Can you show the tape names in the desired order?

    Hi Thanks for the response, the tape list is already in the arrary @tapes_to_eject. Then i tried to sort them like this:

    #my @tapes_to_eject=sort @_ ; my @tapes_to_eject=@_ ; #my @tapes_to_eject=sort { substr($a, 1) <=> substr($b, 1)} @_ +; # Test #print "@_";

    Then I run them through the eject command:

    `/usr/openv/volmgr/bin/vmchange -res -multi_eject -w -rn $robot_num - +rt tld -rh $robot_host -ml $\@_[0]:$\@_[1]:$\@_[2]:$\@_[3]:$\@_[4]:$\ +@_[5]:$\@_[6]:$\@_[7]:$\@_[8]:$\@_[9]:$\@_[10]:$\@_[11]:$\@_[12]:$\@_ +[13]:$\@_[14]:$\@_[15]:$\@_[16]:$\@_[17]:$\@_[18]:$\@_[19]:$\@_[20]:$ +\@_[21]:$\@_[22]:$\@_[23]:$\@_[24]:$\@_[25]:$\@_[26]:$\@_[27]:$\@_[28 +]:$\@_[29]:$\@_[30]:$\@_[31]:$\@_[32]:$\@_[33]:$\@_[34]:$\@_[35]:$\@_ +[36]:$\@_[37]:$\@_[38]:$\@_[39]:$\@_[40]:$\@_[41]:$\@_[42]:$\@_[43]:$ +\@_[44]:$\@_[45]:$\@_[46]:$\@_[47]:$\@_[48]:$\@_[49]:$\@_[50]:$\@_[51 +]` ;

    but the do not come out sorted

      #my @tapes_to_eject=sort { substr($a, 1) <=> substr($b, 1)} @_;
      Well, if you outcomment the sort there's little chance it will sort. And you may want to do a string compare instead of a numeric compare.
