Terry, After adding MDISKs to the linux guest's User directory entry and doing the DIRECTXA the running guest can't see or use the new MDISKs until you do CP LINK commands to the MDISKs from the guest's 3270 console or via secuser or the other ways. #CP Q V DASD from the guest's console will display the disks currently in the virtual machine's configuration, #CP LINK * newvdev newvdev will link the guest to its new MDISK, then do the #CP Q V DASD to verify success. Your remarks about ATTACH-ing a disk to the guest and surprise at finding it unformatted sounds like the disk should have been instead ATTACHed to SYSTEM and then the guest LINK-d to its new MDISK.

I need to give this guest some more ECKD DASD. I want to do this dynamically. As far as I knew to accomplish this I should only need to add the devices to the User Directory bring that new Directory online (DIRECTXA USER). At this point on the Linux side they need to do some things to see the new device. Now I did the above steps once to add three ECKD devices and on the Linux side they were able to see them, everything looked look. However there was a need to add one more ECKD DASD to the Linux guest. I went through the same exact steps and this time they could not see the device. Is there anything else that I need to do on the z/VM side to make this work? I have made sure that the devices are formatted and that they are attached to SYSTEM. I will mention one thing. I was able to ATTACH the REAL DEVICE ADDRESS as VDEV 806(In my case). Once I did that the Linux folks were able to see the ECKD device. However they showed up on the Linux side as un-formatted. This is not the way it is suppose to work. I should need to ATTACH them. I even added the new devices to the CONF file that the RedHaT Kick Start reads and did a Kick Start. The devices still did not show up. Any suggestions would be appreciated. I am going to also post this on the z/ Hi I am running z/VM 5.3 with a RedHat 4.6 z/Linux (Kernel level 2.6.9-67) guest.
