** Description changed: - This is a request to add the following upstream commit to both Ubuntu - 16.04.1 and 16.04.2: + + == SRU Justification == + This bug is resolved by commit 62e62ffd95539b9220894a7900a619e0f3ef4756. + + 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. + + Commit 62e62ffd95 is also needed in Xenial. However, Xenial also needed some + prereq commits, so it's SRU will be sent separately. + + Commit 62e62ffd95 is in mainline as of 4.13-rc1. + + + == Fix == + commit 62e62ffd95539b9220894a7900a619e0f3ef4756 + Author: Maurizio Lombardi <[email protected]> + Date: Tue Jun 27 11:53:27 2017 +0200 + + scsi: ses: do not add a device to an enclosure if + enclosure_add_links() fails. + + == Regression Potential == + This patch was also cc'd and applied to upstream stable, so there is + upstream confidence in it. + + == Test Case == + A test kernel was built with this patch and tested by the original bug reporter. + The bug reporter states the test kernel resolved the bug. + + + + 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.
