hyper-v backup is failing
Dear Experts!
Our customer uses NW 9.0.1 and Hyper-v 2012 hosts is CSV configuration.
We set up the NMM VSS image backup, it is worked, but currently is not working.
We have to figure out what caused this error.
We starting the backup but we doesnt get any relevant information.
We set up the -D9 switch on the backup command (nsrnmmsv -D9) and we found some
interesting things:
1. case:
107092:nsrnmmsv: Version information for C:\Program Files\EMC NetWorker\nsr\bin\nsrnmmsv.exe: Original file name: nsrnmmsv.exe Version: 9.0.1.669 Comments: Supporting Microsoft Volume Shadow Copy Service
06/16/17 13:49:47.755820 Reverse DNS lookup failed for fe80::c8c4:4293:4c32:ec5e: No such host is known.
06/16/17 13:49:47.755820 clu_init:ENTRY
06/16/17 13:49:47.755820 calling clu_init_lc()
06/16/17 13:49:47.755820
clu_init_lc(): ENTRY...
06/16/17 13:49:47.755820
It shows that nsrnmmsv cannot resolve the ipv6 address.
The customer doesnt use ipv6 but MS said it is required when we use failover cluster.
2. case:
clu_hosts_matchbyname() comparing 10.0.124.210 and cluster.dns.address
clu_hosts_matchbyname:ENTRY
host1=10.0.124.210, host2=hostname.dns.address
clu_hosts_matchbyname:EXIT: b_ret=0
nsrnmmsv NSR notice 5 %s %s 2 0 24 06/16/17 13:49:59.771854 0 35 clu_hosts_matchbyname:EXIT: b_ret=0
It seems that host cannot resolve 10.0.124.210 address as a cluster.dns.address,
but it is working well from command line.
- This setup is worked well until the customer rebooted all the hv servers.
- Hyper-v wizard is working well
We have multiple ip addresses and dns names:
- cluster dns name
- hyper-v host name
Do you have any suggestions how can we continue?
Many thanks in advance!
