If Linux does not boot, verify that all the disks were successfully copied.
Now Linux is running on S10RWTST - the system on which maintenance is designed to be
done. The following configuration changes are recommended. Of course you may add or
delete steps, however certain steps such as adding the cmsfs package, loading the vmcp
module, and copying boot.findself are required for this solution to work:
򐂰 The parameter line and menu delay are changed in /etc/zipl.conf.
򐂰 The CMS file system (cmsfs) package is installed.
򐂰 The cmm and vmcp modules are set to be loaded at boot time.
򐂰 The system is set to halt, not reboot, when z/VM is shut down, and the default run level is
set to 3.
򐂰 The script boot.findself is copied for newly cloned systems to find their IP and DNS
information.
򐂰 Empty mount points are created under /opt/ for the possibility of mounting middleware
򐂰 The script cloneprep.sh is copied to aid in cleanup before cloning.
Modifying zipl.conf
The parameter line is modified in /etc/zipl.conf in three ways:
򐂰 The menu time-out (timeout) is reduced from 10 seconds to 3 so Linux IPLs more quickly
with no user input.
򐂰 The dasd= parameter is added so there are well-known “slots” for additional disks at
addresses 1B9-1BF (i.e. /dev/dasdi - /dev/dasdp), 2B0-2BF and 320-33F. The additional
slots from 1B9-1BF can be used for adding devices for file systems (e.g. adding a minidisk
