Chapter 8. Frequently Asked Questions
Q: Does the SCON support NIP consoles?
A: Yes. You can define NIP and MCS (MVS) consoles to the SCON. It is good
planning to define multiple NIP consoles, spread across more than one SCON
for redundancy sake.
Q: Can you change the configuration of one LPAR on the SCON, or add a new
LPAR definition without performing an IML?
A: No, you can not. That is why it is important to have a redundant SCON, with
alternate consoles defined to it. By having redundant SCONs, you can take one
down for periodic maintenance while the other SCON is providing critical
services.
Q: Will a Telnet or TN3270E client get a live console session when they connect in?
A: Only if the Hot Session option is configured on the SCON. Otherwise, if the
client is not connected when the LPAR first comes up, the device is reported as
being powered off, and the console session would role to the alternate console
or to the support element.
Q: How does the Hot Console Session feature work?
A: The SCON treats a Hot Console Session as if the device were always powered
up. Console messages are received and discarded by the SCON when no client
is connected to the session. When a client does connect to the session, a clear is
sent inbound automatically to cause the host to repaint the latest screen.
Q: Can a console operator retrieve messages discarded by the SCON from a Hot
Session?
A: No, not directly from the SCON. You would need to access the SDSF, on the host.
Q: Can I configure a combination of regular console session and Hot Console
sessions?
A: Yes. You can determine which sessions need to be hot and which ones do not.
Q: Can I configure Hot VTAM sessions?
A: In general, you do not need to. The host should detect when a VTAM terminal
powers up, and provide the user with a session. The hot session feature of the
SCON was designed specifically for use with consoles. Configuring a VTAM
session as a hot session may result in unpredictable results.
Q: How do I make a Hot Session roll to another terminal?
A: Do not configure a Hot Session if you need it to roll to another terminal
automatically. If you need to switch control of a console to another device use
the procedure described in Chapter 7 under ‘Activating Consoles’.
Q: Is there any way around having to configure the device candidate list in
my GEN?
A: Yes. By configuring the Channel Path Filtering option to the SCON, it is possible
to configure around the device candidate lists in HCD.
Q: Is it possible to share a console session between two or more operators?
A: Yes. You can share a single session between up to 24 people at one time (if the
session is configured to be shared). All operators may enter console commands,
and each of the operators sharing the session will see the results of the command
entered. This option can be used for training, joint problem determination, and
disaster recovery situations.
