The Virtualization Cookbook for SLES 10 SP2 - z/VM - IBM

==> copy system config f = conforig = (oldd
► Edit the original file:
==> x system config f
► The system name is set to ZVMV6R10 by default in the System_Identifier_Default
statement. You can search for it using the / subcommand:
====> /System_Identifier_D
Modify this to the new name of your system. In this example POKSND61 is used.
System_Identifier_Default POKSND61
► Next look for the Features statement. You can search for it again or you can use F8 to
page down. The following changes and additions are recommended:
– Increase the number of commands that can be retrieved from 20 to 99.
– Set the Disconnect_Timeout to off so disconnected users do not get forced off.
– Allow unlimited VDISKs to be created by users by changing Userlim to infinite and
by adding the Syslim infinite clause:
Features ,
Disable , /* Disable the following features */
Set_Privclass , /* Disallow SET PRIVCLASS command */
Auto_Warm_IPL , /* Prompt at IPL always */
Clear_TDisk , /* Don't clear TDisks at IPL time */
Retrieve , /* Retrieve options */
Default 99 , /* Default.... default is 20 */
Maximum 255 , /* Maximum.... default is 255 */
MaxUsers noLimit , /* No limit on number of users */
Passwords_on_Cmds , /* What commands allow passwords? */
Autolog yes , /* ... AUTOLOG does */
Link yes , /* ... LINK does */
Logon yes , /* ... and LOGON does, too */
Disconnect_Timeout off , /* Don't force disconnected users */
Vdisk , /* Allow VDISKS for Linux swaps */
Syslim infinite ,
Userlim infinite
► Define a VSWITCH:
Use the BOTTOM subcommand to go to the bottom of the file. Add some lines (you can use
the XEDIT add subcommand a3). Define a VSWITCH and set the MAC address prefix. This
will set the first three bytes of the MAC address created for each virtual NIC. If you have a
multiple z/VM systems, increment this value to avoid having identical MAC addresses
created. The last three bytes of the MAC address are automatically incremented by z/VM
as they are assigned, so they will be unique on each z/VM system. Modify the two starting
addresses of the OSA triplets (B440 and B424 in this example) to those you specified in
2.7.1, “z/VM resources worksheet” on page 16.
====> bot
====> a3
/* define vswitch named vsw1 and set MAC address prefixes to 02-00-01 */
define vswitch vsw1 rdev B440 B424
vmlan macprefix 020001
► Save your changes with the XEDIT FILE subcommand:
====> file
► Test your changes with the CPSYNTAX command which is on the MAINT 193 disk:
==> acc 193 g
==> cpsyntax system config f
