Subject: [LINUX-390] SYSASCII console use for Linux
I found this statement in the Linux-390 archives from Rick Troth and was
wondering if any one has used this interface or if there are more details on
using it
*Linux sees an ASCII "system console"*
This is where I had to do a little digging. They don't let me on the HMC
so I have never gotten access to the SYSASCII interface. Sounds like a
great idea. IBM realizes that some mainframe operating systems are
better served with a byte-at-a-time interface. (Call it "ASCII", but the
significant feature is not the character set. Character sets are so 1980.)
z/VM can attach a SYSASCII to a Linux guest. Linux can then use the
SYSASCII console interface and a non-mainframe Linux person would be
perfectly comfortable.
We need a way to give our Linux admins real terminal access to an ASCII
terminal for Boot Messages and to fix issues that prevent Network access.
The Linux Admins do use an HMC access method for the AIX systems they support
and want to use the same thing for z/VM Linux servers
1. Is this possible if the HMC has access to the z/VM LPAR
2. Are there specific Steps to activate the SYSASCII console when attached
to Linux
* Even if I attach SYSASCII to a Linux server it is not actually active
q sysascii
SYSASCII attached to GLTRHEL8 inactive
* How to I get SYSACSII activated
