Products

Issue/Introduction

 

• You're running NSX-T Data Center.
• You've recently hardened the Bare metal server after it was prepared for NSX-T.
• The applications hosted on the Bare metal server would not be accessible form NSX.
• The file "/etc/vmware/nsx-bm/bms.conf" is not present in server.
• If you run ls -l on the /tmp you will notice execute permission is not present on the directory.

Environment

VMware NSX-T Data Center

Cause

The Bare metal server was hardened, after it was prepared for NSX-T, which changed permissions on the /tmp directory.

Resolution

The /tmp directory has important executable scripts necessary for updating and creating segment ports on the bare metal server, disabling the execute permission to /tmp directory will cause the bms.conf file to be deleted.
