Re: [Networker] Library errors

Hello,
So did you have the "Picker" arm inspected, sometime it can jam and not 
grab the tapes correctly, throwing off Networker, you should pursue a fix 
for this, as it's going to come back time and time again.
Also, i typically use nsrjb -HEvvv  to reset the library in this type of 
situations followed by inventory.

[Networker] Library errors






Here is another incident with the DRIVE_STATUS_NEED_INIT error that was 
resolved without anything too drastic.  Running Networker 7.1.2 on Solaris 
9 with an IBM 3583L72 library.

The incident began during scheduled backups on a Sunday.  By the time 
intervention began on Monday, Networker was requesting manual loading of 
several tapes required for pending saves.  The needed tapes were in the 
library, but Networker failed to load them.  The tape library LCD reported 
SAC: 7300 Code: 0x9102.  This is a "picker failure."  Based on prior 
experience, power cycled the library.  Networker recovered control of 3 of 
the 4 drives and finished the backups.  Networker flagged the fourth 
drive, 3cbn, in service mode.  Monday night's backups succeeded.

On Tuesday, to resolve the state of drive 3cbn, unmounted all the other 
drives in nwadmin.  Found tape #533 in 3cbn.  This tape belongs in slot 
25, but tape #395 was in slot 25, and slot 2 was empty.  Much trial and 
error failed to get Networker back into a consistent state.  Based on what 
finally worked, recommend this procedure for a similar situation:

   1. Use the tape library panel to move the tapes back into their correct 
slots
   2. Run the command
          * nsrjb -H
   3. In nwadmin, correct Networker's inventory by inventorying the 
affected slots
