Package Attributes for Continentalcluster with Continuous Access for P9000 and XP

This appendix lists all Package Attributes for Metrocluster with Continuous Access for P9000 and XP. HP recommends that you use the default settings for most of these variables, so exercise caution when modifying them:

AUTO_FENCEDATA_SPLIT	(Default = 1)
	This parameter applies only when the fence level is set to
	DATA, which will cause the application to fail if the
	Continuous Access link fails or if the remote site fails.
	Values:
	0 – Do NOT startup the package at the primary site. Require
	user intervention to either fix the hardware problem or to
	force the package to start on this node by creating the
	FORCEFLAG file. Use this value to ensure that the SVOL
	data is always current with the trade-off of long application
	downtime while the Continuous Access link and/or the
	remote site are being repaired.
	1 – (DEFAULT) Startup the package at the primary site.
	Request the local disk array to automatically split itself from
	the remote array. This will ensure that the application able
	to startup at the primary site without having to fix the
	hardware problems immediately. Note that the new data
	written on the PVOL will not be remotely protected and the
	data on SVOL non-current. When the Continuous Access
	link and/or the remote site is repaired, you must manually
	use the command “pairresync” to re-join the PVOL and
	SVOL. Until that command successfully completes, the PVOL
	will NOT be remotely protected and the SVOL data will not
	be current. Use this value to minimize the down time of the
	application with the trade-off of having to manually
	resynchronize the pairs while the application is running at
	the primary site.
	If the package has been configured for a three data center
	environment, this parameter is applicable only when the
	package is attempting to start up in either the primary (DC1)
	or secondary (DC2) data center. This parameter is not
	relevant in the recovery cluster or the third data center. Use
	this parameter’s default value in the third data center.
AUTO_NONCURDATA	(Default = 0)
	This parameter applies when the package is starting up with
	possible non-current data under certain Continuous Access
	pair states. During failover, this parameter will apply when
	the SVOL is in the PAIR or PFUL state and the PVOL side is
	in the PSUE, EX_ENORMT, EX_CMDIOE or PAIR (for
	Continuous Access Journal) state. During failback, this
	parameter will apply when the PVOL is in the PSUS state
	and the SVOL is in the EX_ENORMT or EX_CMDIOE state.
	When starting the package in any of the above states, you
	run the risk of losing data.
	Values:
