Path Name: /hp-ux_patches/s700_800/11.X/PHSS_27785

Symptoms:
	PHSS_27785:

	1. When using MetroCluster/SRDF A.04.10 (or earlier
	   versions) with SRDF Consistency Groups and using
	   EMC Symmetrix SymCLI V4.3 and later, the
	   MetroCluster/SRDF logic will disallow the package
	   to startup on any node. The following message is
	   written to the package's control script log file:

	   "The minimum revision of SymCLI is not met. You need
	   at least version "V4.1". Please fix the problem before
	   proceeding. Exiting and disabling package restart."

	2. Independent of SymCLI versions, when MetroCluster/SRDF
	   A.04.00 and A.04.10 use SRDF Consistency Groups, the
	   MetroCluster/SRDF code extracts the wrong field for the
	   device group type (RDF1 or RDF2) and will disallow the
	   package to startup on any node. The following message
	   is written to the package's control log file:

	   "Cannot determine which SRDF device (R1 or R2) is in
	   use by this package. Probable error in control script
	   customization. Exiting and disabling package restart."

Defect Description:
	PHSS_27785:

	1. The version string format for SymCLI V4.3 and later
	   changed so that MetroCluster/SRDF logic thinks the
	   version is lower than it really is. Therefore, the
	   version check fails and disallows the package to
	   startup on any node.

	2. The MetroCluster/SRDF code for A.04.00 and A.04.10
	   extracts the wrong column in "symrdf -cg" output for
	   determining which device group type is being used. Since
	   MC/SRDF cannot determine whether the consistency group is
	   on the R1 or R2, the MetroCluster/SRDF logic fails and
	   disallows package to startup on any node.

Enhancement:
	No
