Oracle 11gR2 Node Addition into Cluster post Host Reimage

When a host is reimaged, we assume that there will be no Oracle software on it and the addNode process will take care of adding Oracle stuff to reimaged host.When these errors were encountered, noticed that the reimaged host had the Oracle Home ( GI andDatabase with all contents. !his implies that Oracle Homes were copied o"er from the a"ailable host

to this reimaged host.#o, first thing I did was remo"e the Oracle Home folders on the reimaged host.

$ctual steps should be %

&. Delete the information about reimaged host from the in"entor' of e isting node and also the O)*

a. )learing the O)* ke's for reimaged host
