I'm posting this for a co-worker ...

I'm doing a migration from a 9406-820 to a 9408-M25. I’m doing a Previous Release to Current Release Migration. I’m following the procedure in the V5R4 Backup and Recovery guide chapter 14.

I did a full system backup of the 9406-820 to a 3581 Ultrium 2 tape drive on a 2749 controller card. The backup took 4 hours. After the backup IBM moved the 2749 card and installed it in a 595 expansion unit and connect the 3581 Ultrium 2. We restored the user profiles and cfg information with no problems. We then started the 'RSTLIB savlib(*nonsys) dev(tap02 option(*new) alwobjdif(*all) mbrobt(*all) frcobjcvn(*no) endopt(*leave) omitobj(qofc)'. I calculated that the libraries consist of about 50GB. The restore is restoring about 300 libraries every 5.5 hours. It is running crazy slow and we can’t figure out why.
Any thoughts?

Thanks!

Couple questions come to mind #1 were Accesspaths saved? Where is the 2749 in relation to a disk controller? On the Same BUS or IOP? ( this last item can kill tape performance )
