1. The path that is used before the CESTPATH command is executed, but that which is not specified in the
CESTPATH command is deleted.
2. The path that is used before the CESTPATH command is executed and specified in the CESTPATH
command is maintained.
3. The path that is not used before the CESTPATH command is executed, but that which is specified in the
CESTPATH command is added.
If you specify to delete all paths that are used before the CESTPATH command is executed, the pair
operation might be suspended because the path does not exist temporarily in the processing described
above.
The CESTPATH RESETHP option rejects the host I/O operations. Before you use the RESETHP option of the
CESTPATH command, stop the I/O operations from the host.

Description
Configure Port
(LCP to RCP, or
RCU target to
initiator)
----- ----- If system option mode 114 is OFF, the ports
must be configured using the XP Command
View Advanced Edition Software server or XP
Remote Web Console (or SVP). If system
option mode 114 is ON, the ports are
configured automatically (LCP/RCP to
RCP/LCP, RCU target/initiator to
initiator/RCU target) in response to the
CESTPATH and CDELPATH TSO commands.
However, even if you set ON for system
option mode 114, initiator ports will not
automatically change to RCU target
ports, nor vice versa, when these ports
are in initiator/external mix mode.
For Fibre Channel interface, do not use the
CESTPATH and CDELPATH commands at the
same time as the SCSI path definition function
of LUN Management. The Fibre Channel
interface ports need to be configured as
initiator ports or RCU target ports before the
CESTPATH and CDELPATH commands are
issued.
Add RCU CESTPATH PPRCOPY
ESTPATH
MCU Establishes logical paths from an MCU to an
RCU. The default RCU options are used (see
” PPRC support ” on page 40).
For details on using CESTPATH for TC390A,
see ” CESTPATH ” on page 161.
Delete RCU CDELPATH PPRCOPY
DELPATH
M-VOL Deletes all active paths between an MCU and
an RCU.
