Command Line Reference Guide .
The DSET-based information that gets collected for the system helps Dell Support to troubleshoot or evaluate the status
of your DR Series system.
Understanding Diagnostics Collection
The Diagnostics service collection tool process observes the following guidelines:
• DR Series system triggers an automatic diagnostic log collection of the DR Series system status for any system
process or service failures.
• All automatic diagnostic collection requests are queued and executed sequentially.
• The DR Series system GUI provides 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
Diagnostics Page and Options and About the Diagnostics Service.
• The DR Series system CLI also provides the means for managing, generating, or downloading the diagnostics log
files. For more information, see the Dell DR Series System Command Line Reference Guide .
About the DR Series System Maintenance Mode
In general, the DR Series system enters the Maintenance mode whenever the file system has encountered an issue that
prevents it from operating normally.
NOTE: You can use the Reason code information available in the Maintenance mode to call Dell Support. All
maintenance must be conducted using the DR Series systems Command Line Interface.
When in its Maintenance mode, the filesystem is in a read-only state, and the system runs the following maintenance-
based operations:
NOTE: Whenever the DR Series systems enters or exits from the Maintenance mode state, all communication via
protocols is lost.
• Runs an internal filesystem check.
• Generates a filesystem status report (if the filesystem check finds no issues, the DR Series system switches back to
Operational mode without user intervention).
If the filesystem check finds issues, you can choose to make repairs (using Confirm Repair Filesystem) or ignore the
detected issue (using Skip Repair Filesystem), at which point the system switches back to Operational mode.
The Maintenance mode process displays a number of stages, indicated on the Maintenance Mode progress bar, which
include:
• Preparing for Filesystem Check
• Scan in Progress
• Completed Generating Report
NOTE: If the Filesystem Check detects any repairable files, it generates a Repair Report that identifies these
reported files. The Maintenance Mode progress bar halts at the Completed Generating Repair stage, and
remains in Maintenance mode until you click Confirm Repair Filesystem. The DR Series system does not
advance to the Switching to Operation Mode stage until the filesystem repair is completed.
• Switching to Operational Mode
• Operational Mode (Normal State)
