Disable EDAC module in CentOS5, IBM BladeCenter

http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?brandind=5000008&lndocid=MIGR-5074651

This is CentOS5:

In /etc/modprobe.conf:
blacklist k8_edac
blacklist edac_mc

Convert DHCP to Static IP for IBM RSA II card

In my case: IBM System x3755 -[7163AC1]

First need to ensure the following in BIOS per IBM:
Enabling USB keyboard and mouse support:

1. Turn on or restart the server and watch the monitor screen.
2. When the message Press F1 for Configuration/Setup appears, press F1.
3. Select Advanced Setup and then select RSA II Settings.
4. In the OS USB Selection field, select Linux.
5. Select Save Values and Reboot RSA II.

Download and Install asu and ibmusbasm64-1.51-2 (custom build RPM from SRPM for Centos5 in my case).

./asu64 show all | grep RSA_DHCP

./asu64 set RSA_DHCP1 Disabled

./asu64 rebootrsa

./asu64 set RSA_HostIPAddress1 new_ip_addr
./asu64 set RSA_HostIPSubnet1 new_subnet
./asu64 set RSA_GatewayIPAddress1 new_gateway_addr

./asu64 rebootrsa

Done.

IBM BladeCenter blade SOL (LS41)

Centos5:

In /etc/inittab:
add one line:
s1:2345:respawn:/sbin/agetty -L -f /etc/issueserial 19200 ttyS1 vt100

root: init q

In /etc/securetty:
add line
ttyS1

In /etc/grub.conf:
add “console=tty0 console=ttyS1,19200″ at the end of kernel line

To access serial console:

console -T system:blade[1]

To exit:
ctrl+[
Then
