Diagnostic commands and scripts

After you enable remote support through SRS, PowerScale Technical Support personnel can request diagnostic commands and scripts that gather cluster data and then upload the data.

Scripts are based on the isi diagnostics gather and isi diagnostics netlogger tools. They are located in the /ifs/data/Isilon_Support/ directory on each node.

NOTE The isi diagnostics gather and isi diagnostics netlogger commands replace the isi_gather_info command.

This tool sends information about a cluster to PowerScale Technical Support.

The following tables list the data-gathering activities that remote support scripts perform. At the request of a PowerScale Technical Support representative, these scripts can be run automatically to collect information about the configuration settings and operations of a cluster. Information is sent to SRS over the secure SRS connection, so that it is available for PowerScale Technical Support personnel to analyze. The remote support scripts do not affect cluster services or data availability.
