Adding a client through New Client Properties in NetWorker 19.7.0.3 does not complete and displays the following error:
Figure 1: Screenshot of Error message
Name <CLIENTNAME> is not a valid host name as it cannot be resolved in DNS. Please add it to DNS or the hosts file and flush the NetWorker server's DNS cache (dbgcommand -p <NetWorker server pid> FlushDnsCache).
Figure 1: Screenshot of Error message
原因
The hostname fails name resolution either through DNS or through the 'hosts' file.
Even if the hostname resolves, if this error message occurred previously, the NetWorker DNS Cache prevents the client from being added.
解决方案
Add the client hostname to DNS (forward and reverse entries) or add it to the 'hosts' file using the format:
IP Address [space/tab] FQDN [space/tab] Short Name
Follow the steps below to "flush" the NetWorker DNS Cache:
- Obtain the PID of the 'nsrd' and 'nsrexecd' processes using the below commands:
Windows:
tasklist | findstr nsrd.exe tasklist | findstr nsrexecd.exe
Linux:
ps -e | grep nsrd ps -e | grep nsrexecd
- Run the below command against the PID of the 'nsrd' and 'nsrexecd' and use the switch as shown:
dbgcommand -p <PID> FlushDnsCache
