You could also create a USB flash drive with the appropriate version of OneFS and then boot and reimage each node.  Search for: OneFS: How to reimage a node using a USB flash drive and How to create a bootable image of OneFS on a USB flash drive  on EMC Support.  Cheers,Matt
Hi All,    We've got a set of four Isilon nodes, previously configured as a cluster, but now pretty much inconsistent. We would like erase or re-configure the configuration, so that we could start from scratch by recreating the cluster. Right now our network config too is in shambles and  OneFS file system too doesn't mount.  Could one direct me to some documentation/video guidance on a lead, as to how to achieve this. We needn't worry about the data in these nodes.  Regards Naleendra
