Re: Device busy
Werner, I got something like that on an OS/390 IPL attempt. The same message, and the devices in question were off line to all other LPARs. I then did a reset clear on the LPAR that I was attempting to IPL, then IPL'ed it again. This time it worked! It appears that the microcode assumed that the IPL was still being attempted, even after the error message was displayed. The RESET CLEAR cleared up the problem. -- John McKown Senior Technical Specialist UICI Insurance Center Applications Solutions Team +1.817.255.3225 -Original Message- From: Werner Kuehnel [mailto:werner.kuehnel;mannheimer.de] Sent: Monday, November 11, 2002 5:05 AM To: [EMAIL PROTECTED] Subject: Device busy I installed Linux (SLES for S/390) onto 3 3390-3 volumes some months ago and got it started from disk.

Re: Device busy
Ouch! That hurts. I'm at a loss. I am fairly sure that a POR of the box will clear the condition. But that is very extreme and likely to get other people a bit upset at you grin. Do you have more than one CEC? Could another CEC have the device tied up? -- John McKown Senior Technical Specialist UICI Insurance Center Applications Solutions Team +1.817.255.3225 -Original Message- From: Werner Kuehnel [mailto:werner.kuehnel;mannheimer.de] Sent: Monday, November 11, 2002 8:17 AM To: [EMAIL PROTECTED] Subject: Re: Device busy Hi John, just tried it, not even with a RESET CLEAR it works.

Re: Device busy
No, just one CEC. I also believe that a POR would do the job, but I fear I won't get the time for a POR :-( I'd like to know if this is a consequence of dynamically changing the access to the devices and OS/390 2.10 or JES3 doesn't really give them free, although they're offline.
