I need some expert advice here. I am in the process of configuring NDMP to NB server on celerra NS40.The problem is the media server as well as the master server is not able to ping the DM IP.
What could be the possible reason for the backup server not able to communicate with the DM? i 'd also like to know if i can add route entry on the server 198.199.241.50 for 206.245.36.0/24 subnet( these are the backup servers) with the next-hop 198.199.241.33.
Destination Gateway Mask
206.245.36.0 198.199.241.33 255.255.255.0
would this help? Adding a new route should not impact the production?
somebody told me, I do not have an interface called DIRECT LOCAL so traffic can't get off the DM.DIRECT LOCAL doesn't exist but is used for route.
please shed some light on this ...Very much appreciate your help. Let me know if any other output will be required?
when EMC told you to use server_2 ..he/she is basically verifying that NDMP port is listening. If you look at /etc/hosts file on control station you will see that it's assigned an inernal to Celerra ip address, for example:
so if you telnet to server_2 you are actually connecting to internal interface on datamover. If you are successful with that, that means NDMP is listening and it's something on the outside network that's preventing NDMP connection (firewall, ACL on the network switch).
You are using different Vlans (1514 and 1526) and you have set this vlan ids on the interfaces, so you have disabled vlan tagging on the switch.
Are your backup servers also sending this vlan id?
Because if there will be network packets to the usdadcgfspuw00 interface, which is 206.245.41.14, these must be vlan taged with 1526 or the Datamover will ignore it.
usdadcgfspuw00 is the only VDM created. What changes you suggest to make in order to enable VLAN taggin on the switch?
How can i check the backup server in havin' the same VLAN ID . Is there a comand to run on the Master server ( Unix Box) / Media server( windows boxes) to check this? i can ask the Backup guy to have a check on it.
Rainer thanks for the suggestion! i 'll get this verified by the network admin .Meanwhile-
One thing I 'd also like to know if i can add route entry on the server 198.199.241.50 for 206.245.36.0/24 subnet( these are the backup servers) with the next-hop 198.199.241.33.
Destination Gateway Mask
206.245.36.0 198.199.241.33 255.255.255.0
Would this step help provide access to the gateway?
Just to update - the back up interface is able to ping the DM now , the only change was done on the firewall setting b/w the DM and backup interface.
But another problem cropped up - now, with the telnet.
I can telnet my Datamover , but, the backup server is not able to. onething, why is it showing 128.221.252.2 as the Ip?
telnet server_2 10000 Trying 128.221.252.2... Connected to server_2 (128.221.252.2). Escape character is '^]'. $M#R PuTTYhelp
================================
when i can listen to the port 10000 and telnet to it. The backup server is able listen to it but not telnet ,don't think there could a firewall or something obstructing it...

[nasadmin@ns20 ~]$ cat /etc/hosts |grep -i server_2
192.168.1.2 server_2 #DART_data_mover_2
so if you telnet to server_2 you are actually connecting to internal interface on datamover. If you are successful with that, that means NDMP is listening and it's something on the outside network that's preventing NDMP connection (firewall, ACL on the network switch).
