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.

NAME

       vxpfto - set Powerfail Timeout (pfto)

SYNOPSIS

       vxpfto -g diskgroup -t timeout

       vxpfto [-g diskgroup] -t timeout  volume_list

       vxpfto [-g diskgroup] -o pftostate={enabled|disabled}

       vxpfto [-g diskgroup] -o pftostate={enabled|disabled} volume_list

DESCRIPTION

       Powerfail Timeout is an attribute of a SCSI disk connected to an HP-UX host (see the pfto(7) man page).	The vxpfto command sets the Power-
       fail Timeout interval on a set of Volume Manager disks, either all disks in a disk group, or all disks underlying the volumes listed.

       The first form of the command sets the same PFTO value for all the disks in the specified VxVM diskgroup.

       In the second form, all disks underlying the given list of volumes are selected, optionally restricted by the disk group specified with the
       -g option.  If you specify a diskgroup, any volume in the list not belonging to the diskgroup is ignored.

       Use  the  -o  pftostate	option	to disable or enable PFTO. By default, PFTO is enabled.  You can enable PFTO either on all disks in a disk
       group, or on all disks underlying the volumes listed.

       If you invoke vxpfto without arguments, it displays a usage message.

OPTIONS

       -g diskgroup
		 Specifies the disk group for the operation, either by disk group ID or by disk group name.

       -o pftostate={enabled|disabled}
		 Enables or disables the use of PFTO for IO.

       -t timeout
		 Specifies the PFTO value in seconds.  The value must be zero or a positive integer.  Zero  represents	the  system  default  PFTO
		 value.  The default value depends on the disk driver controlling the disk device.

       volume_list
		 A list of VxVM volume names. List items must be separated by white-space.

EXIT CODES

       vxpfto  returns a zero if successful.  If it encounters an error, vxpfto exits and displays a message on standard error. Defined exit codes
       are:

       0    Success.

       1    No PFTO value specified.

       2    No diskgroup or volume list specified.

       3    Illegal PFTO value specified.

EXAMPLES

       Set the PFTO value on all disks in disk group testdg to 100 seconds:

	      vxpfto -t 100 -g testdg

       Set the PFTO value to 50 seconds on all disks underlying volume01 and volume02 in disk group testdg:

	      vxpfto -t 50 -g testdg volume01 volume02

       Set the PFTO value to 300 seconds on all disks underlying volume01 and volume02, even though they are not in the same disk group:

	      vxpfto -t 300 volume01 volume02

       Disable PFTO on all disks in disk group testdg:

	      vxpfto -g testdg -o pftostate=disabled

       Enable PFTO on all disks underlying volume01 and volume02i in disk group testdg:

	      vxpfto -g testdg -o pftostate=enabled volume01 volume02
