Reset Storage Subsystem Diagnostic Data
This command resets the NVSRAM that contains the diagnostic data for the storage subsystem. This
command does not delete the diagnostic data. This command replaces the Needs Attention status with
the Diagnostic Data Available status. The old diagnostic data is written automatically over when new
data is captured. The memory that contains the diagnostic data is also cleared when the controllers
reboot. Before resetting the diagnostic data, use the
save storageSubsystem diagnosticData command to
save the diagnostic data to a file.
Attention: Run this command only with the assistance of an IBM Technical Support representative.
Syntax
reset storageSubsystem diagnosticData
Parameters
None.
Reset Storage Subsystem iSCSI Baseline
This command resets the iSCI baseline for the storage subsystem to 0.
Syntax
reset storageSubsystem iscsiStatsBaseline
Parameters
None.
Notes
This command resets the baseline to 0 for both controllers in the storage subsystem. The purpose of
resetting both of the controller baselines is to help make sure that the controller counts are synchronized
between the controllers. If one controller resets but the second controller does not reset, the host is
informed that the controllers are out of synchronization. The host is informed by the time stamps that are
reported with the statistics.
Reset Storage Subsystem Logical Drive Distribution
This command reassigns (moves) all of the logical drives to their preferred controller.
Syntax
reset storageSubsystem logicalDriveDistribution
Parameters
None.
Notes
If you use this command on a host without a multi-path driver, to prevent application errors, you must
stop I/O operations to the logical drives until this command has completed.
