Need to change the host name on the client

Hello Experts,

We installed netbackup client on one of solaris server and tested backup it was successfull. Few hours later We came to know that its host name got

changed on the client.so pls suggest how to change the client name so that successfull backup can happen.

I have only two solutions remove nbu client on solaris server and when it prompts for the client name while installing  i will give it new host name but that

requires uninstalling and

installing client again and one to change the client entery on bp.conf file. But for bp.conf i am not sure :( pls help

There might be some way to reduce this lenghy installing and uninstalling nbu process.
