ONTAP 9
Spare Low

Description

When a node's RAID group(s) does not have an eligible spare disk drive available in case of a disk drive failure, ONTAP will report:

(SPARES_LOW) ERROR - AutoSupport message

Which can lead to an Automatic shutdown if not corrected:

Procedure

Follow this guide to help you locate the proper solution to your question or issue.

	Solution
Overview	How low spare warnings can help you manage your spare disks Commands for managing disks Can an ONTAP High Availability Pair be covered by a single "global" spare drive? What does "callhome.spares.low" mean How does ONTAP Trigger Spares Low Check What sparing criteria does the 'Low number of spare disks' healthcheck use? How to disable SPARES_LOW AutoSupport notifications
Advanced Disk Partitioning (ADP)	SPARES_LOW ERROR messages when using ADP Disk failure causing partner node to have SPARES_LOW alert SPARES_LOW reported in active-passive and ADP configuration Spare disks get auto-partitioned when not needed Spares low warning with all partitions of a disk available
Assignment	Correct misaligned spare partitions Call home for SPARES_LOW due to unassigned drives Weekly (SPARES_LOW) ERROR in a mix of partition and unpartitoned disks
Drive failure	Spare disk failed Disk failed, whole spare was auto-partitioned which caused SPARES_LOW alert ONTAP 9.6 and later: Weekly SPARES_LOW Autosupport are being sent following a disk replacement
During upgrade (ONTAP and FW)	Why do nodes report SPARES_LOW during an upgrade? ONTAP low spare alert during firmware update False-positive spares low message during DQP file update
Flash Pool / Storage Pool	Weekly SPARES_LOW error for a Flash Pool or Storage Pool aggregate Not enough spare disks for hybrid aggregate during takeover No Spares Low warning generated for hybrid aggregate
ONTAP Callhome events / Wellness Risks	(SPARES_LOW) ERROR - AutoSupport message SHUTDOWN PENDING (degraded mode) CRITICAL - AutoSupport message Node shutdown with "monitor.shutdown.brokenDisk:EMERGENCY Active IQ Wellness Risk: No spares available
Takeover or Giveback	Low spares warning on a storage pool due to partial giveback
Metrocluster	SPARES LOW autosupport triggered from MetroCluster node SPARES_LOW autosupport after switchback Not enough spares in MetroCluster pool with ADP configuration Spare drive auto-partitioned with spare_low condition for container
