The diagnostics log file bundle collects the same type of hardware, storage,
and operating system information as is collected when using the Dell System
E-Support Tool (DSET) from the system using the DR4000 system CLI
commands (diagnostics --collect --dset).
The DSET-based information that gets collected for the system can be used
by Dell Support to troubleshoot or evaluate your DR4000 system.

Understanding Diagnostics Collection

The Diagnostics service collection tool process observes the following
guidelines:
• System triggers cause the automatic diagnostic log collection of system
status for any system process or service failures.
• All automatic diagnostic collection requests are queued and executed
sequentially.
• The DR4000 system GUI provides the options to display existing
diagnostics logs, generate new diagnostics logs, download and save
copies of existing diagnostics logs, or delete existing diagnostics logs. For
more information, see "About the Diagnostics Page and Options" on
page 74.
• The DR4000 system CLI also provides the means for managing,
generating, or downloading the diagnostics log files. For more
information, see the
Guide

About the DR4000 Maintenance Mode

In general, the system enters the Maintenance mode whenever the filesystem
has encountered an issue that prevents it from operating normally. When in
its Maintenance mode, the filesystem is in a read-only state, and the system
runs the following maintenance-based operations:
• Runs an internal filesystem check
• Generates a filesystem status report
If the filesystem check finds no issues, the system switches back to
Operational mode without user intervention.
