bperror -S 48 -r
client hostname could not be found
The system function gethostbyname() failed to find the client's host name.
Verify that the client name is correct in the following:
* The NetBackup policy configuration on the master server.
* The General tab in the following dialog boxes: NetBackup Client Properties and Specify NetBackup Machines and Policy Type (on Microsoft Windows and NetWare nontarget clients). To display these dialog boxes, start the Backup, Archive, and Restore interface on the client. For the General tab, click NetBackup Client Properties on the File menu; click Specify NetBackup Machines and Policy Type on the File menu.
* The bp.conf file on UNIX, Linux, and Macintosh clients.
* The bp.ini file on NetWare target clients.
* On clients and servers, verify that the name service is set up to resolve the NetBackup client names correctly.
On UNIX and Linux clients, verify that the client's host name is in the /etc/hosts file or the YP hosts file or NIS maps
.
Have you tried to 'ping' the client from the master and media server?
First of all, check that spelling of client name is correct in the policy, then try to ping the client name.
If ping fails, check the name resolution used in your environment - either hosts files or DNS.
If hosts, verify entries on master and media server for the client.
Please also check if client has hosts entries for master and media server.
