In the case of a ibm3494 with 4 tape drives, what happens in the case of a
restore as far as the way TSM utilizes those drives? Will it take advantage
of the fact that there are 4 tape drives and mount 4 tapes to restore
quicker (assuming data is on 4 different tapes)?

For example what if I have an Oracle database with ½ a Terabyte of data
backed up to my TSM server. Obviously this data is going to be across
multiple tapes. Now when it comes time to do a restore, how many drives will
it use to do the restore or what factors determine this?

Thanks
