Environment

TSM server version 4.2.1.19 running on AIX version 5.1

Windows 2000 server client running SQL server 2000
TSM client ver 4.2.1.26
TDP for SQL 2.2.1


When the backup command is issued, our SQL DBA's are wanting to know the
following and I do not know how to answer.
Can anyone tell me??

Their question:  What is a "virtual device"?  Where is it stored?  Is is on
disk or memory?

        backup log [DSOP_LDAP] to virtual_device =
'TDPSQL-sqladsm-2002102245-20920' with  blocksize=512,
maxtransfersize=1048576




Sometimes the backups fail intermittently with this message...Failures used
to occur alot more until I upgraded all the TSM agents, but it is still
happening intermittently.
