Issue/Introduction

Whenever a Storage I/O error occurs that impacts the NSX Manager VM, NSX Manager is configured to throw a kernel panic, generating a trace that ends in the following:

"end Kernel panic - not syncing: EXT3-fs: panic from previous error:"

Environment

VMware NSX Data Center for vSphere

Resolution

Identify possible storage issues on the ESI host where the NSX Manager VM resides from /var/log/vmkernel.log for messages like the following:

Restore the external storage connectivity that NSX Manager is dependent on, and then re-power the NSX Manager VM.
