NetBackup 4.5 Troubleshooting Guide for Windows
If none of the comparisons succeed, a more brute force method is used, which compares
all names and aliases using gethostbyname().
The configured name is the first comparison that succeeds. Note that other comparisons
might also have succeeded if aliases or other “network names” are configured.
If the comparison fails, the client’s hostname as returned by the gethostname()
function on the client is used as the configured name. One example of why the
comparison could fail is the case where the client had changed its hostname but its new
hostname is not reflected in any policies yet.
These comparisons are logged in the bpdbm debug log if VERBOSE is set. You can
determine a client’s configured name by using the bpclntcmd command on the client.
For example:
# install_path\NetBackup\bin\bpclntcmd -pn
expecting response from server wind.abc.me.com
danr.abc.me.com danr 194.133.172.3 4823
Where the first output line identifies the server to which the request is directed and the
second output line is the server’s response in the following order:
◆ Peername of the connection to the server
◆ Configured name of the client
◆ IP address of the connection to the server
◆ Port number used in the connection
When the client connects to the server, it sends three names to the server:
◆ browse client
◆ requesting client
◆ destination client
The browse client name is used to identify the client files to list or restore from. The user
on the client can modify this name to restore files from another client. For example, on a
Windows client, the user can change the client name by using the client user interface (see
the user’s guide for instructions). For this to work, however, the administrator must also
have made a corresponding change on the server. For more information, refer to the
NetBackup System Administrator’s Guide for Windows.
The requesting client is the value from the gethostname() function on the client.
The destination client name is a factor only if an administrator is pushing a restore to a
client from a server. For a user restore, destination client and requesting client are the
same. For an administrator restore, the administrator can specify a different name for the
destination client.
