For 2105 or 2107 emulation, use the CESTPATH CGROUP option to control freeze. Do not use
the SVP RCU FREEZE option (Mode 104) or the FREEZE option in CESTPATH LINK parameter. If
you use the FREEZE option, the CESTPATH command will be rejected.
CAUTION:
Before issuing the CESTPATH command, you must make sure that the relevant paths
are offline from the host(s) (for example, configure the Chipid offline, or deactivate the LPAR, or
block the port in the ESCD). If any active paths still exist, the add path operation will fail because
the port mode cannot be changed.
Do not use the CESTPATH and CDELPATH commands at the same time as the SCSI path definition
function of LUN Manager. The Fibre Channel interface ports need to be configured as initiator
ports or RCU target ports before the CESTPATH and CDELPATH commands are issued.
“CESTPATH LINK Parameter ” (page 194)
describes the CESTPATH LINK parameter for Fibre Channel
interface.

Fibre Channel Interface
LINK Parameter
Bit 0-3: RCU controller ID
aa
x2-xF: Number stands for RCU controller ID. (x'5' is
specified for XP24000/XP20000 Disk Array.)
First two digits of SAID, see
LINK Parameter (= port) (FRONT CL1)” (page 195)
.
Bit 4-7: FREEZE option
x0:keep the status
x1:Enabled
x2:Disabled
When there are several paths, the same values must be
specified for all the paths.
MCU port number (0x00-0xff)
bb
Second two digits of SAID, see
CESTPAT LINK Parameter (= port) (FRONT CL1)” (page 195)

RCU port number (0x00-0xff)
cc
CU number of the RCU (0x00-0xfe)
dd
If the controller emulation type is 2105 or 2107 (Host Interface: ESCON or FICON), and if you
specify WWN, then syntax is:
CESTPATH
DEVN(X'dev#') PRIM(X'ssid'' WWNN X'lss') SEC(X'ssid' WWNN X'lss')
LINK(X'aabbccdd')
[CGROUP (YES|NO)]
