RAID Layout Cannot Be Autocorrected - AutoSupport message

Applies to

• ONTAP 9
• DS460
• callhome.disk.carrier.evacuation.notpossible

Event Summary

This message occurs when a system does not contain enough spares to correct existing disk failures.

• This message is seen only on systems containing disk carriers capable of holding more than one disk.
• When this message occurs, manual intervention is required because ONTAP cannot automatically correct the existing issues with the system''s disk configuration.

Validate

• Event logs will report a disk carrier evacuation not possible error:

event log show -severity alert -event *notpossible*

HA Group Notification from node_name-02 (RAID Layout Cannot Be Autocorrected Carrier: 7904453323, Disk: 3.20.13.1) ALERT

• AutoSupport alert:

[node_name-02: raid_lm: callhome.disk.carrier.evacuation.notpossible:alert]: Call home for DISK_CARRIER_EVACUATION_NOTPOSSIBLE

Resolution

1. Assign any unassigned disks that are contained within a multidisk carrier.
2. Add multidisk carriers.
3. If a replacement carrier is available, do the following:
   1. Fail ALL disks within the carrier. Do not remove a multidisk carrier that contains non-failed disks; doing so results in system degradation and might result in system failure.
   2. Wait until the disk''s amber Attention LEDs stop flashing and are lit continuously. Do not remove a carrier while the shelf OPS panel is alternating between the shelf ID and the Attention Code H1, or while the disks within the carrier are flashing their amber Attention LEDs.
   3. Replace the carrier.
4. Reassign partner spare disks in the HA configuration.
5. If the problem persists, contact NetApp Technical Support.
