in thread remove 16 Zeros

Folk, i need help again :-(

how do i save this value (pvid) to a sub function in perl? there are keys defined in the sub function and they are pushed and later prints in html:

push(@{$lsmap_slots{$key}}, $svsa); push(@{$lsmap_slots{$key}}, $physloc); push(@{$lsmap_slots{$key}}, $vtd); push(@{$lsmap_slots{$key}}, $lun); push(@{$lsmap_slots{$key}}, $backing); push(@{$lsmap_slots{$key}}, $bdphysloc); push(@{$lsmap_slots{$key}}, $status);

how do i push pvid in this sub function?>

i know, i have to read but Perl is very heavy for me at the Moment.

Kind Regards

    What you have posted isn't a function :/

    but you don't save values to a sub function, functions are not storage places, functions are not variables

    you save values into variables, you save values into scalars, arrays and hashes

    you pass variables (like references) to functions

    http://perldoc.perl.org/perlintro.html#Writing-subroutines

    Now you could be asking how to push $pvid as well? But that seems kinda obvious, you just copy/paste what you have and make the var $pvid

    So first you need to figure out what you want and then communicate that effectively to us

    push @{ $lsmap_slots{$key} }, $svsa, $physloc, $vtd, $lun, $backing, $bdphysloc, $pvid, $ollyollyoxenfree, $status;

      thank u for response. I have a OS related output from

      command, which is getting information from client via a

      Management Server. This Information is about

      VirtualDisks.

      Each Client has more than one path to a disk to avoid SPOF.

      to identify Disks mapped from a Virtual IO Server, the

      command from output shows information about Disks:

      virtual adapter

      Adapter location

      Virtual Taregt Device

      logical Unit

      backing device (if it is a disk)

      and Status (if it is available)

      In this command i am not abot to find pvid. so i have to

      define another output and define the pvid(physical volume identifer.

      this ouput gives me a line like this

      pvid 00c6ae3a2ea7ba7a0000000000000000

      this is a unique ID of Disk

      So what i need is, to get the Physical Volume ID from Disk and print it to the html based Table. Thanks
