Workaround

1. On the Sun Management Center server, change to the directory holding family files.

   # cd /opt/SUNWsymon/classes/base/console/cfg

2. Create a symbolic link to the closest available family-j.x file.

   For example, if the missing file line read ...missing for sun4u-Sun-Ultra-450-family-j.x..., create a link from sun4u-Sun-Enterprise-450-family-j.x to sun4u-Sun-Ultra-450-family-j.x.

   # ln -s sun4u-Sun-Enterprise-450-family-j.x sun4u-Sun-Ultra-450-family-j.x

3. Exit the console, and restart it.
