Hello,
I have couple Intel SR1550 server platforms and I use IPMI
and SOL on them sucessfully. They all have the same config:
# BIOS settings:
Console Redirection [Serial Port B]
Flow Control [RTS/CTS]
Baud Rate [19.2k]
Terminal Type [VT-100]
Legacy OS Redirection [Enabled]
# sol info
Info: SOL parameter 'Payload Channel (7)' not supported - defaulting to
0x0e
Info: SOL parameter 'Payload Port (8)' not supported - defaulting to 623
Set in progress : set-complete
Enabled : true
Force Encryption : true
Force Authentication : true
Privilege Level : ADMINISTRATOR
Character Accumulate Level (ms) : 20
Character Send Threshold : 50
Retry Count : 6
Retry Interval (ms) : 20
Volatile Bit Rate (kbps) : IPMI-Over-Serial-Setting
Non-Volatile Bit Rate (kbps) : 19.2
Payload Channel : 14 (0x0e)
Payload Port : 623
# grub.conf
[...]
module /boot/vmlinuz-2.6.18-128.1.10.el5xen ro root=LABEL=/ [...]
xencons=ttyS1 console=tty console=ttyS1,19200n8
[...]
So to sum up; I get whole BIOS POST (serial port B) and
system boot messages (ttyS1 - COM2) on serial-over-lan
console with no problems.
Lately I've bought new Intel platform - SR1625.
This is Nehalem arch with S5520 board.
So I've tried to configure IPMI and SOL the same way
as above but the problem was I've been getting through
SOL only BIOS POST messages. Once grub has been taking
control over the boot process - SOL has been freezing.
After many hours of tests I've figured out that if I change
kernel Grub configuration from ttyS1 to ttyS0, then I see
also OS boot messages.
So my question is why/how come does it work in such
configuration (bios: serial B, system: ttyS0)
and what shell I do if I'd like to change it to ttyS1
as on other machines and see boot messages again.
TIA.
PS. The only difference in SOL configuraction is:
Payload Channel : 14
which seems to be default in BMC of Intel SR1550.
On new Intel SR1625 I get::
Payload Channel : 1 (0x01)
with no additional default channel errors.
