We are running TSM V5.2.2.1 for Solaris on a Solaris 2.8 server. I am not a 
Unix admin. The Unix support team loaded and licensed Veritas Quick I/O. 
According to the TSM Performance tuning guide you either want to use Quick I/O 
or RAW volumes when defining DB, LOG, or Disk pool volumes on Solaris. Because 
our Oracle Administrators use Quick I/O we decided to use it on our TSM server. 
I was under the assumption that all you have to do is install Quick I/O and 
everything will be faster. Due to the fact that we are currently getting 
extremely poor performance when backing up to disk as opposed to tape I believe 
there must be more we have to do in order to get the bennifits of Quick I/O.

Is anyone out there running TSM on a Solaris Server using Quick I/O? If so what 
did you have to do in order to get Quick I/O to speed things up?
