I just hosed the /usr partition on an RS/6000 (530, AIX 3.1.7).
How? I am still not sure!!! But that comes later, because what
I want to do is fix the thing first.
I was trying to incease the size of the partition using smit,
and I am kind of hazy on the details after that (should take a
look at the smit.log file, but only if I can get the danged thing
fixed first). Anyway, I killed the superblock on the partition.
I thought that I could boot up in single user mode, mkfs on /dev/hd2
(which is where /usr was mounted from), and restore from another
RS/6K machine. But was I mistaken. The manual starts talking about
volume groups and varyoff and varyon on the vg's etc. I thought that
I was following all that, except the manual does not talk of partitions
(with the mkdev command), only physical disks. I would go back into
smit, but the terminal is all screwed up (cannot use the up/down arrow
keys after I booted from the floppies), and that makes smit useless
Help!!! All I want to do is mkfs on /dev/hd2 and I then hopefully
can get the lpp's and other stuff back (and life will be fun).
