To troubleshoot an IPv6 network error
1
Verify that the IPv6 interface has a global address.
Run the following command in the NetBackup Appliance Shell Menu:
Main_Menu > Network > Show Configuration
In the output, under one of the eth headings (eth0, eth1, etc.), look for an
entry similar to the following:
inet6 addr: 2001:db8::2/64 Scope: Global
The scope of at least one address must be global. If a global scope address
does not appear in the command output, reconfigure the IPv6 address.
2
Verify the network routing path with the Main_Menu > Network > Gateway
Show IPv6 command. Check the routing table for any errors. If any of the
network path information is incorrect, enter the correct information. You can
use the Network view commands in the shell menu or the Settings > Network
page of the NetBackup Appliance Web Console.
See the NetBackup Appliance Command Reference Guide and the NetBackup
Appliance Administrator's Guide for more information.
3
Check communication with the default gateway. The gateway IP address is
shown in the routing table that displayed in the previous step.
Use the Main_Menu > Network > Ping Host command to test communication
with the gateway. In this case, Host is the IPv6 address of the gateway.
If the gateway is not reachable, contact your network administrator to check
the gateway status.
4
Check communication with the host with the Main_Menu > Network > Ping
Host command, where Host is the host name or the host IPv6 address.
If the host is not reachable, run the Network > TraceRoute Host command
to check for problems along the network path.
5
If you experience an IPv6 issue with a feature that previously worked over an
IPv4 network, ensure that NetBackup now associates an IPv6 address with
the host name or host names.
Add a host name to the IPv6 network with the following command:
Main_Menu > Network > Hosts Add IP_Address FQHN Short_Name
where IP_Address is the IPv6 address, FQHN is the fully qualified host name,
and Short_Name is the short host name.
See “About IPv4-IPv6-based network support” on page 26.
