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.
“Possible Combination of Version 1 and ShadowImage for Mainframe Pairs” (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. “Volume Combinations for Version 1 and
ShadowImage for Mainframe” (page 10) lists the combination of the volumes when you establish
a Version 1 relationship with ShadowImage for Mainframe pair volumes.
