System is running RHLE 6.4. It's a physical server. When I boot the system OS hung at some point. I rebooted the system in rescue mode and generated the sosreport. But I am not sure how to retrieve sosreport from this sytem?

Any suggestion will be appreciated.

You mean you have the report file and don't know how to get it off that system? Red Hat's rescue system should have networking and tools like scp; just copy the file to a remote system. I might be wrong, or you might not get networking to work; perhaps a USB key could help then. Or copy the sosreport to a disk file, then boot your system from a Live CD/DVD/stick and use networking to copy it somewhere.

Or perhaps I misunderstand your question?

Edit: I just found this Red Hat document about sosreports in rescue mode, but without a support contract, I can't read it: https://access.redhat.com/solutions/2872

Also where does your OS hang? There might be ways to revive it without the sosreport, e.g. booting into single user mode or booting into the initramfs.

Well thank you very much. I configured the network interface and scp'd to another host. Thank you once again. THIS IS RESOLVED.
