You could also run that link command as root from inside the Linux: Vmcp LINK VMUSER01 210 210 MR
For example, and then chccwdev -e 210 ________________________________________________ Tore Agblad zOpen Teamleader IT Services Volvo Group Headquarters Corporate Process & IT Assar Gabrielssons väg 9 SE-405 08, Gothenburg Sweden E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Dazzo, Matt Sent: den 13 mars 2015 1:04 To: [email protected] Subject: Re: Unable to get device online Thanks, Matt -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Nix, Robert P.

Years at a time), so when you get to a point where you think an IPL is required, take a look at what you¹re doing; likely, you¹ll find that there is a way to do it that doesn¹t demand killing off everything on the system. I didn¹t see a step which included the directxa command. The zVM system doesn¹t look at the source directory at all; you need to convert it to a binary directory and store it in the proper location on the system disk. That¹s what the directxa command does for you. (The DirMaint product would handle the whole situation for you, and guard against finger checks in the process. Please consider using it. {And no; I¹m not an IBM sales rep}) You don¹t even need to restart your Linux guest after adding the minidisk to its directory entry. After properly adding it, issue the command SEND CP <linuxguest> LINK * <vaddr> <vaddr> MR. This will break into CP on the guest and issue the link command, which will add the disk to the configuration. Then you should be able to issue the chccwdev to enable the device, and go on from there. Minimize your downtime, and show the Windows folks just how long a system is supposed to run between boots. -- Robert P.
