Figure 2 Possible Combination of Version 1 and ShadowImage for Mainframe Pairs
• You cannot add a Version 1 L2 relationship onto a Version 1 L1 relationship.
• You cannot add a third layer (L3 pair) onto a Version 1 L2 relationship or a ShadowImage
for Mainframe L2 pair.
• If the L2 pair is in F-Copy status, you can only suspend or delete the ShadowImage for
Mainframe L1 pair.
(page 10) shows the configuration in which you share ShadowImage for Mainframe T-VOLs and
S-VOLs for the Version 1 relationships. In addition to this configuration, you may specify a
ShadowImage for Mainframe S-VOL as an S-VOL of a Version 1 relationship. (page 10) lists the
combination of the volumes when you establish a Version 1 relationship with ShadowImage for
Mainframe pair volumes.
