BXadmin:Configure IPMI SOL

Note: This was written with the Dell BMCs in mind, but should loosely apply to other IPMI SOL implementations.

Configure console redirection by going into Serial Communication in the BIOS:

Note: Set the Failsafe Baud Rate to 57600! Other speeds may or may not work!

In the Remote Access BIOS, enable IPMI over LAN and set NIC selection to shared.

The rest of the network/user settings can either be configured via the Remote Access BIOS screen, or via the OS.

On linux, modprobe ipmi_devintf and ipmi_si

ipmitool -I open lan set 1 ipsrc static
ipmitool -I open lan set 1 ipaddr <ip address>
ipmitool -I open lan set 1 netmask <netmask>
ipmitool -I open lan set 1 defgw ipaddr <ip address>
ipmitool -I open lan set 1 vlan id 1
ipmitool -I open lan set 1 access on

ipmitool user set name 2 admin
ipmitool -I open user set password 2
ipmitool channel setaccess 1 2 callin=on ipmi=on link=on privilege=4
ipmitool user enable 2

Run ipmitool -I open lan print to see if VLANs are supported.

Enable GRUB and the kernel to output to serial.

In /boot/grub/menu.lst:

serial --unit=1 --speed=57600
terminal --timeout=5 serial console

Then append to the kernel line:

console=tty0 console=ttyS1,57600n8

Finally, edit /etc/inittab to get a login prompt on ttyS1:

co:2345:respawn:/sbin/agetty ttyS1 57600 vt100-nav

Solaris on Dell R715

The BMC on the R715 seems to default to 115200 when the BIOS is not controlling it. The 'failsafe' setting in the BIOS seems to be only for BIOS output. After that, the baud rate jumps back up to 115200.

In any case, "Console redication via COM2" and "Redirect After Boot = Enabled" need to be set in the BIOS. Failsafe baud rate can mostly be anything, though something between 9600 and 57600 seems to be the safest with SOL. Also, comment out the splashimage line in /rpool/boot/grub/menu.lst so you can interact with GRUB via console.

The pmadm and sacadm commands came from http://pbraun.nethence.com/doc/sysutils_solaris/solaris.html

console=text, zsmon for serial login prompt

$ eeprom console=text
$ pmadm -r -p zsmon -s ttyb
$ pmadm -a -p zsmon -s ttyb -i root -v `ttyadm -V` -m "`ttyadm -i 'Terminal disabled' -l 115200 -m ldterm,ttcompat -S y -d /dev/ttyb -s /usr/bin/login -T vt100`" -f u

Then restart zsmon if you don't want to reboot:

$ sacadm -k -p zsmon
$ sacadm -s -p zsmon

Then edit /etc/default/login and comment out "CONSOLE=/dev/console" to allow root to login via the /usr/bin/login prompt on ttyb.

console=ttyb, no physical console login

$ pmadm -r -p zsmon -s ttyb # make sure we don't have anything fighting for access for ttyb
$ eeprom console=ttyb
$ eeprom ttyb-mode="115200,8,n,1,-"
$ svccfg -s console-login setprop ttymon/label=115200

Alternatively, instead of setting ttymon/label, you can change the definition for console in /etc/ttydefs

Alternatively alternatively, you can set ttymon/device to /dev/ttyb and ttymon/terminal_type to vt100
