[Lustre-discuss] mounting an OST from another node attached to a fibre channel switch

[Ron]

Which section of which manual? Please.  I.e are you talking about:
Part No. 820-3681-10
Lustre manual version: Lustre_1.6_man_v1.10
December 2007

4.2.3.2 Running the Writeconf Command
and/or 4.2.3.3 Changing a Server NID

Our MGS is not changing nodes, but the OSTs are.
Is there really just one simple MGS only operation?
Those sections do not quite fit (to my way of thinking, which is
in the process of being adjusted :}

Thanks,
Ron
