Table 56 Parameters of PPRC TSO Commands Supported by FlashCopy Mirror Version 2
Command Parameter Description
FCESTABL SDEVN Source device number. Specify the number (device address) of the S-VOL on
which you want to perform FCESTABL command. (This parameter is essential.)
TDEVN Target device number. Specify the number (device address) of the T-VOL on which
you want to perform FCESTABL command. (This parameter is essential.)
MODE COPY = 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 the target
by TDEVN. The relationship ends automatically and the FlashCopy Mirror Version
2 pair is deleted when all the data is copied.
NOCOPY = Data is not copied in the background. The relationship does not end
automatically even when all the data is copied. To withdraw the 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 FlashCopy
Mirror Version 2 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).
ONLINTGT YES = The path group is not checked. The relationship is established even when
the copy target is online.
NO = Default setting. The path group is checked. The relationship is not
established when the copy target is online.
EXTENTS Specifies the extent (copy range) by setting the same starting and ending
addresses of the source and target with CCHH (cylinder and head numbers).
From the copy source, the specified data is copied to the same offset position on
the copy target. Up to 32 extents can be specified. When EXTENTS is not
specified, the data on all the tracks are copied.
XTNTLST Specifies the extent (copy range) by setting the starting and ending addresses of
the source and the starting and ending addresses of the target with CCHH
(cylinder and head numbers). From the copy source, the specified data is copied
to a different offset position on the copy target. Up to 32 extents can be specified.
When XTNTLST is not specified, the data on all the tracks are copied.
