persistently bind an autochanger
Hi,
I'm trying to persistently bind an auto changer connected to my server over fiber. the reason I wanna to that because every time I reboot my server the OS gives a different SCSI id to the device files which causes problems with Legato Networker (the backup Application) I have to reconfigure the jukebox all over again which a pain in the ass. the closest I got to solve this problem is by persistent binding on the HBA level. to do that I need to compile a line and put it in the qla.conf the syntax if this line as follows:

hba<#>-SCSI-target-id-<#>-fibre-channel-port-name="<device WWPN>";

I got the hba # from /etc/path_to_inst and the device WWPN from the command inquire but I couldn't get the SCS-target-id.

Could somebody help me to get the SCSI-target-id? or suggest a solution for this problem.

Thanks

tk::callbacks

callbacks(3)						User Contributed Perl Documentation					      callbacks(3)

NAME

       Tk::callbacks - Specifying code for Tk to call.

SYNOPSIS

       One can specify a callback in one of the following ways:

       Without arguments:

	   ... => &subname, ...
	   ... => sub { ... }, ...
	   ... => 'methodname', ...

       or with arguments:

	   ... => [ &subname, args ... ], ...
	   ... => [ sub { ... }, args... ], ...
	   ... => [ 'methodname', args... ], ...

DESCRIPTION

       Perl/Tk has a callback, where Tcl/Tk has a command string (i.e. a fragment of Tcl to be executed).  A perl/Tk callback can take one of the
       following basic forms:

       o   Reference to a subroutine "&subname"

       o   Anonymous subroutine (closure) "sub { ... }"

       o   A method name 'methodname'

       Any of these can be provided with arguments by enclosing them and the arguments in []. Here are some examples:

       $mw->bind($class, "<Delete>" => 'Delete');

       This will call $widget->Delete, the $widget being provided (by bind) as the one where the Delete key was pressed.

       While having bind provide a widget object for you is ideal in many cases it can be irritating in others. Using the list form this behaviour
       can be modified:

       $a->bind("<Delete>",[$b => 'Delete']);

       because the first element $b is an object bind will call $b->Delete.

       Note that method/object ordering only matters for "bind" callbacks, the auto-quoting in perl5.001 makes the first of these a little more
       readable:

	   $w->configure(-yscrollcommand => [ set => $ysb]);
	   $w->configure(-yscrollcommand => [ $ysb => 'set' ]);

       but both will call $ysb->set(args provided by Tk)

       Another use of arguments allows you to write generalized methods which are easier to re-use:

	   $a->bind("<Next>",['Next','Page']);
	   $a->bind("<Down>",['Next','Line']);

       This will call $a->Next('Page') or $a->Next('Line') respectively.

       Note that the contents of the "[]" are evaluated by perl when the callback is created. It is often desirable for the arguments provided to
       the callback to depend on the details of the event which caused it to be executed. To allow for this callbacks can be nested using the
       "Ev(...)" "constructor".  "Ev(...)" inserts callback objects into the argument list. When perl/Tk glue code is preparing the argument list
       for the callback it is about to call it spots these special objects and recursively applies the callback process to them.

EXAMPLES

	   $entry->bind('<Return>' => [$w , 'validate', Ev(['get'])]);

	   $toplevel->bind('all', '<Visibility>', [&unobscure, Ev('s')]);

	   $mw->bind($class, '<Down>', ['SetCursor', Ev('UpDownLine',1)]);
