EXACTLY! -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Dave Jones Sent: Friday, November 30, 2007 10:50 AM To: [email protected] Subject: Re: Formatter for/Linux Minidisk from CMS
I think the problem Jim is trying to avoid is the fact that Linux at boot time will generate a ton of less than useful console messages if it finds that some of it's dasd devices don't have at least some low level format already in place....lots and lots of "CCW command rejects" and i/o errors. If you have a number of Linux images all generating these console messages at boot time, your automated VM console management can become overwhelmed.....
