Monitoring and protecting the file system consistency using NVFAIL

Summary

Hi I have seen a KB recommending to add a step to shut down hosts when enabling nvfail again ..is this needed ?

ref: https://kb.netapp.com/onprem/ontap/hardware/lun_online_fails_with_Error_%22_The_volume_is_in_nvfailed_state%22

Recovering LUNs in NVFAIL states after switchover

Steps

Clear the NVFAIL state on the affect volume that hosts the LUNs by resetting the -in-nvfailed-state parameter of the volume modify command.

Bring the affected LUNs online.

Examine the LUNs for any data inconsistencies and resolve them.

This might involve host-based recovery or recovery done on the storage controller using SnapRestore.

Bring the database application online after recovering the LUNs.
