We've been using a TS7720 for 3 years now but we are NOT in a grid which makes for some interesting operational procedures. The virtual volumes are copied/stacked to physical volumes using TAPECOPY from OPENTECH which works just fine. Our only problem so far is restoring the data for HSM ML2 and backup tapes at our DR site since the restore must be to an equivalent volume type and except for another VTS there aren't any 3490's that hold 4GB of data. The other problem with only 1 TS7720 is applying maintenance to the machine. When the CE needs to install software updates it often takes 3-4 hours and that means NO tape access for that period.

Any problems when use VTS 7720? anyone can share? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
