WWNN (World Wide Node Name) is the unique number for the controller and is indicated as
shown in “WWNN Example” (page 198).

• The parameter of PRIM and SEC of CDELPATH command are indicated as same as the
parameter of CESTPATH command.
• If the storage system is connected to the former type storage system that does not support the
Fibre Channel interface, a unit check is reported.
“SAID Values for the CESTPAT LINK Parameter (= port) (FRONT CL1)” (page 199) and “SAID Values
for the CESTPAT LINK Parameter (= port) (REAR CL2)” (page 200) give the HP disk array adapter
ID (SAID) values for the CESTPATH LINK parameter.
• The last two digits of the link parameter must specify the logical CU number (00-FE for
XP24000/XP20000 Disk Array, 00-3F for XP12000/XP10000 Disk Array, 00-1F for
XP1024/XP128 Disk Array).
• For 3990 controller emulation, the first two digits can be 00, 01, or 02. This option is unique
to HP RAID storage and controls freeze as follows:
00 = use mode 104
01 = freeze enabled
02 = freeze disabled
• For 2105 or 2107 emulation, the first two digits must be 00. The CGROUP option of the
CESTPATH command is used to control freeze for 2105 or 2107 emulation.
