Sharing and maintaining SLES 10 SP2 Linux under z/VM 19
CLONERW EXEC Clones a read-write machine from S10GOLD
MNT2GOLD EXEC Copies the S10RWMNT minidisks to S10GOLD 11Bx
RO2GOLD EXEC Copies disks from S10ROGLD to S10GOLD 21Bx
RO2GOLD2 EXEC Copies disks from S10ROGLD to S10GOLD2 21Bx
MNT2TST EXEC Copies disks from S10RWMNT to S10RWTST
TST2MNT EXEC Copies disks from S10RWTST to S10RWMNT
LNXCLONE
A Linux system that contains of the tools used to create the S10ROGLD machine i.e. all shared
root images. It also contains the DVD images of all shared software for other Linux guests to
mount through NFS.
Following are the important files in /usr/local/sbin/ on this system:
boot.findself On first boot, this script is run to set up the proper host name and IP of
the new Linux guest. The IP address and host name are read from a
parameter file specific to the virtual machine, on its 191 disk.
boot.rootfsck.diffs A diff file used to update the boot.rootfsck for read-only Linux guests
fstab.ror A modified /etc/fstab copied to all new read-only Linux guests
cloneprep.sh A script that removes extraneous files before cloning
mnt2rogld.sh Copies read-write disks from S10RWMNT to S10ROGLD.
offliner.sh A script to verify all minidisks are off-line and not linked before running
mks10rogld.sh.
S10RWMNT
The backup/mirror of S10RWTST. This machine's binaries are used to create shared-root gold
disks as well as read-write gold disks. There is usually no reason to boot and login to this
virtual machine. Once the binaries are stable, copy to the 11Bx series of minidisks using
RW2GOLD EXEC on CMSCLONE.
S10RWTST
All new RPMs and other changes are tested on this machine. Once tests have been made,
the cloneprep.sh script is run and the system is copied to S10RWMNT using the TST2MNT EXEC
on CMSCLONE.
If there is a need to roll-back the system from S10RWMNT because a change is not desired, that
can be accomplished using the MNT2TST EXEC on CMSCLONE
S10ROGLD
The Linux system on this virtual machine is created by the mnt2rogld.sh script residing on
LNXCLONE. It is essentially a read-only Linux guest. Here you can login before cloning a real
read-only guest to see if the read-only system is running properly. Testing new read-only
binaries and applications should be done from this virtual machine.
Once the binaries for read-only machines are good (stable), they should be copied to S10GOLD
using RO2GOLD EXEC on CMSCLONE.
S10GOLD
This virtual machine defines two series of minidisks to store the golden images. It cannot be
logged on.
