I need to restore aix servers (from the ground up) for disaster recovery at
Sungard in a couple months using netbackup. I have never done this and have
no test servers to work with so I have to go into it blindly. Our netbackup
master server is windows and the media server is solaris 8. I was able to
get useful information on restoring solaris from Netbackup support but they
say they don't have similar detailed information on aix restores.
I know I will have to boot from cdrom and install a rootvg on the second
disk on a server. Then I know I have to install the netbackup client on the
second disk. Then make sure it communicates on the network and reach the
master server, that is fine. What happens next is what I'm unclear about.
For the solaris directions, you run newfs to create a filesystem on the
first slice of the first disk: newfs -v /dev/rdsk/c0t0d0s0 , then make a
directory like /recdisk to restore to. For aix, I guess you would do the
same step but what would be the (exact) syntax? Wouldn't the first disk
have to added to the rootvg in order to create a filesystem on it? Then
how would you designate which disk? Would it be something like: crfs -v
jfs -g rootvg -a size=65536 -m /recdisk -d /dev/hdisk1? -- hdisk1 because
hdisk0 is already used? Won't you eventually have a screwed up odm then?
Then, once that is created you restore via netbackup. Since the master
server is windows, I won't be able to restore from there, I have to use the
java client interface from the solaris media server (I guess) to the
alternate /recdisk location. On the solaris instructions, it says you MUST
have 'rename hard links' turned on and 'rename soft links' turned off. Is
that still true with aix?
Then you're supposed to install the boot block on the original disk. I'm
guessing that would be something like: bosboot -a -d /dev/hdisk1 ?
Then I have no idea what to do next. In solaris, you create a /recdisk/proc
directory and run these two commands: disks -r /redisk/ and devfsadm
-r /recdisk/
I have no idea what the eviqualent of that would be in aix. And I'm sure
there are other things you need to do in aix. I imagine one of them is
changing the boot list with something like: bootlist -m normal hdisk1
And then I guess reboot? Do you have to manually mount root since is was
restored to /recdisk?
Any docs that anyone has that shows step-by-step command line by command
line for the aix restores would be sooo grreat. I have one for solaris that
I would be happy to give in exchange.
