Manually Enabled TLER Setting Being Disabled After Hibernation

[Ukabuke]

I recently set up a DS418 NAS populated with 2 WD Ultrastar 8TB drives for volume 1 (sda + sdb), and 2 WD RED 3TB drives for volume 2 (sdc + sdd).

I have somewhat followed the instructions here to enable TLER for the 2 Ultrastar drives, since TLER is NOT enabled by default for these drive, but they are capable of it

I have used the following modified entries in the /etc/rc.local startup script:

/usr/bin/smartctl -d sat -l scterc,70,70 -i /dev/sda
/usr/bin/smartctl -d sat -l scterc,70,70 -i /dev/sdb

SCT Error Recovery control starts and shows enabled, until the drives go into hibernation mode. Once they wake up from hibernation, it's disabled.

Any ideas? Thanks in advance!

Wow. That formatting was unexpected (and barely readable in dark mode @SynoMan )

That’s what I’m doing with my rc.local script. I just hard coded the drives identified since sda and sdb are the only drives that need it turned on. My RED drives are already enabled.

My rc.local file looks like this:
#!/bin/sh
/usr/bin/smartctl -d sat -l scterc,70,70 -i /dev/sda
/usr/bin/smartctl -d sat -l scterc,70,70 -i /dev/sdb
exit 0

As I mentioned, it turns on OK, but gets disabled after the drives hibernate. This is the strange issue.
