iocomp command

This command displays the compatibility between all compute nodes and their I/O modules. It can also display detailed interface information for an individual compute node or I/O module.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or iocomp command errors for a list of error messages that are specific to the iocomp command.

Table 1. iocomp command.

The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.

Example: To view I/O module compatibility information for all compute nodes and I/O modules, while CMM 1 is set as the persistent command environment, at the system:mm[1]> prompt, type
iocomp -T system
To view I/O module compatibility information for the compute node in node bay 1, while CMM 1 is set as the persistent command environment, at the system:mm[1]> prompt, type
iocomp -T system:blade[1]
To view I/O module compatibility information for the I/O module in bay 2, while CMM 1 is set as the persistent command environment, at the system:mm[1]> prompt, type
iocomp -T system:switch[2]

The following example shows the information that is returned from these commands:

system:mm[1]> iocomp -T system
