    NAME
           lvmdiskscan - List devices that may be used as physical volumes
    
    SYNOPSIS
           lvmdiskscan
    	   [ option_args ]
    
    DESCRIPTION
           lvmdiskscan  scans all SCSI, (E)IDE disks, multiple devices and a bunch
           of other block devices in the system looking  for  LVM  PVs.  The  size
           reported  is  the  real	device size. Define a filter in lvm.conf(5) to
           restrict the scan to avoid a CD ROM, for example.
    
           This command is deprecated, use pvs instead.
    
    USAGE
           lvmdiskscan
    	   [ -l|--lvmpartition ]
    	   [	--readonly ]
    	   [ COMMON_OPTIONS ]
    
           Common options for lvm:
    	   [ -d|--debug ]
    	   [ -h|--help ]
    	   [ -q|--quiet ]
    	   [ -t|--test ]
    	   [ -v|--verbose ]
    	   [ -y|--yes ]
    	   [	--commandprofile String ]
    	   [	--config String ]
    	   [	--driverloaded y|n ]
    	   [	--longhelp ]
    	   [	--profile String ]
    	   [	--version ]
    
    OPTIONS
           --commandprofile String
    	      The command profile to use for command configuration.  See
    	      lvm.conf(5) for more information about profiles.
    
           --config String
    	      Config settings for the command. These override lvm.conf set‐
    	      tings.  The String arg uses the same format as lvm.conf, or may
    	      use section/field syntax.  See lvm.conf(5) for more information
    	      about config.
    
           -d|--debug ...
    	      Set debug level. Repeat from 1 to 6 times to increase the detail
    	      of messages sent to the log file and/or syslog (if configured).
    
           --driverloaded y|n
    	      If set to no, the command will not attempt to use device-mapper.
    	      For testing and debugging.
    
           -h|--help
    	      Display help text.
    
           --longhelp
    	      Display long help text.
    
           -l|--lvmpartition
    	      Only report PVs.
    
           --profile String
    	      An alias for --commandprofile or --metadataprofile, depending on
    	      the command.
    
           -q|--quiet ...
    	      Suppress output and log messages. Overrides --debug and --ver‐
    	      bose.  Repeat once to also suppress any prompts with answer
    	      'no'.
    
           --readonly
    	      Run the command in a special read-only mode which will read on-
    	      disk metadata without needing to take any locks. This can be
    	      used to peek inside metadata used by a virtual machine image
    	      while the virtual machine is running.  It can also be used to
    	      peek inside the metadata of clustered VGs when clustered locking
    	      is not configured or running. No attempt will be made to commu‐
    	      nicate with the device-mapper kernel driver, so this option is
    	      unable to report whether or not LVs are actually in use.
    
           -t|--test
    	      Run in test mode. Commands will not update metadata.  This is
    	      implemented by disabling all metadata writing but nevertheless
    	      returning success to the calling function. This may lead to
    	      unusual error messages in multi-stage operations if a tool
    	      relies on reading back metadata it believes has changed but
    	      hasn't.
    
           -v|--verbose ...
    	      Set verbose level. Repeat from 1 to 4 times to increase the
    	      detail of messages sent to stdout and stderr.
    
           --version
    	      Display version information.
    
           -y|--yes
    	      Do not prompt for confirmation interactively but always assume
    	      the answer yes. Use with extreme caution.  (For automatic no,
    	      see -qq.)
    
    VARIABLES
           String
    	      See the option description for information about the string con‐
    	      tent.
    
           Size[UNIT]
    	      Size  is	an  input number that accepts an optional unit.  Input
    	      units are always treated as base two values, regardless of capi‐
    	      talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
    	      input unit is specified by letter, followed by |UNIT.  UNIT rep‐
    	      resents  other  possible	input units: bBsSkKmMgGtTpPeE.	b|B is
    	      bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
    	      megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
    	      e|E is exabytes.	(This should not be confused with  the	output
    	      control --units, where capital letters mean multiple of 1000.)
    
    ENVIRONMENT VARIABLES
           See  lvm(8)  for  information  about environment variables used by lvm.
           For example, LVM_VG_NAME can generally be substituted for a required VG
           parameter.
