From: ADSM: Dist Stor Manager on behalf of Kerry Campbell
I received an unusual message in my TSM report today, that told me there
is one volume unavailable.   

How could this condition occur, how can I locate the unavailable volume,
and in general what is the remedy.



There could be many causes for an unavailable volume, each of which would 
require a different approach to fix and prevent.

The first thing to do is discovery which volume is unavailable; this is easy: 

  Q VOLUME ACCESS=UNAVAILABLE. 

The next thing you need to do is to discovery why it happened. Check your TSM 
server's activity log; do a search for the name of the volume (search='A00001', 
for example). Do a similar search for the string UNAVAILABLE.

Examine the volume itself. Run Q VOLUME A00001 F=D. Are there any read_errors? 
write_errors?
