Before starting hardware discovery, ensure the following is configured to make the discovery process as smooth as possible.
In order to communicate with IPMI-based hardware (with BMCs), verify that the xCAT
passwd table contains an entry for
ipmi which defines the default username and password to communicate with the IPMI-based servers.
tabdump passwd | grep ipmi
If not configured, use the following command to set
chtab key=ipmi passwd.username=ADMIN passwd.password=admin
The xCAT-genesis packages provides the utility to create the genesis network boot rootimage used by xCAT when doing hardware discovery. It should be installed during the xCAT install and would cause problems if missing.
Verify that the
genesis-base packages are installed:
[RHEL/SLES]:rpm -qa | grep -i genesis
[Ubuntu]:dpkg -l | grep -i genesis
Install them from the
xcat-deprepository using the Operating Specific package manager (
yum, zypper, apt-get, etc)
[RHEL]:yum install xCAT-genesis
[SLES]:zypper install xCAT-genesis
[Ubuntu]:apt-get install xCAT-genesis
Create the network boot rootimage with the following command:
The genesis kernel should be copied to
