NAME

       vxse - Storage Expert rules

SYNOPSIS

       /opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] check

       /opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] info

       /opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] list

       /opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] run [attribute=value...]

DESCRIPTION

       Storage	Expert	consists  of a set of simple commands that collects VxVM configuration data and compares it with "best practice."  Storage
       Expert then produces a summary report that shows which objects do not meet these criteria and makes recommendations for VxVM  configuration
       improvements.

       These  user-configurable tools help you as an administrator to verify and validate systems and non-optimal configurations in both small and
       large VxVM installations.

       Storage Expert components include a set of rule scripts and a rules engine.  The rules engine runs the scripts and produces  ASCII  output,
       which  is  organized and archived by Storage Expert's report generator.	This output contains information about areas of VxVM configuration
       that do not meet the set criteria.  By default, output is sent to the screen, but you can redirect it to a file using standard  UNIX  redi-
       rection.

KEYWORDS

       check	 Lists the default values used by a rule's attributes.

       info	 Describes what a rule does.

       list	 Lists the attributes of a rule that can be set.

       run	 Runs a rule.  If one or more attribute-value pairs are specified, these override the values set in the defaults file.

OPTIONS

       -d defaults_file
		 Specifies an alternate default attribute-values file to the standard file, /etc/default/vxse.

       -g diskgroup
		 Specifies the disk group to be examined instead of the default disk group (see vxdg(1M)).

       -v	 Specifies verbose output format.

EXAMPLES

       Note:  The  executable  rule  files  are located in the directory, /opt/VRTS/vxse/vxvm.	These examples assume that this directory has been
       added to the PATH variable.

       Discover what the vxse_stripes2 rule does:

	      vxse_stripes2 info

       Display the attributes that are available for the vxse_drl1 rule:

	      vxse_drl1 list

       Display the default values of the attributes for the vxse_stripes2 rule:

	      vxse_stripes2 check

       Run the vxse_volplex rule on the mydg disk group:

	      vxse_volplex -g mydg run

       Run the vxse_drl2 rule on the mydg disk group with the value of the large_mirror_size attribute set to 30MB:

	      vxse_drl2 -g mydg run large_mirror_size=30m

       Run the vxse_srl2 rule using the default attribute values that are set in the file mydefaultsfile:

	      vxse_drl2 -d mydefaultsfile -g mydg run

FILES

       /etc/default/vxse   Standard attribute values file for vxse rules.

       /opt/VRTS/vxse/vxvm Directory containing executable rules.

NOTES

       See the "Using Veritas Storage Expert" chapter in the Veritas Volume Manager Administrator's Guide for a description of the rules and their
       attributes.

NAME

       vxsplitlines - show disks with conflicting configuration copies in a cluster

SYNOPSIS

       vxsplitlines [-g diskgroup] [-c daname]

DESCRIPTION

       If  you	import	portions  of a disk group on different systems, this can lead to conflicting configuration copies on the disks of the disk
       group.

       If the configuration information in a disk group is ambiguous, it may not be possible for Veritas Volume Manager to determine which config-
       uration	copy  is  most up-to-date.  (This is usually termed a serial split brain (SSB) condition when it occurs in a cluster.)	You cannot
       import a disk group in this state unless you specify which disk's configuration copy to use.

       You can use the vxsplitlines command to see which disks in a disk group have conflicting configuration copies,  and  use  this  information
       together with your knowledge of the history of the disk groups' usage to determine which configuration copy is most valid.

       The output from vxsplitlines displays the vxdg commands that you can run to import the disk group using the available configuration copies.
       The -o selectcp option of the vxdg import command is used to select the configuration copy to use for the import.

OPTIONS

       -c daname Display the SSB IDs for each disk that are stored in the configuration copy on the disk specified by its disk access name.

		 Note: Although the SSB IDs for some disks may match, this does not necessarily mean that those disks' configuration  copies  have
		 recorded  all	the configuration changes. When viewed from some other configuration copies, the SSB IDs of the same disks may not
		 match.

       -g diskgroup
		 Specifies the disk group. If a disk group is not specified, the default disk group is used as determined from the  rules  on  the
		 vxdg(1M) manual page.

EXAMPLES

       Display the disks on each side of the split in the disk group newdg:

			vxsplitlines -g newdg

       Display the SSB IDs stored in the configuration copy on disk c2t4d0:

			vxsplitlines -g newdg -c c2t4d0

NOTES

       The vxsplitlines is primarily intended to be used with private disk groups, but it also works with shared disk groups.

       The version number of the disk group must be 110 or greater.
