10 Troubleshooting
Detecting new hardware
NOTE: This section applies only to the image version of Cluster Test.
When Cluster Test is installed on a head node of a new, unsupported model, or when Cluster Test is booted on a compute node on a new, unsupported model, a menu will be displayed with options for you to choose from. The message will look similar to
Model DL370G10 is not supported
Your options are:
1)Gather information about this model to send to the ClusterTest team.
2)Assume this model is like another, supported model and continue
Option 1: Cluster Test gathers information about the model, and if possible, saves it to the install media (this works for USB and network installs, but will not work for DVD installs). Information about the system is written to a tar file that is copied to the install media. Assuming everything goes well, your install media (your USB drive for USB installs, the capture directory for network installs, or the network install directory if no capture directory was specified) will contain a tar file similar to
Send the tar file to the Cluster Test team at
Option 2: You will be prompted for a supported model to use instead.
These are the models supported by ClusterTest:
DL360G4 DL360G5 DL360G6
What model do you want to assume to boot this DL360G7 (enter q for quit)?
Cluster Test will attempt to complete the installation by assuming your DL360G7 is the model you specify. This might not work. If the installation is successful, an entry will be made to /opt/ clustertest/model_info on the head node, that describes the new model. This description will be used by clsetup.pl and other commands run from the head node.
Once you have successfully installed the head node using this approach, you may update the /tftpboot/netboot_initrd.gz file, which is used to boot the compute nodes, by running the apply_new_model_updates command. This command updates the /tftpboot/ netboot_init.gz with the collected information and should be run before booting any of the compute nodes.
