Hi all...
I have a scsi Tape library. Centos only sees the tape drive portion of the library. I need to enable Multiple LUN support to get the library and tape drive recognized.
I am looking for some help enabling multiple lun support in Centos 4. I had a procedure on how to do this in the 2.4 kernel but it doesn't seem to work in the 2.6. Any help would be appreciated.
Config:
Standard intel server board. p4 processor (3) 3-ware controllers Lsi Logic u320 scsi card External SCSI tape library.
Worked before on a Whitebox linux 2.4 kernel, just added: options scsi_mod "max_scsi_luns=16" to /etc/modules.conf and rebuilt the initrd image, then reboot. All worked fine. But Whitebox is crap and was giving me probs and also want everything standardized on CentOS!
Thanks!

The option name changed in 2.6 kernels. It's now called "scsi_luns". You'd need to put it into /etc/modprobe.conf these days too (modules.conf doesn't exist anymore).
Thanks! but when I used "scsi_luns" it booted with an error saying unrecognized option. I changed it to "max_luns" and works fine now. Thanks for pointing me in the right direction though!
