Description

 

This article describes how to identify the FortiGate device associated with an integrity check error.

 

Scope

 

FortiManager.

 

Solution

 

While running a device database integrity check, 'diagnose pm2 check-integrity device', errors may be reported for one or more managed devices. These errors reference an internal device database file that includes the device ID.

For example:

 

diagnose pm2 check-integrity device
--- pragma integrity_check device db ---
pragma integrity_check fails: /var/pm2/devdb447 -- Page 5596: never used

 

In this output, the number appended to /var/pm2/devdb represents the device ID.

 

Steps to identify the device:

  1. Take a note of the number following "/var/pm2/devdb". In the above given example, it is '447'.
  2. List managed devices by running the command 'diagnose dvm device list' in the FortiManager console. The output will look like this:

     

FMG-VM64 # diagnose dvm device list
--- There are currently 63 devices/vdoms managed ---
--- There are currently 63 devices/vdoms count for license ---

TYPE OID SN HA IP NAME ADOM IPS FIRMWARE HW_GenX
fmgfaz-managed 447 FGT30GTK******52 - 10.25.33.254 FGT-LAB root 7.0 MR4 (5164) N/A
|- STATUS: dev-db: modified; conf: out of sync; cond: Modified; dm: aborted; conn: up; source: FMG
|- vdom:[3]root flags:0 adom:root pkg:[modified]Spoke tmplgrp:[installed]Default Template

 

  1. Identify the device with the OID matching the number found in step 1.

     

In this example, the device name is FGT-LAB in the ADOM root.

 

Notes:

  • The following command can also be used to extract device information:

FMG-VM64 # diagnose dvm device list <Device OID>
