unfortunately, that's the way it works.  if you get the message to take 
out the tapes and click ok (or return if cli), and you click ok before 
taking out the tapes, it puts the tapes back into the robot and returns a 
message that the eject was aborted.  it's nice that they gave it a try, 
but i don't know what they were thinking when they put the logic in this.

I have found that ejecting multiple tapes, even with 4.5, is easier using 
a script...
- look at location in library with vmquery (in case it fails to eject, 
because it will still logically eject even with error)
- print " " | vmchange -res -e
- check for error codes and logically move back into library with vmchange 
if eject failed

(currently without big 
patch set)


I've noticed one annoying behavior and one potential bug in using vmchange 
to eject tapes. 
1. A bug (?) where the volume database will be inconsistent with the tape 
locations if the tapes are not acutally removed from the mailslots when 
prompted.
2. An annoying "feature" where I can't seem to run this multi-eject 
command non-interactively - I want to leave the tapes in the mailslots 
while the command completes. 
I'd like comments and/or fixes to both.  Details follow... 
--------------- 
I've been doing this in v3.4 to eject tapes (which still works in v4.5): 
vmchange -res -m <tapenum> -mt dlt -e -sec 1 

This command seems to work in v4.5 but I've noticed that they've supplied 
a new multi-eject form, too.  Ideally, I'd like to stay with the 
documented command set.
        vmchange -res -multi_eject -w -verbose 
        -rn <robot_number> -rt <robot_type> -rh <robot_control_host> 
        -ml <media_id:media_id:...:media_id> 
I can use this to eject tapes - however, it wants me to complete the 
process by physically removing tapes from the mailslots when prompted 
while I want to leave them there (so I can go on to page the tape apes, 
etc. to fetch and carry).  If I hit <return> to complete the command 
(without removing tapes), the tapes are automatically replaced back into 
the library slots but the volume database remains incorrect, showing them 
as out-of-library.  If I interrupt the command while waiting at the "press 
return" prompt, then it does what I want except that I had to interact 
with it to achieve this.
[root]#vmchange -res -multi_eject -w -verbose -rn 0 -rt tld -ml 
CG0131:CG0132 
*** Eject volume batch #1 is ready to be removed *** 
        remove 2 volume(s) from media access port(s) of robot number 0 now 
        (press <RETURN> to continue)  <<<<< I hit return here without 
removing 
                                      <<<<< the tapes. Afterword tldtest 
shows 
                                      <<<<< them as back in the main 
library slots 
Slot# MediaID Barcode     MAP_Element#  Batch  Status 
  124 CG0131  UNKNOWN                1      1  Eject aborted. 
   66 CG0132  UNKNOWN                2      1  Eject aborted. 

tldtest shows them as not in the mailslots but returned back into the 
library slots: 
[root] #echo "s i" | tldtest -r /dev/sg/c1t3l0 
Opening /dev/sg/c1t3l0 
Enter tld commands (? returns help information) 
Address 10, import_enabled = 1, export_enabled = 1, access = 1 
  except = 0, import_export = 0, full = 0 
Address 11, import_enabled = 1, export_enabled = 1, access = 1 
<snip> 
[root] #echo "s s" | tldtest -r /dev/sg/c1t3l0 
Opening /dev/sg/c1t3l0 
Enter tld commands (? returns help information) 
<snip> 
slot 32 (addr 1031) contains Cartridge = yes 
Source address = 10 
Barcode = CG0131 
<snip> 
slot 66 (addr 1065) contains Cartridge = yes 
Source address = 11 
Barcode = CG0132 
<snip> 

Now I checkout the volume database and it shows them incorrectly as out of 
library (field 9 is slot num): 
[root] #vmquery -a -w | grep CG013[12] | awk '{print $1,$9}' 
CG0131 - 
CG0132 - 

Update the inventory to make them appear again: 
[root] #/usr/openv/local/update_inventory    <<<<< wrapper around 
"vmupdate" 
## Please wait... 
##   Updating robot 0. 
## Done. 
[root] #vmquery -a -w | grep CG013[12] | awk '{print $1,$9}' 
CG0131 32 
CG0132 66 

If I interrupt the vmchange command in mid-eject, right when it says 
"press return", then it'll leave the tapes in the mailslots.
[root] #vmchange -res -w -multi_eject -verbose -rn 0 -rt tld -rh europa 
-ml CG0131:CG0132 
*** Eject volume batch #1 is ready to be removed *** 
        remove 2 volume(s) from media access port(s) of robot number 0 now 
        (press <RETURN> to continue)^C 
[root] # 

The library agrees that the tapes are in the mailslots (visually 
confirmed, too) 
[root] #echo "s i" | tldtest -r /dev/sg/c1t3l0 
Opening /dev/sg/c1t3l0 
Enter tld commands (? returns help information) 
Address 10, import_enabled = 1, export_enabled = 1, access = 1 
  except = 0, import_export = 0, full = 1 
  Source address = 1031 
  Barcode = CG0131 
Address 11, import_enabled = 1, export_enabled = 1, access = 1 
  except = 0, import_export = 0, full = 1 
  Source address = 1065 
  Barcode = CG0132 
<snip> 

Volume database is correct: 
[root] #vmquery -a -w | grep CG013[12] | awk '{print $1,$9}' 
CG0131 - 
CG0132 - 

What I want is this second behavior - ejected tapes, correct volDB, etc. 
to occur non-interactively, without having to hit break at the command 
line.  Is this just a Veritas ploy to get us to purchase Vault?
