A. ``WISS" refers to the media index. Greg Feczko's email (17 Sep 1999) explains what the acronym means. WISS stands for Wisconsin Storage System, a program Legato purchased from (if I remember correctly) a college in Wisconsin, that was modified for Legato's use. The reason they chose it was because its highly tuned for insertions. Similar error messages: unable to start nsrd

various save errors

Dr Watson error A. Legato Tech Bulletin #352 also sets out a number of steps to follow to fix corruption with media indices. K. Scott Rowe's answer (24 Mar 2000) also has some tips: You need to run nsrck -F to 'attempt' to fix the error, which generally occurs only when the database grows over 2GB. If this does not work, you then have two options:


  1. Delete the index.db and run nsrck -c, this generates a blank index.db for you, and you can then run your backups.
  2. Run and mmrecov to restore the last good database. Please run nsrck -F on this database as well, just to make sure everything is clean for Networker.


Also see the ``Index Corruption" section for further details about solving this problem. For a Solaris-specific cause, see 7.4.4, Why does Networker seem to hang?
