Not exactly.  It makes it available to CP for that z/VM guest.  To make it
accessible to CMS, you would do an "access" command (if it were CMS
formatted).  To make it available to Linux, you would need to go through the
"echo add device range=xxx > /proc/dasd/devices" routine.

For us "non-VM" aware users, can I assume that the command "CP LINK" causes
the new root disk to be available -- aka "online", to the original or
(old/source) system?

Subject: Re: Moving root to a new volume


Here is a list of the steps I did to move my root disk. YMMV.  Good Luck.

   Shut down my target system
   From a second system, CP LINK to the old root system and the new root
   disk
   dasdfmt -b 4096 -v -f /dev/dasdd             [This prepares the disk to
   receive the data. ]
   fdasd -a -b 4096 /dev/dasdd
   mke2fs -j -b 4096 /dev/dasdd1
   mount old root system as /oldroot
   mount new disk as /mnt
   cp --preserve=all --recursive /oldroot/* /mnt/   [There are two dashses
   before preserve and recursive]
   cd /mnt/etc
   Create the zipl.ths.conf file below.
   cd /mnt/sbin
   ./zipl -c /mnt/etc/zipl.ths.conf             [You want to execute the
   copy of zipl on the target system]
   cd /                                   [You need to get out of /mnt so
   you can umount it.]
   umount /mnt
   umount /oldroot
   CP DET the two minidisks
   Modify the directory of the targe system to swap the addresses of the
   old and new root disks.
   Boot the target system

<newroot>/etc/zipl.ths.conf:

# Generated by YaST2
[defaultboot]
default=ipl

[ipl]
target=/mnt/boot/zipl
image=/mnt/boot/kernel/image
ramdisk=/mnt/boot/initrd
parameters="dasd=201-20F root=/dev/dasda1"

<newroot>/etc/fstab:

/dev/dasda1          /                          ext3        defaults
            1 1
/dev/dasdc1          /home                ext3        defaults
            1 2
/dev/dasdb1          /usr                       ext3        defaults
            1 2
devpts                     /dev/pts             devpts      mode=0620,gid=5
      0 0
proc                         /proc                    proc       defaults
            0 0

Toto, I have a feeling we're not in the mainframe world any more.
