Our "installnode" script on the management node just watches

Hi All,
I've just been appointed to head an acadmeic computing center, after
an absence from the HPC arena affor 10 years. What conferences/
training/seminars/books/etc would be best for refreshing my awareness
of the technologies and issues?
Thanks!

You might want to take a look at cobbler.
http://cobbler.et.redhat.com/
IIRC, cobbler won't serve a pxe boot image to machine once it's been
provisioned, until you set a flag to reinstall.

For what it's worth, IPMI doesn't work in-band on SuperMicros
Streamline-configured with opensuse 10.3. This fixes it after unloading
the ipmi modules or rebooting:

David,
Are you using LTO-3 tapes? An older gen tape could do it.
Also I have seen instances where /dev/zero is no longer a device but has turned

Hi Perry,
So another question is, how can you reliably test any of this stuff?
It isn't like you can reliably induce single bit errors and see if the
hardware catches them. (A special memory module that let you test
would be a wonderful thing, but I've never even heard of such a thing.)
