SOL not working

David,

Here are my notes about setting up SOL on PE 1955 and PE 2950, showing
what works reliably for us.  The commands below are from OpenManage 5.0
CLI on RHEL4.  If you don't use OM, I'm not sure offhand what the best
alternative query / setting mechanism might be, but hopefully this will
help you anyway.

'omreport chassis remoteaccess' should give:

LAN Enabled: Yes
SOL Enabled: Yes
IP Address Source: Static Address
IP Address: <the unique IP address for this unique BMC>
IP Subnet, IP Gateway as appropriate for given IP Address

'omreport chassis biossetup' should give:

Serial Communications: On with Console Redirection via COM2
Console Redirection After Boot: Enabled
External Serial Connector: Remote Access Device   {not available on
PE1955}
Console Redirection Failsafe BAUD Rate: 57600

I see that on our PE2950s, 'omreport chassis ports' gives info about the
external serial port, saying it's set at 115200 baud.  This makes me
wonder whether the "External Serial Connector" is necessary or not.  The
above settings work at any rate.

For all the above, if you need to change a setting using OM, you use
'omconfig'.

For remote console after the OS is booted, you should have something
like this in /etc/inittab:

co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1 ansi

For both local console and remote console while the kernel is booting,
you should have something like this in your grub kernel options:

console=tty0 console=ttyS1,57600

I believe that when we've had SOL broken, it's usually turned out to be
that 57600 isn't specified in all three places that it's needed.  Other
baud rates will probably work (at least lower ones should), but I can
only vouch for 57600 working on my systems, and you certainly need all
the required settings to be the same value.

Also check that you have 'ttyS1' instead of 'ttyS0'.

Hope this helps, and apologies for continuing the top-posting. ;)
