While the "sleep 1" was in clone.sh, the "sync" was not. I inserted the sync after the dd and clone.sh is working again and not hanging on the chccwdev -d.
Thanks for the assist. ________________________________ Judson West Systems Programming Team Teradata Corporation -----Original Message----- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of Michael O'Reilly Sent: Friday, November 13, 2009 10:20 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: chccwdev never returning on SLES 11 Judson, The IBM development team is investigating this problem.

It does not appear to hang if I perform the cloning steps, from the book, manually. I searched the list and caught a thread about this from July 09. Any update on why this is happening? ________________________________ Judson West Systems Programming Team Teradata Corporation All words above are not actual sentences but random letters, spaces and the occasional punctuation.
