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
The following methods are available:
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'.
Return the complete physical path including the minor node
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.
Returns the nodetype of the minor node. Because we can't find that out by looking at the filesystem we always return 'undef'.
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.
Returns true if the minor node is a raw device
Returns true if the minor node is a block device
Returns the associated
Solaris::DeviceTree node. One
DeviceTree node can (and usually does) have multiple minor nodes.
Returns the slice number associated with this minor node if it represents a block device.
