change /etc/hosts entries without reinstalling NBU?

NBU 7.6.0.3, master/media and client; Oracle 11.2.0.3

my DBA is trying to run an RMAN script to do backups. previously on this Solaris host, the ip address of the master/media server is in 10.xx.xx.xx range as well as the ip address of this Solaris host (as known by the master/media server). although the maste/media server and the client can ping each other, the returned ip address is in the range of 192.168.xx.xx for both of them.

my question is, does the NBU client need to be reinstalled or reconfigured to recognize this change of ip address?

the error message on my NBU console is:

3/04/2015 09:20:13 - connecting

    No, NetBackup does not know what IP your system is. NetBackup works on a host level and lets the OS/DNS translate the host to IP. So you can change the IP, but you need to ensure the other hosts are updated if not using DNS. Also use: bpclntcmd -clear_host_cache to flush the NetBackup IP cache (this will happen automatically after 1 hour)

    hmm I am a bit confused about the solution as I actually answered your direct question, whereas Marianne expanded on the part of clearing the host cache.

    hi, i was debating whether to reply or not but in the end, i guess your confusion needs addressing.

    yes you replied directly to my question. short and direct. but Marianne's provided more information which helped me understand better the situation.

    i hope that clears it :)
