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.

vCenter Converter 4.0 Sysprep warning

When trying to convert Windows2k3 Standard server using VMware vCenter Converter, I got following warning message:

Warning: Unable to locate the required Sysprep files. Please upload them under ‘c:\Documents and Settings\All Users\Application Data\VMware\VMware vCenter Converter Standalone\sysprep\svr2003′ on the Converter server machine.

Go to CD1, Win2003-R2-i386std-cd1\SUPPORT\TOOLS, copy and extract DEPLOY.CAB to the above mentioned folder, then restart vCenter Converter session, the warning will go away ..

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
ctrl+(

DB2 “does not have the authority to perform the requested command”

It turns out user used “chown -R instanceUsername:anotherGroupname sqllib”, thus changed lots of permissions.

Tried to reset permission using “/opt/IBM/db2/V9.5/instance/db2iupdt -k instanceUsername”, but still not working after that.

The workaround, per IBM, is to:

1. Uncatalog database;
2. Drop instance;
3. Create instance;
4. Catalog database again;

so as instance owner (note: I got the same error: instance owner does not have authority .. This step can be skipped .. ):
db2 uncatalog database db1
db2 uncatalog database db2

as root:
/opt/IBM/db2/V9.5/instance/db2idrop instanceUsername

/opt/IBM/db2/V9.5/instance/db2icrt -u db2fenc1 instanceUsername

as instance owner:
db2 catalog database db1 as db1
db2 catalog database db2 as db2
db2 terminate

Apache frontend Tomcat

For Apache to be front end of Tomcat:

Say appname is at http://servername:8080/appname

1.
Redirect / http://servername/appname/
ProxyPass /appname/ http://localhost:8080/appname/
ProxyPassReverse /appname/ http://localhost:8080/appname/

2.
LoadModule jk_module modules/mod_jk.so
JkWorkersFile /etc/httpd/conf/workers.properties
JkShmFile /var/log/httpd/mod_jk.shm
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat “[%a %b %d %H:%M:%S %Y]“

$ cat /etc/httpd/conf/workers.properties
# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

(virtual host config)
RewriteEngine on
Rewriterule ^/$ /appname/ [R=301]
JkMount /appname/ worker1
JkMount /appname/* worker1

3. conf.d/proxy_ajp.conf:
uncomment:
ProxyPass /appname/ ajp://localhost:8009/appname/

pxeboot / kickstart

This is for Pxeboot / Kickstart a Rackable server. The first NIC cable is loose, and DHCP is configured to go to 2nd NIC. But kickstart is configured as:
network –bootproto dhcp

which trying to use eth0 all the time, and of course failed all the time.

The fix is to add “ksdevice=bootif” in the line “append” in pxeboot menu, and add “IPAPPEND 2″ line below.

It would show 2 devices to be manually picked in this case, after picking the 2nd NIC, it is working again.
