Table 21 Parameters for the FCESTABL command (volume copying)
DescriptionValueParameter
Specify the number (device address) of the S-VOL on which you want to
perform FCESTABL command. (This parameter is requied.)
Source device
number
SDEVN
Specify the number (device address) of the T-VOL on which you want to
perform the FCESTABL command. (This parameter is requied.)
Target device
number
TDEVN
Default setting. All the data in the copy range of the volume specified as
the source by SDEVN is background-copied to the volume specified as
COPYMODE
the target by TDEVN. The relationship ends automatically, and all the
data is copied.
Data is not copied in the background. The relationship does not end
automatically even when all the data is copied. To withdraw the
NOCOPY
relationship, use the FCWITHDR command. In the following data, access
occurs. The data subject to read/write processing is copied from the
source to the target before Compatible FlashCopy read/write processing
starts.
• When there is access to write data on the copy source of the specified
area (within the extent)
• When there is access to write data on the copy target of the specified
area (within the extent) or
• When there is access to read data on the copy target of the specified
area (within the extent)
The relationship made by NOCOPY mode is copied in the background.
When all the data are copied, the relationship is released automatically.
NOCOPY2COPY
The path group is not checked. The relationship is established even when
the copy target is online.
YESONLINTGT
Default setting. The path group is checked. The relationship is not
established when the copy target is online.
NO
Establish a relationship including all the tracks in the volume. If you specify
YES for this parameter and COPY for the MODE parameter, the
YESINCREMENTAL
relationship will be maintained even after the background copying process
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 the background copying process is
completed. The default setting of this parameter is NO.
NO
To be specified when the Compatible FlashCopy 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.
YESTGTUCB
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.
