Re: Adding a new 3390 disk
Yes you can, Jim. See the "Working with DASD device driver" section in Chapter 4 of the Device Drivers, Features and Commands" document found on IBM's zLinux web site. To bring a newly attach DASD device online to Linux, you basically just need to issue the chccwdev command: chccwdev -e 0.0.b100 where "b100" is the virtual address of the new DASD volume.

Re: Adding a new 3390 disk
Yes. chccwdev -e [the new disk's virtual device address] lsdasd ...the first will bring the disk online, the second will show you the device address it is attached to (in case you're using the /dev/dasd[a-z]* paths instead of something like /dev/disk/by-path/ccw-0.0.[vdev]) On Thu, Apr 21, 2011 at 1:04 PM, Hughes, Jim wrote: > I've created a new dasd volume for my linux system.

Have you tried using > these keys instead of the ^C sequence? I've used PA2 to generate ^D. I'll try the others. Of course the one thing I'm most interested in, is that the documentation [Documentation/s390/3270.txt) says that I can enter ^n at the end of the line (though from the defkeymap.map file it looks like that should really be just a lone ^ at the end of the line) to send input without a newline at the end. It would make stuff like vim much easier to use from a 3270. Of course, the 3270.txt also refers to non-existant things in /proc which have probably moved to /sys somewhere, to configure the 3270 driver. Hopefully at some point i'll have time to contribute some updates to that documentation, once I sort out what is going on.

There is a chance that the initial ramdisk of your system is being overwritten by the "memory map" that Linux creates at boot time. Try increasing the ramdisk load address in your zipl.conf file (see chapter 37 in * for instructions).

Re: vdisk
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 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.
