You should check that with IBM support.

You have a DataDomain that you are using as a VTL and have create a changes of the model L180 and have created IBM LTO3 tape drives.?

Yeah

If yes, has the FC connection between the DD and the backup server done corretly ?

Yeah

If yes, did you can the new devices into the OS ?

Yeah

If yes, does the command - lsdev -Cc tape, display the drives?

Yeah

If yes, does the command inquire display the auto changers and tape drives?

Yeah

If yes, then please delete the configuration and re-configure the tape library in NetWorker.

Yeah

so you mean that i needed atape driver?

Not sure what you talking about ...

server：win2003+nw 7.6

Library：EMC DD640 OR DD620，change：L180 ，drive：IBM LTO3

client：IBM AIX 6100-06-03-1048

So this is a NW/Windows server using a DD and LTO drive, most likely locally attached.

The client is an AIX host. It is obviously not a storage node - so no attached devices.

However, this is obviously an AIX command.

So why would a client care about a non-existing tape drive? - What am I getting wrong?

@Redliquid,

Let's see if i understand you right, cause the info you have provided is a little fuzzy.

You have a DataDomain that you are using as a VTL and have create a changes of the model L180 and have created IBM LTO3 tape drives.?

If yes, has the FC connection between the DD and the backup server done corretly ?

If yes, did you can the new devices into the OS ?

If yes, does the command - lsdev -Cc tape, display the drives?

If yes, does the command inquire display the auto changers and tape drives?

If yes, then please delete the configuration and re-configure the tape library in NetWorker.

i am not must install atap driver?

Since you use IBM drives, supplied drivers by AIX should be enough.  For example:

root:/tmp # lslpp -L all | grep -i tape

  devices.fcp.tape.rte      7.1.2.15    C     F    FC SCSI Tape Device Software

  devices.iscsi.tape.rte     7.1.0.0    C     F    iSCSI Tape Software

  devices.scsi.tape.diag    7.1.1.15    C     F    SCSI Tape Device Diagnostics

  devices.scsi.tape.rspc     7.1.0.0    C     F    RISC PC SCSI Tape Device

  devices.scsi.tape.rte     7.1.2.15    C     F    SCSI Tape Device Software

Sorry, wrong host (where robotics only is).  On host where I have drives I use atape:

root:/ # lslpp -L all | grep -i tape

  Atape.driver              12.6.0.0    C     F    IBM AIX Enhanced Tape and

  devices.fcp.tape.rte      7.1.1.15    C     F    FC SCSI Tape Device Software

  devices.iscsi.tape.rte     7.1.0.0    C     F    iSCSI Tape Software

  devices.scsi.tape.diag    7.1.1.15    C     F    SCSI Tape Device Diagnostics

  devices.scsi.tape.rspc     7.1.0.0    C     F    RISC PC SCSI Tape Device

  devices.scsi.tape.rte     7.1.1.15    C     F    SCSI Tape Device Software

Note also that error you get seems to indicate something being wrong with config of driver... and it might be compatibility of HBA... for example, see dW:AIX and UNIX:AIX Forum:Trying to access HP LTO3 FC tape drives under AIX 5300-05-03

thanks

Not sure I understand, but yes install it if you have proper package and credentials.  If not, leave it to AIX admin.
