Defect Description:
	PHSS_27464:
	Id = HSLco34841
	    Scripts are executed with ".%s" which is "sh" instead
	    of script name.

	Resolution:
	    The dot is removed from function that executes the
	    scripts.

	    Part of SSPUX400_034.

	Id = HSLco35984
	    Attaching fails in environments where alternate links
	    are used because of incorrect instance number counting.

	Resolution:
	    Instance numbers are properly counted if alternate
	    links are used.

	Id = HSLco36041
	    SSEA agent improperly handles "LDEV 0" (unknown logical
	    device).

	Resolution:
	    Logical device resolution is improved by adding
	    additional checking in cases where "LDEV 0" is
	    encountered.

	Id = JAGae22283
	    SSEA agent cannot handle "/" (root) mountpoint when
	    performing a split-mirror backup.

	Resolution:
	    Mountpoint "/" (root) can be used in SSEA split-mirror
	    backup if following is satisfied:

	    1. Root mountpoint is located on an XP disk.
	    2. SSEA_PRESERVE_MOUNTPOINT environment variable is not
	      set to 1 on Backup host.
	    3. SSEA_BACKUP_ROOT_MOUNTPOINT environment variable is
	      set to 1 on Application side.

	    Note: Such backup cannot be used for Instant Recovery!

	    Part of SSPUX400_037.

	PHSS_26363:
	Id = HSLco33370
	    SSEA does not except parameters in pre-exec script and
	    tries to start the string.

	Resolution:
	    SSEA parameters are now correctly parsed.

	    Part of SSPUX400_028.

	Id = HSLco33697
	    The mount API call does not allow some mount options
	    and combinations of mount options.
	    If the disk groups on the R1 host are owned by an user
	    unknown to the R2 host, then the import of the mapfile
	    from R1 to R2 fails.

	Resolution:
	    From now on CLI mount command is used for all mounting.
	    If mounting is in read only mode then no mount option
	    is used. Mounting is considered successful by checking
	    the status of the CLI command and not the returned
	    value of the 'popen()' function.
	    SSEA now parses a mapfile buffer and searches for
	    "user" and "group" entries. If match is found then both
	    values are set to "root". In this way the import of the
	    mapfile on the R2 host is not problematic in case that
	    the diskgroups on the R1 side are owned by a user who
	    is unknown on the R2 host.

	Id = HSLco34238
	    If, during restore, SSEA fails to unmount the only
	    present mountpoint in the session on the application
	    side, it goes on with syncing and splitting the disks.
	    If the only mountpoint present in the session fails to
	    be unmounted on the application side, then the session
	    should fail immediately.

	Resolution:
	    If the only mountpoint present in the session fails to
	    be unmounted on the application side, then the session
	    fails immediately. If there are many mountpoints in
	    the session and not all the mountpoints fail to be
	    unmounted then SSEA skips restore of the disks related
	    to those mountpoints, but proceeds with restore of
	    disks related to the mountpoints that were
	    successfully unmounted.

	PHSS_25966:
	Id = HSLco31734
	    Backup is made in SSEA/split mirror backup environment
	    with the Application host in the cluster. When
	    restoring object on the Backup host (R2), which is not
	    in the cluster the cluster tag (-c y) from the
	    Application host is also restored, so the volume group
	    can not be activated properly.

	Resolution:
	    By default the cluster tag on the Backup host (R2) is
	    disabled with the "vgchange -q n -c n" command. To
	    enable the cluster tag on Backup host, set the new
	    environment variable SMB_CLUS_DEACT=1 in the
	    /opt/omni/.omnirc file.

	Id = HSLco30165
	    During the mapping from logical devices to raw disks
	    the target numbers are incorrectly assigned.

	Resolution:
	    Mapping from logical devices to raw disks
	    is done correctly.

	    Part of SSPUX400_010.

	PHSS_24986:
	Id = HSLco27782
	    Session fails when backup system is left enabled,
	    SSEA_PRESERVE_MOUNTPOINTS is set to 1 in .omnirc
	    file and backup is restarted.

	Resolution:
	    Mountpoint is rechecked becouse it can change.

	Id = HSLco28452
	    If the volume group is located in a cluster on the
	    application side, it is not possible to activate
	    this volume group in "rw" mode on the backup side.

	Resolution:
	    By default volume group on the backup side is activated
	    in read only mode, unless the "Enable the backup system
	    in read/write mode" option is set for the backup.

	Id = NSMex04611
	    Because of the large number of backup volumes agent and
	    backup session manager lost connection to the ssea on
	    the application side in the middle of resolve function.

	Resolution:
	    Buffer concatenation is fixed.
