HPUX::Ioscan - Perl function to handle HPUX ioscan command

This module works on top of the HP-UX command ioscan. It forks a process to run the ioscan command and parses its STDOUT. The result is returned in a hash.

This module is quite basic but it may be interesting if you need to write administration program on HP-UX.

You may call ioscan several time in your program without any problem sicne the result is cached. Only the first call to ioscan will actually run the ioscan command. (But you may override the caching of the result)

ioscan ( [force => 1] )

Will return the result of the ioscan command. The ioscan command is run the first time or if the force parameter is set to 1.

This function returns a hash ref. The keys of the hash are all the hardware paths found on your system.

The value is another hash ref containing these keys :

See ioscan(1M) for the meaning of these keys.

The value of device_files is an array containing the name of the device files attached to the hardware path.

Heres an example of the structure returned for 1 disk:

This module takes the output from the ioscan command and hashes it into an object. You can then access its attributes via its AUTOLOADED methods i or other custom methods.

It utilizes the Storable module for persistance so once called you can then recall it without re-running the command and/or wait for the network by setting persistance from 'new' to 'old'.

Remote node access is supported via remsh or ssh. ssh is highly recommended since the ioscan command that the script runs needs root.

new

The main object constructor that returns the hash refrence. The keys of the hash are all the hardware paths on your system. It accepts the following paramters:

The value is another hash ref containing there keys :

See ioscan(1M) for the meaning of these keys.

Heres an example of the structure returned for 1 disk:

Partial Ioscan Object (disk only). Illustrates the optional extended diskinfo option.

get_disk_controllers()

traverse()

get_all_disks_on_controller(controller=>'1/2/3/4.5')

get_device_hwpath(device_name=>'/dev/dsk/c4t3d0')

get_device_diskinfo(device_name=>'/dev/dsk/c4t3d0', attribute=>'size')

The iocan command is run in blocking mode and may indeed block for several seconds on big systems.
