Symptoms:
	PHSS_28230:
	Id = HSLco36130  SR: H555008604
	    Disk resolving on backup host is very slow.

	Id = HSLco37123  SR: H555008788
	    Some of the volume groups cannot be activated.

	Id = HSLco38080  SR: H555008995
	    Snapa backup fails with:

	      "[Normal] From: SNAPA@<backup_host> ""  Time: <time>
		ABORTED SNAPA-Backup Agent on <backup_hostname>."

	PHSS_27450:
	Id = HSLco32002  SR: H555006949
	    SNAPA agent has poor resolving performance.

	Id = HSLco33554  SR: H555007503
	    debug.log file gets filled with messages:

	      "mm/dd/yy hh:mm:ss  SNAPA.10149.0
	       ["<source file, version>":<line>] A.04.10 <VERSION>
	       [<function>] /dev/rdsk/c?t?d? is not a VA disk!"

	Id = HSLco35468  SR: H555008436
	    SNAPA agent abnormally ends while resolving backup
	    objects on application system.

	Id = HSLco35801  SR: H555008538
	    Backup using VA integration fails with:

	      "[Major] From: SNAPA@<hostname> ""
	       Time: mm/dd/yy hh:mm:ss
	       Failed to split the BC pair of LDEV
	       <ldev#>, SEQ# , MU#"
	       [<function>] /dev/rdsk/c?t?d? is not a VA disk!"

Defect Description:
	PHSS_28230:
	Id = HSLco36130
	    All devices on backup host are being queried.

	Resolution:
	    Only VA disks are queried when gathering disk
	    information.

	Id = HSLco37123
	    If the application host is MC/SG system, then volume
	    groups on the backup host cannot be activated in
	    read/write mode.

	Resolution:
	    Volume groups on backup side are marked "not-clustered"
	    before activation in read/write mode. To prevent such
	    marking set SMB_CLUS_DEACT=1 in /opt/omni/.omnirc file.
	    Note: SMB_CLUS_DEACT=1 means the volume group is marked
	    as clustered.

	Id = HSLco38080
	    New HP17 VA firmware is not working with the API v.2.2.

	Resolution:
	    Snapa agent is rebuilt with new API v.2.3.

	    Part of SSPUX410_051.

	PHSS_27450:
	Id = HSLco32002
	    One of the API's called during resolving takes up
	    to 45 seconds to complete. Calling this API multiple
	    times causes poor performance.

	Resolution:
	    Resolving algorithm is improved.

	    Part of the SSPUX410_003.

	Id = HSLco33554
	    Every time SNAPA agent encounters non-VA disk during
	    resolving phase, a message is logged in debug.log file.

	Resolution:
	    Debug range for message is changed and the message is
	    not logged.

	Id = HSLco35468
	    When SNAPA agent tries to dump buffer containing
	    information about rawdisks and LUN's to session output,
	    it ends abnormally if buffer is too big.

	Resolution:
	    Information about rawdisks and LUN's is being dumped to
	    session output in pieces keeping the buffer within
	    prescribed size.

	    Part of SSPUX410_026.

	Id = HSLco35801
	    SNAPA agent parses the output of "vgdisplay -v <vgname>"
	    and collects logical volume names. It collects physical
	    volume name as well in environments where PVG's are
	    configured.

	Resolution:
	    Parsing is terminated when "PVG name" token is
	    encountered.
