Bug description:
This is a request to add the following upstream commit to both Ubuntu
16.04.1 and 16.04.2:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/scsi/ses.c?id=9373eba6cfae48911b977d14323032cd5d161aae
Without this patch, the symlink in sysfs which binds a SAS device to
an enclosure slot does not get created. This makes disk hotplug near
impossible on large JBOD disk drawers.
You should be able to do:
ls /sys/block/sdb/device/ | grep enclosure
and see something like:
enclosure_device:1
If you cd to this directory, you can then access the SES controls for
that slot to flash the LED to assist in locating the disk to replace a
failed disk.
Currently with 16.04.1 and 16.04.2, these symlinks are not getting
created.
