Actually, I have my msl 2024 1760 SAS tape library attaching to my HP DL 180 G6 thru Smart Array P212. I can successfully use this tape library with my window 2008 ad backup exec 2010. While from my freeBSD 8.0, 8.0 p3 or even 8.1 RC2, I don't even see the /dev/ch0 device link whereby I can see this device using the camcontrol devlist -v. My question is: - 1. Is there any way I can manually create/link the /dev/ch0 device driver ? 2. How can I achieve 1 if it is possible. 3. Having learnt that exposing disk mirror controller should be considered as danger, may I have more information and background information about that ? What specific problem will I encounter for that ? Pls find below the configuration details which is related to the tape library:- 1: 2: 3: 4: 5: 6: 7: 8: 9: server# dmesg | grep ciss ciss0: port 0xd800-0xd8ff mem 0xfb800000-0xfbbfffff,0xfbdff000-0xfbdfffff irq 24 at device 0.0 on pci6 ciss0: PERFORMANT Transport ciss0: [ITHREAD] ciss1: port 0xc800-0xc8ff mem 0xfb400000-0xfb7fffff,0xfb3ff000-0xfb3fffff irq 32 at device 0.0 on pci4 ciss1: PERFORMANT Transport ciss1: [ITHREAD] sa0 at ciss0 bus 32 scbus1 target 6 lun 0 da0 at ciss1 bus 0 scbus2 target 0 lun 0 1: 2: 3: 4: 5: 6: 7: 8: 9: server# camcontrol devlist -v scbus0 on ciss0 bus 0: scbus1 on ciss0 bus 32: at scbus1 target 6 lun 0 (sa0,pass0) scbus2 on ciss1 bus 0: at scbus2 target 0 lun 0 (da0,pass1) scbus3 on ciss1 bus 32: scbus-1 on xpt0 bus 0: <> at scbus-1 target -1 lun -1 (xpt0) 1: 2: 3: 4: server# camcontrol reportluns 1:6 2 LUNs found 0 1 1: 2: 3: 4: 5: 6: 7: 8: 9: 10: 11: 12: 13: 14: 15: 16: 17: 18: 19: 20: 21: 22: server# ls /dev/ acd0 da0s1e led sa0.2 ttyvb acpi da0s1f log sa0.3 ttyvc ata dcons mdctl sa0.ctl ttyvd atkbd0 devctl mem stderr ttyve audit devstat nfslock stdin ttyvf bpf dgdb nsa0 stdout ufsid bpf0 esa0 nsa0.0 sysmouse ugen0.1 bpsm0 esa0.0 nsa0.1 ttyu0 ugen1.1 ciss0 esa0.1 nsa0.2 ttyu0.init ugen2.1 ciss1 esa0.2 nsa0.3 ttyu0.lock ugen3.1 console esa0.3 null ttyv0 ugen3.2 consolectl fd pass0 ttyv1 ugen4.1 ctty fido pass1 ttyv2 ugen5.1 cuau0 geom.ctl pci ttyv3 ukbd0 cuau0.init io psm0 ttyv4 ums0 cuau0.lock kbd0 ptmx ttyv5 urandom da0 kbd1 pts ttyv6 usb da0s1 kbd2 random ttyv7 usbctl da0s1a kbdmux0 sa0 ttyv8 xpt0 da0s1b klog sa0.0 ttyv9 zero da0s1d kmem sa0.1 ttyva
