NAME

       pvcreate - create physical volume for use in LVM volume group

SYNOPSIS

       soft_defects] disk_size] disk_type] pv_path

DESCRIPTION

       The command initializes a direct access storage device (a raw disk device) for use as a physical volume in a volume group.

       If pv_path contains a file system and the option is not specified, asks for confirmation.  The request for confirmation avoids accidentally
       deleting a file system.

       Furthermore, when the option is not specified, the operation is denied if pv_path already belongs to  another  LVM  volume  group,  or  the
       pv_path refers to a disk device under the control of the VERITAS or Oracle ASM Volume Manager.

       After using to create a physical volume, use to add it to a new volume group or to add it to an existing volume group (see vgcreate(1M) and
       vgextend(1M)).

       Disks cannot be added to a volume group until they are properly initialized by

       pv_path can be made into a bootable disk by specifying the option, which reserves space on the physical volume for boot-related data.  This
       is a prerequisite for creating root volumes on logical volumes.	Refer to mkboot(1M) and lif(4) for more information.

   Options and Arguments
       recognizes the following options and arguments:

	      pv_path		  The character (raw) device path name of a physical volume.

	      Read from standard input
				  the  numbers	that  correspond  to  the indexes of all known bad blocks on the physical volume, pv_path, that is
				  being created.  Specify the indexes using decimal, octal, or hexadecimal numbers in  standard  C-language  nota-
				  tion,  with numbers separated by newline, tab, or formfeed characters.  If this option is not used, assumes that
				  the physical volume contains no bad blocks.

				  This option is being retained solely for backward compatibility reasons and is currently ignored.   It  will	be
				  obsoleted in the next HP-UX release.

	      Make a bootable physical volume (that is, a system disk).
				  On  PA-RISC  systems,  pv_path should be the path name for the whole disk.  On Itanium(R)-based systems, pv_path
				  should be the path name for the disk section containing the HP-UX partition (see model(1), getconf(1)).

				  Booting from a volume group version 2.0 or higher is not supported.	Therefore,a  physical  volume  initialized
				  with the option cannot be added to a volume group version 2.0 or higher.

	      Specify the minimum number of bad blocks that
				  LVM  should  reserve in order to perform software bad block relocation.  This number can be no larger than 7039.
				  If not specified, one block is reserved for each 8K of data blocks.

				  This option is being retained solely for backward compatibility reasons and is currently ignored.   It  will	be
				  obsoleted in the next HP-UX release.

	      Effective size of the physical volume to be created,
				  specified in kilobytes (KB).

				  This	option	is only supported on version 1.0 volume groups.  When a physical volume is added to a volume group
				  version 2.0 or higher any value set using the option is replaced with the full size of the disk (up to the maxi-
				  mum physical volume size).

	      Force the creation of a physical volume
				  (thus deleting any file system or volume manager information present) without first requesting confirmation.

				  Warning: The option should only be used as a last resort to over write file system or volume manager information
				  that cannot properly be removed using the commands designed for that purpose.  When  invoked	with  the  command
				  does minimal verification, so care should be taken to assure that the disk is not already in use prior to invok-
				  ing the command.

	      Retrieve configuration information about the physical volume from the file
				  disk_type specifies the device (for example, hp7959S).

				  The disk_type only needs to be specified when fails to get the size from the underlying  disk  driver.   If  the
				  driver successfully returns the size of the device, disk_type is ignored.

   Note
       The user data size of the same physical volume may differ, when initialized by command under different releases of HP-UX.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Create a physical volume on raw device and force the creation without confirmation:

       Create a bootable physical volume for an Itanium-based system on raw device and force the creation without confirmation:

WARNINGS

       If you are using command on an Itanium-based system boot disk, ensure that the specified device special file correspond to the HP-UX parti-
       tion.  For example,

       initializes only the first 2,147,483,647 Kilobytes (2TB - 1KB) of disk space when the disk size exceeds this value.  Disk space beyond this
       point will not be used by LVM.
