Re: New Tape units
We use ZARA so had to supply our own. Depending on what the 'supplied' exits do you may or may not want to modify them. YMMV but it would make sense to understand what they are coded to do or not do. I forgot about the 30 CIOS option, It wasn't appropriate for our environment when we installed. We were using the bulk station and at one time were ejecting 400-500 tapes a day and a similar number of inserts (about half the usable slots for our 3490's). Not recommended but it worked for us at the time. We are now down to 10-20 after upgrading to 3592's. We used to have trouble with the 3490-F1A's but most of that was due to our dirty/old tapes.

New Tape units
Our year end 'sweet deal' from IBM was a tape 'robot'. The IBM 3494 system. We don't do near enough tape processing to justify the VTS. Two robots, actually, one for our production site and one for the BR site. This system is to replace our two antique 3490 ACL units and two aged 3590 ACL units. Wanna buy some tape drives, cheap? ;-) We are using DFSrmm as our tape control software. All tapes are strictly for backup. No input tape allowed. And we don't plan to change that. The next phase is to leverage the two robots to do each others offsite backups. We are being told that the library system is 100% SMS controlled. We have had robots in the past, but had never heard this as a requirement. It this your experience? We intend to rework all of what little tape processing we have to exploit the new units. Does anyone have some thoughts for a migration plan? Did you have to invent some processing, such as off site tape ejects? Any other things we should be aware of? Thanks, the very best of the new year to all. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
