Variable Functions
ShadowImage command
environmental variables
$ HORCC_MRCF: Sets the execution environment of the ShadowImage commands. The
selection whether the command functions as that of Hitachi TrueCopy or ShadowImage is made
according to this variable. The HORCM is not affected by this variable. When issuing a Hitachi
TrueCopy command, do not set the HORCC_MRCF variable for the execution environment of
the command. When issuing a ShadowImage command, set the environmental variable
HORCC_MRCF=1 for the execution environment of the command.
Note: The following environment variables are validated for USP V/VM and USP/NSC only, and
are also validated on TC-TC/SI cascading operation using “-FHOMRCF [MU#]” option. To
maintain compatibility across RAID storage systems, these environment variables are ignored by
9900V/9900, which enables you to use a script with “$HORCC_SPLT, $HORCC_RSYN,
$HORCC_REST” for USP/NSC on the 9900V/9900 storage systems.
