can't LINK the real dasd address as a virtual address; you can LINK to MDISKs (try HELP CP LINK); see my 2nd linux-390 reply to your post; RE-LINK isn't needed after re-boot; Can't do the guest's LINK from userid MAINT unless you use secuser/SCIF or other methods, for starters enter the LINK command from the guest's VM console using #CP LINK ... The #CP is needed so so z/VM's CP sees and acts on the command and not linux; think of #CP as an escape sequence. good luck

Can I LINK the real DASD device address AS a virtual address? LINK * 513D 800. I asked this because up to this point I have presented the DASD to the Linux guest via the USER DIRECTORY entry as VIRTUAL addresses so I would like to stay consistent when I LINK them dynamically while the guest is active. If the guest is re-booted will the LINKED DASD is be there after the re-boot or would I need to re-LINK? Does it matter whether I issue the LINK via the MAINT user or does it have to be done from the guest itself? This is my first attempt at z/VM and z/Linux so if the questions sound elementary until I sort this all out, I apologize.

Updating the directory for a virtual machine has no effect on the virtual= machine, until the virtual machine is next logged on. For a virtual machine that is already logged o= n, you will have to log off and log back on again. If you want the virtual machine to stay logged on, you can either ATTACH = the device to the virtual machine, or ATTACH it to SYSTEM and then LINK to it from the virtual mach= ine.
