modules [optional-module-name]
Without this entry, all of the module names are displayed. Each module name will also have its debug
level displayed, along with the debug level for any types that are different. The rest of the available
type data will be included within parentheses on the display line. See “Set debug command” on page
50 for information on setting debug levels.
sac [sac-command]
Command that is sent to the sac in order to extract sac data. Show debug sac will return a list of
available sac commands. Show debug sac status returns the status of the sac.
Notes
As this command returns a large amount of information to the screen, turn on logging in your terminal
program so that you can capture all the information in a file to send to HP.
Examples
show debug modules cssdev will return a line that looks like:
cssdev=err (ucmd) which indicates that the kernel module cssdev has a debug level set
to err. There is one extra type ucmd that can have different debug level set in cssdev. Show
debug sac initiators will display initiator information from the sac.
