Dwight,

Thanks for the help.  When I do a show libr online=0 on 2 of my 3 drives.  I
have checked the errpt but there are no error on the drives.  Is there some
other place I should be looking?  Sorry for my ignorance in this, but this
is the first time we have come across this problem.

Again thanks for all the help.

Rose Campbell
