Problem

Restoring from an Appliance Media server gives very poor performance

Error Message

Restore performance between an appliance media server and a client shows very poor performance, less than 1Mb/s. However backup performance shows excellent performance,

The issue can be seen via file transfer speeds from the media server to the client also, ruling out NetBackup software as a cause. Use nbperfchk with the client listening on a port and send data with nbperfchk to the client/port to test performance.

See article https://www.veritas.com/support/en_US/article.000095782 on how to use nbperfchk for Network Tests.

Cause

The DLink Layer Discovery Protocol–Media Endpoint Discovery (LLDP-MED) on the specific interface(port) through which the appliance is directly connected is enabled

 

Solution

Disable DLink Layer Discovery Protocol–Media Endpoint Discovery (LLDP-MED) on the specific interface(port) through which the appliance is directly connected is enabled.

One LLDP-MED is disabled test network performance with nbperfchk.
