- I have a serious compatibility problem caused by the
- difference between DEC, Sun, etc. and the way IBM AIX
- does things.
-
- I have an AIX 3.2 system that had the information on
- 2 hards disks totally wiped out. Having a Sun/DEC
- background, my backup procedure is based on the
- rdump/restore utilities. This is what I used to do
- in Suns when my system disk was damaged:
-
- (1) boot the miniroot.
-
- (2) use the format command that comes in the SunOS
- installation CD ROMS to repartition the (new) disk
- to the precise sizes that it had before the crash.
- (BTW: suppose I didn't write those down, how can I get
- that information from tape?).
-
- (3) use 'restore' to bring my data back.
-
- (4) if one of the restored partitions was the root partition,
- use 'installboot' to put the boot blocks needed for
- booting.
-
- My problems is that the only step that maps to AIX
- is (3). I've been working with IBM support and they
- don't seem to be familiar with steps (1-4). All they
- know is 'smit' and logical volumes and volume groups.
- It is as if in the IBM view, rdump and restore are not
- supposed to be used on an entire disk, but only for
- individual files.
-
- My question is: Given that I have my backup tapes,
- how can I find out what were the partitions of
- the hard disk (the precise sizes) before the crash?
-
- Does AIX have something functionally equivalent to
- Sun 'format' or 'dkinfo'?
-
- thanks,
