1. You will have to boot from AIX Base CD to do the restore of the H70
MKSYSB to the H50 or you would have to have all the device drivers installed
on the H70 for the H50 ( bad idea ).
2. Those map files are only for rootvg you can select yes; but unless they
are exactly the same location adapter and all it will not use them. So it
does not really matter.
3. What does the SSA layout have to do with the MKSYSB unless your rootvg
is on SSA or your Oracle installation in the rootvg ( bad idea too ) ? If
not, they have nothing to do with each other... If the oracle volume group
is separate or on SSA then apples and oranges.
4. Only issues might be your TSM nodename and location of your TSM
server...

Subject: DR test-need help w/concepts & overall procedures << 2nd time
I sent this last week and did not receive a response then.
Comments -- Please ??
Enviro:
H50, SSA 7133-020, AIX 4.3.3.10, Oracle Hotspare, filesystems optimized
w/map file for SSA placement
H70, SSA 7133-D40, AIX 4.3.3.10, Oracle Production 8i
TSM 4.2.2.10, Magstar MP 3570 library
Management has finally decided to test our DR capability with existing H50
HotSpare server.
Not having done DR before, but having seen the DR messages on this listserv
for a year now, I need to be able to put the H70 mksysb onto our H50.
We already have customized/optimized the SSA disks w/map files on the H50
now, so there is going to be a difference in filesystem size and placement
between the H70 Production, and the H50 HotSpare.
Questions:
1) How does using the H70 mksysb tape on the H50 work as far as devices on
the H50? Does it load in drivers specific for the H50?
2) On making the H70 mksysb tape, there is a field for "Create map files"
(Y or N). What does this do and should I set this to Y or N on the H70
mksysb tape?
Remember-I have map files for the H50 that need to be used the filesystem
placement.
3) How do I use the existing H50 SSA filesystem map files when using the
H70 mksysb tape?
4) DR procedure: (overview)
- Load H50 w/H70 mksysb. Get AIX OS running. TSM program files should also
be here to run TSM.
- Reload Oracle data files via TSM onto H50 filesystems.
- Have DBA configure Oracle to run on H50.
