Viewing a connectivity report for a CTC connection

Select the connection from the CTC Connections and press Details..., the View CTC Connection Details dialog will appear, showing all image-to-image connections showing the control units and devices that each image uses to access the other image.

It is possible for each image-to-image connection to span multiple listbox entries. As an example, if all of the images used in the example above used 4 CTC devices and 4 BCTC devices, there would be 12 listbox entries, the first 4 showing:

LPAR11    4110     4110,4       00      5110,4       5110      LPAR12
LPAR11    4110     4114,4 (B)   04      5114,4 (B)   5110      LPAR12
LPAR12    4120     4120,4       00      5120,4       5120      LPAR11
LPAR12    4120     4124,4 (B)   04      5124,4 (B)   5120      LPAR11

Furthermore, this listbox will have entries to show devices that use unit addresses not mirrored on the destination image. These entries will show blanks in control unit and device columns on either the left or right side. To illustrate, assume LPAR12 is excluded from device 5112’s explicit candidate list. The first listbox item would be split into three entries as follows:

LPAR11     4110     4110,2       00      5110,2       5110    LPAR12 
LPAR11     4110     4112,1       02                           LPAR12 
LPAR11     4110     4113,1       03      5113,1       5110    LPAR12 

This shows that LPAR11 is able to communicate to LPAR12 via unit address 02, but LPAR12 has no device defined on this UA to communicate back.
