Configuring SSD Wear Threshold alert features using web interface
To configure Remaining Rated Write Endurance and Available Spare Alert Threshold using web interface:
1. In the iDRAC Web interface, go to Configuration > System Settings > Hardware Settings > SSD Wear Thresholds.
The SSD Wear Thresholds page is displayed.
2. Remaining Rated Write Endurance You can set the value between 1-99%. The default value is 10%.
Alert type for this feature is SSD Wear Write Endurance and security alert is Warning as a result of threshold event..
3. Available Spare Alert Threshold You can set the value between 1-99%. The default value is 10%.
Alert type for this feature is SSD Wear Available Spare and security alert is Warning as a result of threshold event.
Configuring SSD Wear Threshold alert features using RACADM
To configure Remaining Rated Write Endurance, use the command:
racadm set System.Storage.RemainingRatedWriteEnduranceAlertThreshold n
, where n= 1 to 99%.
To configure Available Spare Alert Threshold, use the command:
racadm System.Storage.AvailableSpareAlertThreshold n
, where n= 1 to 99%.
Configuring persistence policy settings
Using IO identity, you can configure policies specifying the system reset and power cycle behaviors that determine the
persistence or clearance of the virtual address, initiator, and storage target settings. Each individual persistence policy attribute
applies to all ports and partitions of all applicable devices in the system. The device behavior changes between auxiliary powered
devices and non-auxiliary powered devices.
NOTE:
The Persistence Policy feature may not work when set to default, if the VirtualAddressManagement attribute
is set to FlexAddress (not for MX platforms) or RemoteAssignedAddress (for MX platforms) mode on iDRAC and if
the FlexAddress or Remote-Assigned Address feature is disabled in CMC (not for MX platforms) or OME Modular (for
MX platforms), ensure that you set the VirtualAddressManagement attribute to Console mode in iDRAC or enable the
FlexAddress or Remote-Assigned Address feature in CMC or OME Modular.
You can configure the following persistence policies:
Virtual Address: Auxiliary powered devices
Virtual Address: Non-Auxiliary powered devices
Initiator
Storage target
Before applying the persistence policy, make sure to:
Inventory the network hardware at least once, that is, enabled Collect System Inventory On Restart.
Enable I/O Identity Optimization.
Events are logged to the Lifecycle Controller log when:
I/O Identity Optimization is enabled or disabled.
Persistence policy is changed.
Virtual address, initiator and target values are set based on the policy. A single log entry is logged for the configured devices
and the values that are set for those devices when the policy is applied.
Event actions are enabled for SNMP, email, or WS-eventing notifications. Logs are also included in the remote syslogs.
