CESTPATH command
Use the CESTPATH command to establish remote paths from an MCU to an RCU when using fiber
cable. CESTPATH also allows you to enter a Controller ID for the RCU.
Requirements
• Fibre Channel ports must be configured as initiator ports or RCU target ports before the
CESTPATH and CDELPATH commands are issued.
• When system option mode 114 is enabled, ports are configured automatically when the
CESTPATH and CDELPATH TSO commands are run (RCU target/initiator to initiator/RCU
target). If this system option mode is disabled, ports must be configured using Remote Web
Console.
• With Fibre Channel, do not use the CESTPATH and CDELPATH commands at the same time
as the LUN Manager SCSI path definition function.
CESTPATH command syntax
Use the following syntax for the CESTPATH command:
CESTPATH DEVN (X'dev#) PRIM (X'ssid' serial# X'lss') SEC (X'ssid' serial#
X'lss') LINK (X'aabbccdd') [CGROUP (YES|NO)]
When WWNN (World Wide Node Name) is specified, use the following syntax:
CESTPATH DEVN (X'dev#) PRIM (X'ssid' WWNN X'lss') SEC (X'ssid' WWNN
X'lss') LINK (X'aabbccdd') [CGROUP (YES|NO)]
NOTE:
• For CDELPATH, the syntax for both PRIM and SEC is the same as CESTPATH.
• A unit check is reported on earlier model storage systems that do not support the syntax above.
CESTPATH parameters
When fibre is used, CESTPATH parameters are the following.
