Issued to: Description
Configure Port
(RCU target
to initiator)
— — If system option mode 114 is OFF, the ports must be configured
using the TC-MF software. If system option mode 114 is ON, the
ports are configured automatically (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.
Note: For fibre-channel interface, 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.
Add RCU CESTPATH PPRCOPY
ESTPATH
MCU Establishes logical paths from an MCU to an RCU. The default RCU
options are used.
Delete RCU CDELPATH PPRCOPY
DELPATH
M-VOL Deletes all active paths between an MCU and an RCU.
RCU Status CQUERY/PATH
S
PPRCOPY
QUERY/
PATHS
MCU Displays the status of all paths for the CU specified by the DEVN
parameter. TCz supports the optional FORMAT/UNFORMAT and
VOLUME/PATHS parameters.
Async Options — — MCU/RCU The default TCz async options are used.
Add Group — — MCU Must be performed using the TCz software. The group options are
selected during add group.
Group Status — — MCU/RCU Must be performed using the TCz software.
Delete Group — — MCU Must be performed using the TCz software.
Add Pair CESTPAIR
(MODE=COPY)
PPRCOPY
ESTPAIR
M-VOL Establishes a TCz 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). TCz
supports the optional MODE, PACE, and CRIT parameters. The
MSGREQ parameter defaults to NO (not applicable to TCzA).
Suspend Pair CSUSPEND PPRCOPY
SUSPEND
M-VOL or
R-VOL
Suspends a TCz pair (or TCzA group). TCz supports the optional
PRIMARY parameter. See WARNING below on the QUIESCE
parameter.
Delete Pair
(to MCU)
CDELPAIR PPRCOPY
DELPAIR
M-VOL Releases a TCz pair (or TCzA group) from the MCU.
Delete Pair
(to RCU)
CRECOVER PPRCOPY
RECOVER
R-VOL Releases a TCz pair (or TCzA group) from the RCU.

Information
CQUERY/
VOLUME
PPRCOPY
QUERY/
VOLUME
M-VOL or
R-VOL
Displays the TCz & TCzA pair status of the volume. TCz supports
the optional FORMAT/UNFORMAT and VOLUME/PATHS
parameters.
Resume Pair CESTPAIR
(MODE=
RESYNC)
PPRCOPY
ESTPAIR
M-VOL Resynchronizes a TCz pair (or TCzA group), and sets the TCz initial
copy options and pair options. TCz supports the optional MODE,
PACE, and CRIT parameters.
