You should now have three new parameter files and three new configuration files.
9.5.3 Adding new virtual machines to the startup process
Modify the PROFILE EXEC file on AUTOLOG1 191 to grant access to the VSWITCH for the
three new user IDs and add XAUTOLOG commands so they boot when you perform an IPL
of z/VM system.
Perform the following steps:
1. Link and access the AUTOLOG1 191 disk so the file can be modified from MAINT:
==> link autolog1 191 1191 mr
==> acc 1191 f
Edit the PROFILE EXEC file and add three new SET VSWITCH commands and three new
XAUTOLOG commands:
==> x profile exec f
...
/* Grant access to VSWITCH for each Linux user */
'cp set vswitch vsw1 grant rh6clone'
'cp set vswitch vsw1 grant rh6gold'
'cp set vswitch vsw1 grant rh6gold2'
'cp set vswitch vsw1 grant linux01'
'cp set vswitch vsw1 grant linux02'
'cp set vswitch vsw1 grant linux03'
'cp set vswitch vsw1 grant linux04'
/* XAUTOLOG each Linux user that should be started */
'cp xautolog rh6clone'
'cp xautolog linux01'
'cp xautolog linux02'
'cp xautolog linux03'
'cp xautolog linux04'
'cp logoff' /* logoff when done */
