    In addition to the above post, If it has been working but has now gone down it may be a timeout / communications error during busy periods

    It is always worth adding a touch file on your Master and Media Servers as follows:

    /usr/openv/netbackup/db/config/DPS_PROXYDEFAULTRECVTMO

    edit (vi) this file and just put a value of 800 into it

    Then re-start NetBackup on each Server to register this change

    This just helps with communications during busy periods

    As you pool is not coming back up this may not solve it completely so it is worth checking through the admin log on the Master as well as a vxlogview against nbrmms (222) plus enabling the ost-plugin logs

    Let us know what you find or post the logs on here

The cause was i enabled the jumbo frames at the master server and the data domain and also de switch because I have a 10 GB network connection but very poor network performance.

I need to go back and set the mtu to 1500 as initial was at the master server and the data domain, and 1514 at the switch level.

 

I still have low perfornce but i have adjusted at the master server the NET_BUFFER_SZ and NUMBER_DATA_BUFFER so the performance was better but no as it could be.

 

I would like to know If anybody knows how to enable the jumbo frames

 

Best regards.
