL is shared with an SIz P-VOL in a 3DC multi-target configuration
(2) When a URz P-VOL is shared with an SIz S-VOL in a 3DC multi-target configuration
(3) When a URz S-VOL is shared with an SIz P-VOL in a 3DC multi-target configuration
(4) When a URz P-VOL is shared with an SIz P-VOL on the primary storage system in a 3DC cascade configuration
(5) When a URz P-VOL is shared with an SIz S-VOL on the primary storage system in a 3DC cascade configuration
(6) When a URz S-VOL is shared with an SIz P-VOL on the intermediate storage system in a 3DC cascade configuration
(7) When a URz S-VOL is shared with an SIz P-VOL on the secondary storage system in a 3DC cascade configuration
(8) When each URz volume is shared with an SIz P-VOL in a 3DC multi-target configuration using delta resync
(9) When a URz P-VOL is shared with an SIz S-VOL, and a URz S-VOL is shared with an SIz P-VOL in a 3DC multi-target configuration using delta resync
(10) When each URz volume is shared with an SIz P-VOL in a 3DC cascade configuration using delta resync
(11) When a URz P-VOL is shared with an SIz S-VOL, and a URz S-VOL is shared with an SIz P-VOL in a 3DC cascade configuration using delta resync
