IPv6 support for BMR
Bare Metal Restore (BMR) provides protection to clients that can communicate over an IPv4-only network, an IPv6-only network, or a dual stack IPv4-IPv6 network. BMR recovery is yet supported only over IPv4 network as many NW boot protocols are not supported over IPv6 channel. In addition, when you configure a BMR database with the bmrsetupmaster command, the BMR master server IPv4 address needs to be enabled and able to resolve with the master server host name. Once bmrsetupmaster runs successfully, you can bring the IPv4 address down if you only want to use the IPv6 address.
During the BMR restore time, the master server and the media servers need to have IPv4 addresses up.
A bmrsetupmaster may fail while BMR resolves its master's IPv4 address during its record creation into BMR database. As the BMR database creation fails, the BMR master does not function.
To resolve this issue, make sure an IPv4-based IP of the master server is enabled and can be resolved using the NetBackup master server name before you run the bmrsetupmaster command.
Note, the BMR backup is supported on IPv6 network channel, however, the BMR restore works only with IPv4 channel.
