You have a typo: scsi_genric instead of scsi_generic.
Don't know if that is the reason.
SYMLINK:="sg8" -> SYMLINK+="sg8"
Could you try putting the link aside via SYMLINK+="mytape/mydevice".
Is this feasible for you having it in a sub directory?

You have a typo: scsi_genric instead of scsi_generic.
Don't know if that is the reason.

[CentOS] udev on CEntOS7 - can't get a match, looking for tips...
The mtx binary requires my tape library to be assigned a sg# driver, but
the kernel periodically renumbers the sg devices. Normally, we would
write a udev rule to manually assign a persistent name, but it looks
like things have changed as I can't seem to get a match on CEntOS7. I'd
appreciate any feedback or pointers to help me get my rule working. My
two attempts are below.
cat /etc/udev/rules.d/90-local.rules
KERNEL=="sg[0-9]*", SUBSYSTEM=="scsi_generic", \
ENV{ID_SERIAL}=="1QUANTUM_D0H0112430_LLA", SYMLINK+="sg8"
SUBSYSTEM=="scsi", SUBSYSTEMS=="scsi_genric", \
ATTRS{model}=="Scalar i40-i80 ", SYMLINK:="sg8"
Neither rule above generates a match with udev, so I still have
something wrong. Right now the assignment is sg7 (but it's had other
names in the past.
