Title:
udev ata_id environment keys not imported for sata hdd
Status in sg3-utils package in Ubuntu:
Expired
Status in systemd package in Ubuntu:
Expired
Bug description:
Hello,
While debugging why `pm-utils` hdparam udev rules were not picked up by my
SATA HDD, I found that it depends on the presence of the
`ID_ATA_FEATURE_SET_APM`
env key to set the drive advanced power management. This key is returned by
`ata_id` correctly but, among other values, they are never imported as
environment keys by udev.
They seem to be imported in `/lib/udev/rules.d/60-persistent-
storage.rules`
# ATA
KERNEL=="sd*[!0-9]|sr*", ENV{ID_SERIAL}!="?*", SUBSYSTEMS=="scsi", \
ATTRS{vendor}=="ATA", IMPORT{program}="ata_id --export $devnode"
But this rule is not applied since `sg3_utils` already set an
`ID_SERIAL` in
https://github.com/hreinecke/sg3_utils/blob/master/scripts/55-scsi-
sg3_id.rules#L100C61-L100C61
I workaround this by introducing a new rule that imports the `ata_id` output
on that
device, without the ID_SERIAL condition, which makes hdparm to detect APM
correctly.
So, regardless of how hdparm is detecting APM capabilities, I'm not sure the
current
behavior is expected or not. I would expect that the `ata_id` env properties
are
always imported if the device has `ID_ATA=1`
