Hello,
Generally, this error is associated with busy server not having available 
tape drive, to Tape Lib & Legato being out of sync ( if you suspect this 
condition, use nsrjb -HEvvv-after all backup activity has stopped).
Sometime misconfigured pools or hung networker processes could also be 
causing the issue, if the condition is not cleared even when the devices 
are available, restarting networker services & using nsrjb _HEvvv will 
clear your errors.

How do I clear the alerts waiting for writeable media to backup pool??

Does this mean Networker is not recycling media as it should, and if not 
how do I check for this?
