48 z/VM and Linux on IBM System z: The Virtualization Cookbook for Red Hat Enterprise Linux 6.0
7. Save your changes with the FILE subcommand:
====> file
8. Log off of AUTOLOG1:
==> log
When you perform an IPL of your z/VM system, the TCP/IP stack should now come up
automatically (as long as you do
not specify the notautolog parameter at IPL time).
4.5.1 Renaming the TCPIP configuration file
We recommend that you change the name of the main TCPIP configuration file from PROFILE
TCPIP to <system_ID> TCPIP, where <system_ID> is the name of your new z/VM system. This
is to avoid the possibility that the PROFILE TCPIP file will be overwritten when applying
maintenance.
Perform the following steps:
1. Log on to TCPMAINT. The PROFILE TCPIP file is on the TCPMAINT 198 disk, which is
accessed as the D disk.
2. Make a backup copy of the original PROFILE TCPIP file, then rename it to <SYSTEM_ID>
TCPIP (where <SYSTEM_ID> is POKSND61 in this example). When the TCPIP service machine
starts, it will search for this file before the PROFILE TCPIP file.
==> copy profile tcpip d = tcpiorig = (oldd
==> rename profile tcpip d poksnd61 = =
3. You have now backed up and renamed your TCP/IP profile. You can verify this using the
LISTFILE command:
==> listfile * * d
POKSND61 TCPIP D1
PROFILE $TCPBAK D1
SYSTEM $DTCBAK D1
SYSTEM DTCPARMS D1
TCPIORIG PROFILE D1
4.5.2 Copying the PROFILE XEDIT file
Again, copy the PROFILE XEDIT file from the MAINT 191 disk so that XEDIT sessions will have
a common interface among user IDs.
Perform the following steps:
1. Use the VMLINK command to both link to the disk read-only and to access it as the
highest available file mode. The default read password is read:
==> vmlink maint 191
ENTER READ PASSWORD:
read
DMSVML2060I MAINT 191 linked as 0120 file mode Z
2. Copy the PROFILE XEDIT file to your A disk:
==> copy profile xedit z = = a
Now, XEDIT sessions on TCPMAINT will have the same configuration as on MAINT.
