Problem with configuring tape library

First up, the environment;

1. Backup server is on Solaris 9 with 3 HBAs.
2. One physical tape library and one virtual tape library (CDL) are connected to the backup server.
3. Each tape library has 20 LTO-II tape drives.
4. Zoning is fine and the HBA cards are working.

The problem is that inquire detects the robotic arm and 10 of the tape drives from the physical tape library but does not pick up the rest. What I found was that device files for all the tape drives are getting created on the OS. For some reason, inquire is not detecting them.

I can work around the tape drives not being detected by inquire and add them using jbedit, but the problem is that I am not able to configure the VTL as inquire is not detecting it's robotic.

Any suggestions?

    Check the fibre cable attached to that drive , if it works fine, Try to replace with the working drive to the old drive in the library . There might be a problem with the library or with the fibre cable .

    Inquire picks up 10 of the physical drives but does not pick up any of the other drives.

    Does not seem to be a problem with the fibre or the library as I am able to access the drives from the OS. Can read /write using tar commands.

    This is the same problem i have faced for two times , one time we have changed the drive and checked , then the Networker detects the drive and for the another time , the networker doesn't detect the drive and we have uninstall and reinstall the networker , then it was working fine. As you said you can able to take a backup from OS, so there will not be a problem with the fibre . If the Networker is not in production , try to reinstall it . And kindly let me know .
