Dell Powervault 132T Tape Library device node node not creat

Post by teknopow » 2005/05/06 20:20:53

Hello All.

I'm struggling to get CentOS 4 to recognize my Dell Powervault 132T tape changer.
UDEV doesn't create a device node for it.

[root@orion scotty]# dmesg |grep sg
Attached scsi generic sg0 at scsi0, channel 0, id 6, lun 0, type 1
Attached scsi generic sg1 at scsi1, channel 0, id 1, lun 0, type 1
Attached scsi generic sg2 at scsi3, channel 1, id 6, lun 0, type 3
Attached scsi generic sg3 at scsi3, channel 2, id 0, lun 0, type 0

It does recognize the tape device as sg1, but doesnt create a node for the changer (which should be a type 8)

[root@orion scotty]# /usr/sbin/mtx -f /dev/sg1 inquiry
Product Type: Tape Drive
Vendor ID: 'IBM '
Product ID: 'ULTRIUM-TD2 '
Revision: '37RH'
Attached Changer: No

I corrected the typo in the /etc/hotplug/scsi.agent file:

was --> 8) TYPE=changer ; MOUDLE=sg ;;
corrected to --> 8) TYPE=changer ; MODULE=sg ;;

and also added the following line to my /etc/modprobe.conf
options scsi_mod max_luns=255

but it doesnt make any difference.

I read somewhere i should recompile the kernel with 'scan all luns' option enabled but i thought that modifying modprobe.conf would be enough.
Is that correct?
If anybody could point me in the right direction i would be really thankfull.
Cheers and thank in advance
