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 SVP mode 114 is OFF, the ports must be
configured using the Command View XP
management station or XP Remote Web
Console (or SVP). If SVP 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.
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 41).
For details on using CESTPATH for TC390A,
see ”CESTPATH” on page 150.
Delete RCU CDELPATH PPRCOPY
DELPATH
M-VOL Deletes all active paths between an MCU and
an RCU.
RCU Status CQUERY/
PATHS
PPRCOPY
QUERY/
PATHS
MCU Displays the status of all paths for the CU
specified by the DEVN parameter. TC390
supports the optional FORMAT/UNFORMAT
and VOLUME/PATHS parameters.
Asynchronous
Options
----- ----- MCU/RCU The default TC390A options are used (see
”PPRC Support” on page 41).
Add Group ----- ----- MCU Must be performed using the TC390
software. The group options are selected
during add group (see ”Adding Consistency
Groups (Add CT Group)” on page 99).
Group Status ----- ----- MCU/RCU Must be performed using the TC390 software
(see ”Viewing Consistency Group Status (CT
Group Status)” on page 97).
Delete Group ----- ----- MCU Must be performed using the TC390 software
(see ”Deleting Consistency Groups (Delete CT
Group)” on page 101).
Add Pair CESTPAIR
(MODE=
COPY)
PPRCOPY
ESTPAIR
M-VOL Establishes a TC390 pair and sets the initial
copy and pair options (copy mode =
synchronous or asynchronous only, priority =
0, CFW data = copy to R-VOL, DFW to R-VOL
= not required). TC390 supports the optional
MODE, PACE, and CRIT parameters. The
MSGREQ parameter defaults to NO (not
applicable to TC390A). For details on using
CESTPAIR for TC390A, see ”CESTPAIR” on
page 152.
