I am running within an LPAR on 3 disk units;
unit 123d on volser LIN3
unit 123e on volser LIN4
unit 132f on volser LIN5
Our dasd is a IBM shark model 2105-F20: emulating 3390-3 disk
drives. Our tape drives are on a IBM VTS model 3494-B10: emulating
3590 Magstar tape drives.
I have identified that I ran DFDSS. Data Facility Data Set Services
utility backup to off load the Linux system to tape.
I am trying to restore them to three different disk units.
So, unit 123D is copied to unit 113E, unit 123E is copied to unit
1611, and unit 132f is copied to unit 1242.
Running Standby
123D === 113E
123E === 1611
132F === 1242
On the running system, I IPL from unit 123D. Units 123E and 132F are
managed by LVM. My goal is to have a "hot standby" set of disks that
I can start running if the current "running" system hangs up or
crashes. I have to show that I can recover from a
disaster. So far I have not been able to make that work.
Your assistance is much appreciated.
