NetWorker: Sådan indtastes FQDN-værtsnavnet for NetWorker-klienten i nsrla-databasen

NetWorker-klienten blev føjet til NetWorker ved hjælp af dens fuldt kvalificerede domænenavn (FQDN):

[root@nsr ~]# nsradmin
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> print type: nsr client; name: rhel-client01.amer.lan

Ikonet nsrladb på klienten genereres med shortname. 

[root@rhel-client01 ~]# nsradmin -p nsrexecd
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> show name
nsradmin> p type: nsrla
                        name: rhel-client01;
nsradmin>

NetWorker opretter /nsr/res/nsrladb med det værtsnavn (kort eller FQDN), som det modtager fra operativsystemet i løbet af den tid, det opretter databasen.

1. Åbn en administratorkommandoprompt eller rodshell på NetWorker-klienten.
2. Stop NetWorker-klienttjenesterne:

Linux: nsr_shutdown
Windows: net stop nsrexecd /y

3. Åbn operativsystemets værtsfil:

Linux: /etc/hosts
Windows: C:\Windows\System32\drivers\etc\hosts

4. Kontroller, om der er modstridende poster i værtsfilen for klientens navn. I dette tilfælde vises værtsfilposten f.eks. som:

192.168.9.121   rhel-client01   rhel-client01.amer.lan

Det korte navn vises før FQDN, så da NetWorker-klienttjenesten startede, oprettede den nsrladb ressource ved hjælp af shortname.

Ret værtsfilen, så NetWorker-klientnavnet er det fornavn, der er aliaseret for IP-adressen, f.eks.:

192.168.9.121   rhel-client01.amer.lan  rhel-client01

5. Omdøb nsrladb fil:

Linux: /nsr/res/nsrladb
Windows: C:\Program Files\EMC NetWorker\nsr\res\nsrladb

6. Start NetWorker-klienttjenesterne:

Linux: systemctl start networker
Windows: net start nsrexecd

7. Brug nsradmin til at bekræfte, at klienten har det korrekte navn i sin nsrladb:

nsradmin -p nsrexecd
show name
print type: nsrla

[root@rhel-client01 ~]# nsradmin -p nsrexecd
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> show name
nsradmin> print type: nsrla
                        name: rhel-client01.amer.lan;
nsradmin>

8. Åbn en administratorkommandoprompt eller rodshell på NetWorker-serveren. 
9. Kontroller, om der er peer-konflikter vedrørende klienten: nsradmin -C -y -p nsrexecd "nsr peer information"

[root@nsr ~]# nsradmin -C -y -p nsrexecd "nsr peer information"

Validate "nsr peer information" resources

Synopsis: For each NSR peer information resource in nsr.amer.lan's NSRLA database, verify the 'NW instance ID' and 'certificate' attributes match those found in the peer's NSRLA resource.

 Hostname: rhel-client01
 Instance ID: ca782745-00000004-c0984de0-68532545-00015000-a61cbe56

 * The "NSR peer information" resource for rhel-client01 in nsr.amer.lan's NSRLA database is out of date. The "NW instance ID" attribute does not match the one stored in rhel-client01's NSRLA resource. To correct the problem, delete the NSR peer information resource for rhel-client01 in nsr.amer.lan's NSRLA database.

 * Deleted "NSR peer information" resource for rhel-client01 from nsr.amer.lan's NSRLA database
