Table 24 Parameters for the FCESTABL command (Volume copying) (continued)
Description
Value
Parameter
is completed, and the differential data between the S-VOL and the T-VOL
will be managed. As long as the relationship is maintained, you cannot
update the T-VOL.
The differential data between the S-VOL and the T-VOL will be copied
when you execute the FCESTABL command with INCREMENTAL parameter
specified or you execute the FCESTABL command (Reverse Restore) with
the S-VOL and the T-VOL reversed.
Relationship will be deleted after background copying completes. The
default setting of this parameter is NO.
NO
The relationship remains in effect after background copying completes.
Data can be written to the T-VOL. Subsequent changes are tracked so
YTW
that future operations are performed incrementally. This relationship
continues until explicitly terminated with a Withdraw request.
Note: The target is writable while the incremental relationship is active.
Any writes done to the target during this period are overwritten if a
subsequent increment is done, keeping the target a true copy of the
source. If the relationship is reversed, the changes made to the target are
reflected on the source.
To be specified when the FC Z T-VOL and the Cnt Ac-S Z M-VOL (or Cnt
Ac-J Z P-VOL) are shared.
YES
TGTPPRIM
To be specified when the FC Z T-VOL and the Cnt Ac-S Z M-VOL (or Cnt
Ac-J Z P-VOL) are not shared.
NO
NO is the default setting.
Specifies the device number (device address) of the T-VOL on which you
want to perform the FCESTABL command. To specify this number, use
the TDEVN parameter.
YES
TGTUCB
YES is the default setting.
Specifies the serial number, the CU number, and the LDEV number of the
T-VOL on which you want to perform the FCESTABL command. To specify
this number, use the TARGET parameter instead of TDEVN.
NO
Specifies the serial number, the CU number, and the LDEV number of the
T-VOL on which you want to perform the FCESTABL command.
Serial number, CU
number, LDEV
number of the T-VOL
TARGET
Use this parameter when TGTUCB is NO.
You use the Remote FlashCopy function to establish a relationship.
YES
REMOTE
You do not use the Remote FlashCopy function.
NO
NO is the default setting.
Specifies the Cnt Ac-S Z source device number (device address).
Cnt Ac-S Z source
device number
DEVN
Use this parameter when REMOTE is YES.
Specifies the serial number, the CU number, and the LDEV number of the
S-VOL on which you want to perform FCESTABL command.
Serial number, CU
number, LDEV
number of the S-VOL
SOURCE
Use this parameter when REMOTE is YES.
Specifies the SSID of the CU on which you establish the FlashCopy
relationship.
SSID
SSID
Use this parameter when REMOTE is YES.
Suspends the write operations from the host to all the S-VOL. See
