The mkdef -u option was added in xCAT 2.8, which is why you are getting the
"invalid option" error. What the -u flag does is set default paths for
your imagedir and other attributes based on the "old"
arch/profile/provmethod search algorithms.
The easiest way to create a new osimage in xCAT 2.7.8 is to first run
copycds (if you have not done so in a recent version of xCAT) which will
create standard osimage defs corresponding with the distro you just copied.
Sounds like you have already done that if you can see a full def for your
centos6.2-x86_64-install-vm. So, then one way to make a new image similar
to that one is:
lsdef -t osimage centos6.2-x86_64-install-vm -z > /tmp/newosimage.def
vi /tmp/newosimage.def
## make sure to change at least the object name
## for diskless and statelite image, also make sure to set a
unique rootimgdir so you don't accidently overwrite an existing diskless
image
## change any other attrs you would like to customize for this
osimage, especially: template, pkglist, otherpkglist, pkgdir, otherpkgdir
cat /tmp/newosimgage.def > mkdef -z
Then to make sure it's what you want:
lsdef -t osimage -l <newosimage>
If you're not sure what some of the attrs might be, if you have a node that
is using the old arch/profile/provmethod, you can do:
lsdef <node> --osimage
and it will include the template, pkglist, etc., attrs in the node
definition output.

Subject: [xcat-user] osimage dabbling before upgrading to 2.8
Hi all,
I'm on xcat 2.7.8 right now and preparing for 2.8.x. I'm trying to play
with osimages a bit but can't seem to define a new one. I see that
several already exist with 'lsdef -t osimage'. I can see the details of
one with, say, 'lsdef -t osimage centos6.2-x86_64-install-vm'. But I
can't make a new one...
$ mkdef -t osimage centos6.5-x86_64-install-vm -u imagetype=linux
osarch=x86_64 osname=Linux osvers=centos6.2 profile=vm provmethod=install
Error: Invalid option..
Should I just go ahead and upgrade to 2.8.x first? I want to get my
bearings straight on osimage before I am forced to migrate. I don't want
to disrupt my users.
