Symptoms:
	PHSS_24291:

	1. When the device pair state is PVOL-PSUS and
	SVOL-PSUS(SSWS), the MC code allows the package
	to failback to the primary site without doing a
	pairresync.  The end result is the application
	uses the old copy of the data.

	2. When the device pair state is EX-ENORMT and
	SVOL-PSUS(SSWS), the MC code does not allow the
	package to start on the SVOL side.

Defect Description:
	PHSS_24291:

	1. The problems occur because the version A.02.00 of
	MetroCluster code does not specificcally check for
	the SSWS state. It assumes that the devices were
	in suspending state due to a manually split.  So
	when the package fails back to PVOL side, the code
	didn't do a pairresync to get the new data from the
	SVOL side.

	2. The problem occurs because the version A.02.00 of
	MetroCluster code does not specifically check for
	the SSWS state.  When the package is starting on
	the SVOL side, the code assumes this is the first
	time the package fails over to the secondary site
	and tries to do a takeover.  The takeover didn't
	happen and the package fails to start.
