NetBackup™ SAN Client and Fibre Transport Guide

SAN client does not select Fibre Transport

If either of the following are true, a SAN client may not be able to select Fibre Transport during a backup or restore operation:

  • The FT media server host operating system domainname command returns fully qualified domain names and NetBackup is configured to use short names.

  • The FT media server host operating system domainname command fails because of: DNS, NIS, or network problems and NetBackup is configured to use fully qualified domain names.

If so, the backup or restore may fail or it may occur over the LAN rather than the SAN.

To work around this problem, add an alias for the FT media server to the EMM database.

The following are the command syntaxes:

  • To add a short name alias:

    nbemmcmd -machinealias -addalias -alias shortservername 
    -machinename servername.fully.qualified -machinetype media
  • To add a fully qualified domain name alias:

    nbemmcmd -machinealias -addalias -alias 
    servername.fully.qualified -machinename shortservername 
    -machinetype media
