To diagnose problems, it is helpful to understand the relationship between
CSM and the tools that it uses. These tools are described in the
following table:
Tool | What It Does | CSM Interface |
---|---|---|
Resource Monitoring and Control (RMC) subsystem | Monitors conditions and communicates with all nodes. RMC needs to be running on each node, and the security access control list (ACL) file needs to allow the nodes to communicate with the management server. See Providing security. | CSM and ERRM commands |
dsh | Runs commands remotely on the nodes. Security needs to be set up on each node to allow this for the remote shell that is used by dsh. The default remote shell is rsh. | The CSM csmsetupks and updatenodecommands |
syslinux | Enables network booting during installation. | The CSM csmsetupks, getmacs, and installnode commands |
atftp | Advanced tftp. Handles file transfers during installation. | The CSM csmsetupks, getmacs, and installnode commands |
The following tips can help you diagnose problems with a CSM cluster:
lsnode -l
lssrc -a
lsaudrec
dsh -a date
