Setting the Available Spare Threshold

About this task

The Set Available Spare Threshold is supported on PCIe SSDs and PERC. The Set Available Spare Threshold option provides added feature functionality to configure the threshold limit for the Available Spare NVMe PCIe SSDs.
NOTE: The available spare threshold does not support on SSDs connected to an HBA controller.
NOTE: The available spare threshold can be set on PCIe SSDs connected to BOSS-N1 controller, software RAID controllers, PERC controllers, and PCIe SSD sub systems.

To set the Available Spare Threshold:

Steps

  1. In the Server Administrator window, under the System tree, select the Storage tree object.
    The storage Properties window is displayed.
  2. Click the Health subtab to display more information.
  3. Click the Set Available Spare Threshold link available on the Storage Dashboard to access this operation.
    NOTE: The default warning threshold value is set at 10%, and the default critical threshold value is set at 5%.
    NOTE: If the warning threshold value for an available spare is set, a warning alert message is generated when it reaches the value or less than that. If the critical threshold for an available spare is set, a critical alert message is generated when it reaches the value or less than that.
    NOTE:  You can select this option from the Information/Configuration tab > Global Tasks also.
    The Set Available Spare Threshold window is displayed.
  4. In Set Threshold for PCIe SSD (1-99), enter the appropriate threshold value.
    NOTE: If available spare threshold value is set an alert message is generated.
    NOTE: The threshold value cannot be set to 100%.
  5. Click Apply Changes.
    NOTE: If you click Apply Changes without entering a new threshold value for either of the available options an error message is displayed. Enter a new threshold value and then click Apply Changes to successfully complete the task.
  6. After you click Apply Changes, Storage Management updates the system with the new threshold values. After the task is completed, you will be redirected to the Information/Configuration window.
    NOTE:  The newly entered threshold values are retained even after you upgrade Server Administrator.
    NOTE:  When the Available Spare of the SSD drops below the configured threshold, an alert is logged and based on the ‘alert type selection’ the SNMP trap is received for the same. For more information about SNMP traps, see the Dell OpenManage SNMP Reference Guide at openmanage manuals. The threshold polling interval is scheduled to repeat every five minutes. For more information about the polling interval, see the SMART attribute polling interval.
