症状

Avamar monitoring status for Data Domain changes to Yellow or Red from Green on the Avamar Administrator UI.

 
One or more of the following errors may appear in the Avamar UI.
  • Error: Unable to get SNMP file system status
  • Error: Unable to get file system information
  • Error: Unable to get disk status
  • Error: Unable to retrieve ssh keys

原因

There is an incorrect SNMP configuration on the Data Domain.

If SNMP is not configured correctly on the Data Domain this results in SNMP errors on the Avamar Administrator UI.

解决方案

Verify that SNMP is configured correctly on the Data Domain:

 

1. Log in to the Avamar Utility Node and load the keys: Avamar: How to Log in to an Avamar Server and Load Various Keys.

2. Access the Data Domain server in Admin or System Engineer (SE) mode: How To Access a Data Domain System from an Avamar Server

3. Check the SNMP configuration:

snmp show config
General Configuration
---------------------
   SNMP sysLocation:
   SNMP sysContact: SNMPsyscontact@mail.com

SNMP v2c Configuration
---------------------
   Community    Access      Host
   ----------   ---------   -----
   public1      read-only   *
   public11     read-only   *
   publicuser   read-only   *
   test         read-only   *
   ----------   ---------   -----


   Trap Host              Port   Community
   --------------------   ----   ---------
   examplehost            163
   examplehost2           163
   137.xx.xx.xxx          163
   AvamarTest             163
   10.xx.xx.xx            163    test
   --------------------   ----   ---------

SNMP v3 Configuration
---------------------
   User   Access   Authentication Protocol   Privacy Protocol
   ----   ------   -----------------------   ----------------
   ----   ------   -----------------------   ----------------

   Trap Host   Port   User
   ---------   ----   ----
   ---------   ----   ----
 
Notes:
 
  • The community string on the Data Domain (that Avamar uses) is recommended to be a read-only community string
  • The community string on the Data Domain (that Avamar uses) should be associated with the Avamar hostname or the wildcard "*"
 
 

4. Check that the SNMP trapd service is enabled on the Data Domain:

snmp trapd status

Output:

SNMP Trapd is enabled.

-- Or --

SNMP Trapd is disabled.

 

If it is disabled: Use the following command to re-enable it:

Warning: If the Data Domain version is greater or equal to 5.5.x, do not enable the trapd service.

See Data Domain: The importance of keeping SNMP trapd disabled
  
snmp trapd enable

Confirm the status to verify it is now enabled:

snmp trapd status
 

5. Restart the SNMP service for Data Domain on Avamar after making the SNMP configuration changes.

This can be done using the following steps. 

a. Return to the Avamar Utility Node.

b. Switch to root privilege.

c. Restart the SNMP service:

mcddrsnmp restart
 

d. Allow the SNMP service approximately 3-5 minutes to update the status on the UI after running the command.

6. If the issue is still not resolved, review the resolution path for SNMP issues per Avamar: Troubleshooting Data Domain Integration Reporting Errors in the Avamar Administrator UI (Resolution Path).
