Table 21 Parameters for the FCESTABL command (Volume copying) (continued)
Description
Value
Parameter
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 Compatible FlashCopy T-VOL and the Cnt Ac-S
Z P-VOL (or Cnt Ac-J Z P-VOL) are shared.
YES
TGTPPRIM
To be specified when the Compatible FlashCopy T-VOL and the Cnt Ac-S
Z P-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
FREEZE
ACTION
Only the copied part from the S-VOL to the T-VOL of the established
relationship will be copied. You reverse the S-VOL and the T-VOL of the
relationship.
FRR
Establishes the relationship without using the Preserve Mirror FlashCopy
function. If PRESERVEMIRROR is not specified, NO is set by default.
NO
PRESERVEMIRROR or
PRESMIR
Establishes the relationship using the Preserve Mirror FlashCopy function.
If the relationship cannot be established, the command is rejected.
TGTPPRIM(YES) must be specified as well.
