David, Please be aware that if you do not have an external security manager in your z/VM system, CP will provide access to other minidisks based on the minidisk passwords in the CP directory. When you define all for instance all your Linux swap disks as: MDISK 203 FB-512 V-DISK 409600 MR READ WRITE MULTIPLE
That means that anyone who knows the passwords (and that is now the whole community), can, when they have access to your system, do a "CP LINK other_userid 0203 FFFF MW PASS=MULTIPLE" and get the ability to read/write the swap disk of "other_userid". So I would advise to only add minidisk passwords where and when you need them. For instance the "ALL" as read password allows any user-id to link the disk in read mode. A second word of caution, Linux does not like to get a disk in read/only mode when it does not expect so. The linkmode "MR" gives you the disk in read/write mode, unless someone has the disk already linked in write mode, you get the disk then linked in read/only mode. The linkmode you want for Linux guests is "M". That links you the disk in read/write mode, unless someone already has the disk linked read/write, in that case the link fails, something that even Linux user-land tools notice.
