Dell PowerVault MD3420 - Manual (Page 366)

Parameters
None.
Notes
Upon completion of the diagnostic test, the RAID controller module firmware returns one of these
results:
• Diagnosis completed without errors. No ZIP file created.
• Diagnosis completed with errors. Refer to the ZIP file created at:
...\Install_dir\data\FirmwareUpgradeReports\timestamp_buildNo.zip
If the diagnostic test detects an inconsistency in the configuration database, the RAID controller module
firmware performs these actions:
• Returns a description of the inconsistency.
• Saves a ZIP file containing raw binary data.
The RAID controller module firmware saves the ZIP file to this location:
...\Install_dir\data\FirmwareUpgradeReports\timestamp_buildNo.zip
The binary data can be used to help determine the cause of the problem, or the file containing the binary
data can be sent to a Customer and Technical Support representative.
To stop the database configuration diagnostic test, use the stop storageArray
configDbDiagnostic command.
In addition, the database configuration diagnostic test can be started using the storage management
software GUI but cannot be stopped using the storage management software GUI. If you want to stop a
running diagnostic test, you must use the stop storageArray configDbDiagnostic command.
Start Consistency Group Snapshot Rollback
Description
This command starts a rollback operation to the member base virtual disks in a snapshot consistency
group. The content of the base virtual disks changes immediately to match the point-in-time content of
the consistency group snapshot virtual disk. The base virtual disks immediately becomes available for
read/write requests after the rollback operation has successfully completed. To stop a snapshot
consistency group rollback operation, use the stop rollback command for consistency groups.
The repository virtual disk that is associated with the consistency group snapshot virtual disk continues to
track any new changes between the base virtual disk and the consistency group snapshot virtual disk that
occur after the rollback operation is completed.
To stop a rollback operation to the member base virtual disks use the stop cgSnapImage rollback
command.
Syntax
start cgSnapImage ["consistencyGroupName"] rollback
[memberVirtualDiskSet ["memberVirtualDiskName1 ... memberVirtualDiskNamen"]]
