System information

Sharing and maintaining SLES 10 SP2 Linux under z/VM 41
3. Grant the new user ID access to the VSWITCH. The following statement is put in
AUTOLOG1’s PROFILE EXEC:
'cp set vswitch vsw1 grant lnx226'
This command is also run interactively from the command line for the current z/VM session.
By using the SLES 10 SP2 parameter file to maintain the IP address and host name, there is
a side effect. If for some reason you need to install Linux manually, or even use the install
process as a rescue system, this file will be available and the same IP/DNS information will
be used.
The read-write Linux system is cloned to the LINUX226 user ID via the CLONERW EXEC:
==> clonerw lnx226
Checking that source and target user IDs are logged off

You should now have four identical systems, three of which can be IPLed: S10RWMNT,
S10RWTST and LNX226. All of these have identical IP and DNS information. For the first three
system user IDs, this is acceptable knowing that only one will be booted at a time. However,
the target systems will naturally need unique IP and DNS host name values. This is
accomplished at first boot time by the boot.findself script.
