WWNN (World Wide Node Name) is the unique number for the controller and is indicated as shown in
Figure 69.
Figure 69 Example of WWNN
NOTE: The parameter of PRIM and SEC of CDELPATH command are indicated as same as the parameter
of CESTPATH command.
If the subsystem is connected to the former type subsystem that does not support the fibre channel interface,
a unit check is reported.
The following table gives the XP1024/XP128/XP12000/XP10000 system adapter ID (SAID) values for the
CESTPATH LINK parameter.
• The last two digits of the link parameter must specify the logical CU number (00-1F for an
XP1024/XP128/XP12000/XP10000, 00-0F for an XP256).
• For 3990 controller emulation, the first two digits can be 00, 01, or 02. This option controls freeze as
follows:
00 = use mode 104
01 = freeze enabled
02 = freeze disabled
