vxvmboot

vxvmboot(1M)															      vxvmboot(1M)

NAME

       vxvmboot - prepare Veritas Volume Manager volume as a root, boot, primary swap or dump volume

SYNOPSIS

       /sbin/vxvmboot [-b|-d|-r|-s] [-v] -o offset -l length rawpath

       /sbin/vxvmboot -v rawpath

       /sbin/vxvmboot -c

DESCRIPTION

       The  vxvmboot  command updates information in the LABEL file for the lif disk specified by the pathname of its character (raw) device node,
       rawpath.  The volume at the specified offset and length becomes the boot, root, primary swap or dump volume when the system is next booted.

       This command is normally invoked by the vxbootsetup utility.

OPTIONS

       -b	 Specifies the volume type as a boot volume with name standvol.

       -c	 Is used to update the /stand/rootconf file with the offset and length of the rootvol. The usage is slightly different when the -c
		 argument  is  used.  The rawpath argument is not used with this invocation. Instead the path of the boot device is extracted from
		 the /stand/bootconf file.  Also, the -o and -l arguments are not used to specify the offset and length.  Instead, the offset  and
		 length of the rootvol are obtained from the LIF LABEL file on the boot device.

		 The  -c  option would normally be used in the sbin/ioinitrc script to update the /stand/rootconf file, when the boot disk is VxVM
		 rootable.

       -d	 Specifies the volume type as a dump volume with name dumpvol.

		 If a dumpvol volume exists on the specified disk, the extent information from this volume is used. If no such volume exists,  the
		 extent information of the swap volume is used instead, and swapvol performs the dual role of swap device and dump device.

       -l length Specifies the length of the volume in units of 1024-byte blocks.

       -o offset Specifies the start of the volume as the number of 1024-byte blocks from the beginning of the disk.

       -r	 Specifies the volume type as a root volume with name rootvol.

       -s	 Specifies the volume type as a swap volume with name swapvol.

       -v	 When  used with one of the options -b, -d, -r or -s, displays the contents of the updated LABEL file.	Otherwise, this option may
		 be used to display the contents of the LABEL file on the specified lif disk.

	      Note: The -b, -c, -d, -r and -s options are mutually exclusive.  If more than one of these options is specified, the  vxvmboot  com-
	      mand exits without performing any operation.

ARGUMENTS

       rawpath	 Specifies the pathname of the character (raw) device node for the lif disk.
