Media server Fibre Transport device is offline
If NetBackup shows that a media server FT device is offline, the selected SAN client cannot detect the target mode driver on that media server. FT device status appears in the Media and Device Management > Devices > SAN Clients window of the NetBackup Administration Console. (An FT device represents the HBA target mode driver on a media server.)
An FT device may be offline because of the following:
The nbfdrv64 service on a media server is down. The nbfdrv64 service manages the target mode drivers; if it is down, the FT device is not available.
The physical connections between the SAN client and the SAN switch fail or were changed.
SAN zoning changes removed either the media server or the SAN client from the zone.
The SAN client failed the FT service validation.
If all media server FT devices for a client are offline, troubleshoot in the following order:
Verify that the SAN client FT service validation passes.
Verify that the physical connections from the SAN client to the SAN switch are correct.
Verify that the SAN zones are correct.
Verify that the nbfdrv64 service is active on each media server.
To determine if the nbfdrv64 service is down, use the operating system process status command to examine the processes on the media server. Both nbftsrvr and nbfdrv64 should be active.
If the services do not start, examine the log files for those services to determine why they do not start.
