Amen to that. VM TCP/IP doesn't get any more of a free pass than any
other guest and gets all the benefits VSWITCH can provide.
The only question you need to be able to answer is: What is your alternate
logon path if VM TCP/IP OR the VSWITCH is down? You need to have
emergency automation, OSA-ICC or HMC 3270.
WARNING: THE OSAs ARE NOW IN THE POSESSION OF VM TCP/IP
ONLY TELNET IS AVAILABLE. ACCESS IS RESTRICTED TO
MAINT, OPERATOR, AND SUPER-SECRET USERID CHUCKIE.
YOU HAVE -- 15 -- MINUTES UNTIL SYSTEM SHUTDOWN.
