Question

How to add the mapping between the IP address and host name of the storage system?

Answer

To back up data using the host name of the storage system, you need to add the backup IP address and host name of the storage system to the hosts file on the backup server. This section uses a Linux-based backup server as an example.

Log in to a backup server as an administrator and modify the /etc/hosts file on the backup server. Then add the backup IP address and host name of the storage system. For example:

10.169.60.47 nas01 is the backup IP address and host name of the storage system. 10.169.108.240 nbu-lyp is the IP address and host name of the backup server.

nbu-lyp:~ # vi /etc/hosts



#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#

10.0.0.1       localhost

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts
10.169.60.47         nas01
10.169.108.240       nbu-lyp

On the backup server, run telnet host name 10000. If the connection is successful, the configuration is correct.
- host name indicates the host name of NDMP.
- 10000 indicates the port number of NDMP.
```
nbu-lyp:~ # telnet nas01 10000
Trying 10.169.60.47...
Connected to nas01.
Escape character is '^]'.

telnet> quit
Connection closed.
