Yes, 1988. We had abundant spinning DASD since that's the only kind that
existed. It was a small MVS shop that IBM provided ($$) generously.
Usual questions:
1. Do you have enough disk? No guessing allowed.
2. Is the tape mount scenario driving this plan?
2. Will it complicate your DR?
3. Will it complicate your routine non-DR backups?
I know you asked that below but every shop has its own methods of backup
for DR and non DR. Without
intimate knowledge of your current backup methods.......speculation.
All in all I think it's an excellent idea, subject to niggling details of
course.

We are considering changing from a mix of Tape and Disk for HSM
functions.
So ML2 would go away or be very reduced
ML1 would be expanded
BACKUP and ABARS would be directed to DASD.
Has anyone done this?
If so, what were some of the experiences? Did you find the increase in
dasd
requirements were exponential? Or were they an easy slope (that is not
any
quick growth)
Did you find any issues with constantly adding dasd? Or could you
stabilize
the HSM needs.
Did it provide better support for Business Recovery or Disaster Recovery?
Any performance issues?
Thanks for any input
