Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.12.00.00

For Continuous Access Journal mode package, journal
volumes in PVOL might contain a significant amount of
journal data to be transferred to SVOL. Also, the package
startup time might increase significantly when the package
fails over and waits for all of the journal data to be flushed.
The HORCTIMEOUT must be set long enough to
accommodate the outstanding data transfer from PVOL to
SVOL.
MULTIPLE_PVOL_OR_SVOL_FRAME_FOR_PKG (Default = 0)
This parameter must be set to 1 if a PVOL or an SVOL for
this package resides on more than frames. Currently, only
a value of 0 is supported for this parameter.
NOTE: Future releases might allow a value of 1.
Values:
0—(Default) Single frame.
1—Multiple frames. If this parameter is set to 1, then the
device group must be created with the “data” fence level,
and the FENCE parameter must be set to “data” in this
script.
DTS_PKG_DIR This variable contains the full path name of the package
directory.
WAITTIME Seconds to wait for every “pairevtwait” interval. (Note: do
not set this to less then 300 seconds because the disks have
some long final processing when the copy state reaches
100%).
