Establishing a SOL session
Prerequisite:
This
procedure
assumes
that
the
required
setup
for
IPMI
‐
over
‐
LAN
has
been
done
once
for
this
CPM.
For
details,
see
Configuring
IPMI
‐
over
‐
LAN
access
on
page 63.
One-time SOL configuration steps
The
following
two
steps
configure
the
CPM
for
SOL:
1. In
the
CPM
BIOS
Setup,
change
the
active
serial
port
to
COM1,
as
follows:
Advanced
Settings
>
Serial
Port
1
Configuration
>
Serial
port:
Enabled
2. Set
the
Linux
console
parameters
to
COM1
(ttyS1)
to
support
SOL.
To
configure
retry
settings
from
a
remote
computer:
Important:
For
these
one
‐
time
steps,
use
the
Radisys
‐
supplied
rsys
‐
ipmitool
utility.
3. Configure
the
retries
to
keep
SOL
sessions
open
for
a
Base
interface
IP
address.
rsys
‐
ipmitool
‐
I
<protocol>
‐
H
<IP>
‐
A
none
‐
C
0
sol
set
retry
‐
interval
0xF0
rsys
‐
ipmitool
‐
I
<protocol>
‐
H
<IP>
‐
A
none
‐
C
0
sol
set
retry
‐
count
7
For
an
explanation
of
<protocol>
and
<IP>
,
see
Before
you
begin
on
page 63.
4. Repeat
Step
to
configure
retries
for
the
other
Base
interface
IP
address.
5. View
the
retry
settings
for
a
Base
interface
IP
address.
rsys
‐
ipmitool
‐
I
<protocol>
‐
H
<IP>
‐
A
none
‐
C
0
sol
info
The
retry
count
should
be
7,
and
the
retry
interval
should
be
2400
ms.
6. Repeat
Step 5
to
verify
access
to
the
remaining
interface
IP
addresses.
7. The
SOL
payload
is
disabled
by
default.
Enter
the
following
command
to
enable
it:
rsys
‐
ipmitool
‐
I
lanplus
‐
H
<IP>
‐
A
none
‐
C
0
sol
payload
enable
Note:
For
proper
SOL
operation
during
BIOS
POST
and
at
OS
runtime,
the
BIOS
console,
OS
console,
and
SOL
baud
rates
must
all
agree.
The
default
SOL
parameters
include
a
38400
baud
rate
instead
of
the
default
BIOS
console
redirection
baud
rate
of
115200.
The
38400
baud
rate
might
be
better
at
avoiding
character
drops
during
a
SOL
session.
8. Both
the
volatile
and
non
‐
volatile
bit
rates
must
be
set
to
the
same
value.
Enter
the
following
commands
to
set
the
baud
rate
to
115200:
rsys
‐
ipmitool
‐
I
lanplus
‐
H
<IP>
‐
A
none
‐
C
0
sol
set
non
‐
volatile
‐
bit
‐
rate
115.2
rsys
‐
ipmitool
‐
I
lanplus
‐
H
<IP>
‐
A
none
‐
C
