Dear all,
at our SLES11 server there is an iscsi tape roboter from OVERLAND
attached.
We learnt to use udev rules in order to fix the device name for the
media changer
/dev/sgN where N is altering after each reboot.
Here is the udevinfo output of our tape changer:
#udevinfo -a -p $(udevinfo -q path -n /dev/sg5)
looking at device
'/devices/platform/host4/session1/target4:0:0/4:0:0:2/scsi_generic/
sg5':
KERNEL=="sg5"
SUBSYSTEM=="scsi_generic"
DRIVER==""
looking at parent device
'/devices/platform/host4/session1/target4:0:0/4:0:0:2':
KERNELS=="4:0:0:2"
SUBSYSTEMS=="scsi"
DRIVERS==""
ATTRS{device_blocked}=="0"
ATTRS{type}=="8"
ATTRS{scsi_level}=="6"
ATTRS{vendor}=="OVERLAND"
ATTRS{model}=="NEO Series "
ATTRS{rev}=="0510"
ATTRS{tgps}=="1"
ATTRS{state}=="running"
ATTRS{timeout}=="0"
ATTRS{iocounterbits}=="32"
ATTRS{iorequest_cnt}=="0xe"
ATTRS{iodone_cnt}=="0xe"
ATTRS{ioerr_cnt}=="0x3"
ATTRS{modalias}=="scsi:t-0x08"
ATTRS{evt_media_change}=="0"
ATTRS{queue_depth}=="32"
ATTRS{queue_type}=="none"
Therefore we built a new rule called 100-local.rules in /etc/udev/
rules.d with
this line:
KERNEL=="sg*", SUBSYSTEMS=="scsi", ATTRS{rev}=="0510", SYMLINK
+="loader0"
After running /etc/init.d/boot.udev restart we would expect to see
/dev/loader0. But it does'nt exist, why?
THX for any hint advice,
Rainer
