Solaris::DeviceTree::MinorNode - Generic minor node of the devicetree


  use Solaris::DeviceTree;
  $tree = new Solaris::DeviceTree( uses => qw( libdevinfo filesystem ) );
  @disks = $tree->find_nodes( type => 'disk' );
  @minor = @disks->minor_nodes;


This class implements generic minor nodes which are generated from Solaris::DeviceTree. The data from all configured data sources containing minor nodes are unified through this class. This is an internal class to Solaris::DeviceTree. There should be no need to generate instances of this class in an application explicitly. Instances are generated only from Solaris::DeviceTree::minor_nodes().


The following methods are available:

$name = $minor->name;

Return the name of the minor node. This is used e.g. as suffix of the device filename. For disks this is something like 'a' or 'a,raw'.

$path = $minor->devfs_path;

Return the complete physical path including the minor node

($majnum,$minnum) = $minor->devt;

Returns the major and minor device number as a pair for the node. The major numbers should be the same for all minor nodes return by a Solaris::DeviceTree::Libdevinfo node.

$type = $minor->nodetype

Returns the nodetype of the minor node. Because we can't find that out by looking at the filesystem we always return 'undef'.

$spectype = $minor->spectype

Returns the type of the minor node. Returns $S_IFCHR for a raw device $S_IFBLK for a block device Both scalars are exported by default.

if( $minor->is_raw_device ) { ... }

Returns true if the minor node is a raw device

if( $minor->is_block_device ) { ... }

Returns true if the minor node is a block device

$node = $minor->node;

Returns the associated Solaris::DeviceTree node. One DeviceTree node can (and usually does) have multiple minor nodes.

$slice = $minor->slice;

Returns the slice number associated with this minor node if it represents a block device.
