Ping Failed on Host - while requesting host info but ping does work!

Hi everyone,

Maybe someone can help with this seemingly inocent issue.

I have a NBU 7.1 master clustered with clients in Windows 2008R2. When i request the host's information i get ping failed on host <hostname>.

The ping however works fine to and from the client or master/media servers. I tried also to disable the option "Disable 'ping' connection checking" in the NBU options but it still fails.

Can anyone elucidate this issue?

DNS and pings do work well in forward or reverse for the client, the media servers and the master servers from the cmd.

Backups still work despite this. 

Other details: vnetd is in use.

 

Thanks for any infos

You may try turning off the windows firewall in client.

did you try bpclntcmd , bptestbpcd commands from master, media and client. If yes, please share the output

I cannot turn off the 2008 firewalls. I suspect my issue comes from there. But the icmp rules and netbackup rules are ok. I dont see why it all works except when i try to get the host properties. Again, the ping works both ways but NBU says it doesn't.

bpclntcmd works from nbu servers or host.

Returns the correct ip of the host and it's aliases. FQDNs are in use everywhere.

bptestbpcd also works fine.

From the master

D:\Veritas\Scripts>bptestbpcd -host vroom2  -connect_options 0 1 1
0 1 1
10.254.232.49:1082 -> 10.254.232.104:13724
10.254.232.49:1100 -> 10.254.232.104:13724

From the media:

C:\Home\ed240adm>bptestbpcd -client vroom2 -connect_options 0 1 1
0 1 1
10.254.224.69:2912 -> 10.254.232.104:13724
10.254.224.69:2917 -> 10.254.232.104:13724
10.254.224.69:2921 -> 10.254.232.104:13724

C:\Program Files\VERITAS\NetBackup\bin>bpclntcmd -pn

Did you try adding the NBU services to firewall exception, instead of turning it OFF.

Hi

Same i faced at one of my customer... This made me think for almost 30-40 mins .. and reckoned it was wrong entry in host file.. 

at glance it was looking perfect but found it incorrect (period was missing)... 

 

Can you check .. if host files at both nodes are properly configured.

i had similar issue, Disabling Chimney solved this issue.

Run the following command on master and client
netsh int tcp show global
netsh int tcp set global chimney=disabled
