[Networker] Library errors
2008-03-04 16:14:19
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
