value. The default Continuous Access link timeout value is
5 minutes (300 seconds). A suggested value for
HORCTIMEOUT is 360 seconds.
During package startup, the default startup timeout value of
the package is set to NO_TIMEOUT in the package ASCII
file. However, if there is a need to set a startup timeout
value, then the package startup timeout value must be
greater than the HORCTIMEOUT value, which is greater than
the Continuous Access link timeout value:
Pkg Startup Timeout > HORCTIMEOUT >
Continuous Access link timeout value
For Continuous Access Journal mode package, journal
volumes in PVOL may contain a significant amount of journal
data to be transferred to SVOL. Also, the package startup
time may increase significantly when the package fails over
and waits for all of the journal data to be flushed. The
HORCTIMEOUT should 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 P9000 or XP frames.
Currently, only a value of 0 is supported for this parameter.
NOTE: Future releases may 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.
PKGDIR If the package is a legacy package, then this variable
contains the full path name of the package directory. If the
package is a modular package, then this variable contains
the full path name of the directory where the Metrocluster
xpca environment file is located.
WAITTIME Seconds to wait for each “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%).
The following table describes AUTO_* variables settings and the package’s startup behavior that
are supported with Metrocluster with Continuous Access XP version A.05.00 or later on HP-UX
11.0 and 11i or later systems.
