7184:savefs: nothing to save
Hi,
Details:-
We have two server server1v.net and server1n.net is backing up on backup server.
server1v.net
server1n.net
Server1v.net is the virtual name of server1n.net and both's IP are diffrent.
Both server is added on same backup server but one is failed and one is successfully backed up.
server1n.net --- Backing up successfully.
server1v.net --- Backup is failing with below error.
1 retry attempted
7184:savefs: nothing to save
savefs server1v.net failed.
: Failed with error(s)
As per some post from EMC I have checked below condition.
Restart the networker remote exece service...ok
nslookup from server and client side -----OK
Client instance deleted and again add ---but no luck to resolved
Checked servers file entry --- ok
Also check hosts file of server1v ...there is only 127.0.0.1 entry......
Anyone know why this backup is failing with error savefs: nothing to save.

Hi,
We have removed physical node from backup and "All" save set replaced with individual save set and it backing successfully.
Carlos :-
we will not recover a physical server from backup.. Since they are in a multi-node cluster we will just rebuild a physcial from scratch in we have to.. we do care about the virtual stuff.. server1v or server2v thats the actual data we care about.
Thanks to reply all admin.

Also try running savefs -p command on both client and provide me with the output you get.
Check if you have an issue with name resolution, can you check forward and reverse lookups on both client and server (both short name and FQDN)
Additionally, run the command rpcinfo -p clientname , from the backup server to the clients (FQDN and short name) as well as from the clients to the backup server.
Finally check if there is any alias missing either in the hosts file or in the client resource configuration.
Waiting your updates.
Thanks,

Hi moin,
Sorry i didnt get what you mean by "Server1v.net is the virtual name of server1n.net and both's IP are diffrent." Is that mean physical and virtual (Cluster scenario ) or you mean physical machine and VM machine.
Are they backing up the same machine, but this machine is multihomed NIC , where there is two IP addresses configured on it ?
Would you please clarify more the configurations , but mainly it seems to be name resolution issue or communication , but i would like to understand firstly the configuration of the two servers and the relationship between them.
Thanks,
Ahmed Bahaa

Hi Moin,
I think the main problem here is the configuration.
It's important that you understand how NetWorker works with clusters, and for that I would recommend you to take a look at the Cluster Installation guide:
Home > Support > Technical Documentation and Advisories > Software ~ J-O ~ Documentation > NetWorker Family > NetWorker > 7.6 & Service Packs
NetWorker 7.6 Service Pack 2 Cluster Installation Guide
Here you will find information about how to install the software and how to configure clustered clients in NetWorker.
Please follow those steps and if you have any further question or issue let us know.
Thank you.
Carlos.

Server1v.net
Server1n.net
Yes it is the Cluster scenario.
Server1v.net Virtual server
Server1n.net Physical Node
Savefs -p from Virtual server:-
C:\>savefs -p 77592:savefs: 'NSR client' resource named 'Server1n.net' not found.
7185:savefs: cannot retrieve client resources
Savefs -p from Physcial node server:-
C:\>savefs -p 77592:savefs: 'NSR client' resource named 'Server1n.net' not found.
7185:savefs: cannot retrieve client resources
forward and reverse lookups on both client and server are checked it is ok.
rpcinfo working fine:-
bash-3.00$ rpcinfo -p Server1v.net
program vers proto port service
100000 2 tcp 7938 portmapper
100000 2 udp 7938 portmapper
390436 1 tcp 9121
390435 1 tcp 9626
390113 1 tcp 7937 nsrexec
bash-3.00$ rpcinfo -p Server1n.net
program vers proto port service
100000 2 tcp 7938 portmapper
100000 2 udp 7938 portmapper
390436 1 tcp 9121
390435 1 tcp 9626
390113 1 tcp 7937 nsrexec
Alias in the client resource configuration is ok.
Finally check if there is any alias missing either in the hosts file, >>>added hosts entry and tried to take test backup failed

Also please provide me the log file output of the following commands:
savegrp -D9 -c Server1v.net adhoc > debug.log
You can attach it here.

Hi Moin,
Try to do the following from the backup server to the networker client ( using short name and FQDN name):
If this all works perfectly and resolution is good, try to do the following from the client to the backup server ( using short name and FQDN name):
Thanks,

Hi,
First thank you very much for reply
savegrp -D9 -c Server1v.net adhoc > debug.log
Above command ouput are attached
I rechecked all below conditions/output are correct:-
networker client ( using short name and FQDN name):
•check hosts-file if you can find the client
•ping
•nslookup
•rpcinfo -p
backup server ( using short name and FQDN name):
•check hosts-file if you can find the backup server
•check server file under the nsr directory if the backup server is added there
•ping
•nslookup
•rpcinfo -p

Hey Moin,
You are talking about a cluster, but only about one physical node and one virtual node, isn't there a secondary physical node? Otherwise I don't really understand the "cluster" concept in this scenario.
Is it MSCS or Load Balancing?
If it's MSCS cluster, I would like to know why would you like to backup the virtual node instead of the physical nodes. When running backup with saveset "All", the active node owning the clustered disk should be backing up the clustered disks, so no need to backup the virtual node.
Anyway we should know a bit more about the IP/NIC configuration in this environment.
Have you tried to add the IP to the alias field, apart from the short names and FQDN in both, physical and virtual nodes?
Thank you.
Carlos.

Hi,
Yes, it is having 2ndry physical node.
server2n other virtual client server2v
And above both are backing up successfully.

Hi Moin,
Still not clear. So how many physical and virtual nodes do you have for this cluster?
You mentioned:
server1n
server1v
server2n
server2v
For me this looks like 2 physical nodes and 2 virtual nodes, is this correct?
If so, have you tried backing up only the physical nodes?
Do you have at least created one client resource for all the nodes? (All physical and all virtual with correct aliases in the Alias Field).
What about the output of the tests Ahmed was suggesting?
Thank you.
Carlos

Hi,
Yes you are right bro.
These are 2 Physial and 2 Virtual Node.
I dont't understand your point "how is these servers are configured ? "...Please provide me in details.
And also i checked commumnication and connectivity ..it is working fine.
Yes I have configured all virtul ad all physical node and Ip address in Alias.

Hi Moin,
Did you try backing up the physical nodes ? are they backing up successfully ?
Thanks,
