Chapter 4. Installing and configuring z/VM 45

2. After it is released, you can access the MAINT CF1 disk read-write. Use the LINK

command with the multi-read (MR) parameter and ACCESS command to get read-write

access as your F disk.

==> link * cf1 cf1 mr

==> acc cf1 f

3. Make a backup copy of the vanilla SYSTEM CONFIG file using the COPYFILE command with

the OLDDATE parameter so that the time stamp of the file is not modified. Note that

because the target file name (system) and mode (f) are the same, the equal sign (=) can

be used as a wildcard.

==> copy system config f = conforig = (oldd

4. Edit the original file:

==> x system config f

5. 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

6. 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

7. 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 sets the first three bytes of the MAC address created for each virtual NIC. If

you have 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.
