Regarding DR procedure, perhaps you should focus on the service at hand not on OS based restore ?

Since you have a two identical machines on two locations, you can just have a kickstart file with additional configuration (additional packages, users, kernel limits etc.)

Then you can basically get the DR OS setup layer in several minutes via automated install.

Since you have OEL, i will presume that the service on that machine would be oracle database.

So using tools on your disposal (Storage based cloning, tape restore, oracle utilities via network rman, exp etc.) you can easily clone or restore just the service, in this case database on the DR site.

Hicks, looks like we might be OK on the /dev restore as looking around it seems it can be rebuilt using udev rather than needing to be restored.

Peasant, the rest of the process is OK, it is only the OS restore I am worried about (because its really the only bit I am responsible for). The rest is using tried and tested methods (albeit on a different OS).

Kickstart is one option i was thinking of, but then i would have to manually install Netbackup and run a netbackup restore to ensure that all the changes that have been made since the original kickstart was done get implemented. I was looking at having both options available, as it is quicker to untar a tarball on an already built OS than it is to build using kickstart and netbackup I would have only reverted to kickstart solution in the case of the OS going wrong for the reasons above.
