If you have lots of experience configuring fiber tape drives, please help. We have Sun V210 servers with dual port HBA's. One port goes to a disk array for DSSU and one port to a Compaq 9326SL tape library. The tapes are accessed through a fiber to scsi media router (bridge) zoned by the McData switch. The DSSU part seems to work fine but many SCSI transport erros and an inability to see the drives is killing the functionality of the system. We have had HP, Sun, and Veritas working the problem with no success. We have gone over every Veritas, Sun, Qlogic, and HP doc trying to find what we are doing wrong. Experience ,guesses, and theories are welcome.

Hello,
You have first to check in /kernel/drv different files.
First is the st.conf
Second is the sg.conf
Third is the driver.conf of HBA and check if you binding well the SAN WWPN & WWNN for all tapes.
For jni is something like JNIXXX.conf

look in your netbackup install dir you should have a file called MediaMgr_DeviceConfig_Guide.txt it should explain all.

Gentlemen, We are using an HP M2402 fiber bridge. None of the basic configuration techniques work since the sg.build script cannot see the tape drives via luxadm -e dump_map which the script uses. I thought I was being slick by adding those entries to the sg.conf but then I found my lack of devlink.tab knowledge could not complete the configuration. In addition, since the disk array also is connected via fiber I am concerned that I am causing a device conflict via the sd.conf or devlink.tab because on at least one of the servers, a cfgadm -al lists the channel as failed or failing. Yes, the HBA's have been replaced. Should I be using different drivers other than the SCSA Generic (qlogic drivers)? I realize this is above and beyond the call of duty but any help would be appreciated. The vendors can't (or won't) figure it out unless we pay $14,000.
