SAN client Fibre Transport service validation
The SAN Client Fibre Transport Service (nbftclnt) validates the client system's kernel and driver stack when it starts and during device discovery. Validation verifies that the kernel and the drivers are at supported levels.
If validation succeeds, the SAN client supports FT pipe transfers; FT pipe transfer can occur. If validation fails, FT pipe transfer cannot occur.
To manage the validation failure, the following occurs:
The SAN Client Fibre Transport Service writes check driver messages in its log file.
NetBackup sets the FT device status to offline for all FT target devices in the client's SAN zone. (For other clients in the zone that pass the validation, the FT devices are online.)
To see the FT device status from the client, select the client in the Media and Device Management > Devices > SAN Clients window in the NetBackup Administration Console.
The check driver messages in the nbftclnt log file are similar to the following:
VerifyCheckConditions:failed on <OS Device Name> - check driver VerifyCheckConditions:failed on <OS Device Name>; <System Error Message>
The following describes the variables in the messages:
OS Device Name is the device name the SAN Client uses to open the OS device driver.
System Error Message can be any OS-dependent system error message for a failure that is associated with the request.
If validation fails, install the correct operating system version, operating system patches, or driver version.
For supported kernel and driver levels, see the NetBackup Release Notes.
