z/VM USER DIRECTORY CREATION PROGRAM - VERSION 5 RELEASE 3.0
EOJ DIRECTORY UPDATED AND ON LINE
You have now defined the user ID that will be the master Linux image.
8.1.2 Adding RHEL52 to the AUTOLOG1 PROFILE EXEC
The new Linux ID you defined needs access to the VSWITCH. Just as with the LNXINST user,
a SET VSWITCH command with the GRANT parameter will now be added to the AUTOLOG1 PROFILE
EXEC. Also, an XAUTOLOG statement is added so that the RHEL52 user ID is automatically logged
on at z/VM IPL time.
Link and access the AUTOLOG1 191 disk as read/write and edit the file PROFILE EXEC. Add the
RHEL52 user ID to the section that grants access to the VSWITCH. Do not add RHEL52 to the
XAUTOLOG section, because this Linux user ID will not normally be logged on:
==> link autolog1 191 1191 mr
==> acc 1191 f
==> x profile exec f // add two lines
/***************************/
/* Autolog1 Profile Exec */
/***************************/
'cp xautolog tcpip' /* start up TCPIP */
'CP XAUTOLOG DTCVSW1' /* start VSWITCH controller 1 */
'CP XAUTOLOG DTCVSW2' /* start VSWITCH controller 2 */
'cp set pf12 ret' /* set the retrieve key */
'cp set mdc stor 0m 128m' /* Limit minidisk cache in CSTOR */
'cp set mdc xstore 0m 0m' /* Disable minidisk cache in XSTOR */
'cp set srm storbuf 300% 250% 200%' /* Overcommit memory */
'cp set signal shutdown 300' /* Allow guests 5 min to shut down */
/* Grant access to VSWITCH for each Linux user */
'cp set vswitch vsw1 grant lnxinst'
'cp set vswitch vsw1 grant rhel52'
/* XAUTOLOG each Linux user that should be started */
'cp xautolog lnxinst'
'cp logoff' /* logoff when done */
====> file
These changes will not take effect until the next IPL, so you must grant this user ID access to
the VSWITCH for this z/VM session:
==> set vswitch vsw1 grant rhel52
