Subject: ANS0344E (RC2107) Cannot Send data with a zero byte
sizeEstimate.


Hi all 
        have the following messages after completeing a backup untill
recently which was running without a problem.
I was informed by the DBA of the 0 size files, Yesterday when I first
looked into the problem there had been a new drive created and the
variuos file spread across the drives so corrected the SAPofline.opt
file to include the new drive and also the dsm.opt file. Still failed
ran a search through the forum and it suggested upgradeing TSM as its
reading the incorrect file size can`t see why it was necessary.
        Has anyone seen anything similar?
cheers
