Drives not waking up

[Craigp23]

Hello :)

Running hd-idle with defaults on an OMV7/Debian system with several Exos SAS drives connected via an LSI HBA (IT mode) card.

hd-idle is successfully spinning down the disks after 10 minutes or so but the disks aren't waking up.

The OS gives an I/O error (or read/only error) when I run fdisk, etc to attempt to wake them up.

If the system is rebooted all okay... for 10 minutes ;o)

TIA

Hi @Craigp23
I can only suggest to use a different -c command_type option.
Please check the documentation here.

Thanks, I'll try & post back🤞

I assumed the default (scsi) was the right method for this setup.

Edit : Thanks for the link to the documentation. I noticed this about the -p option :

"The default value of 0 works fine for disks accessible via the SCSI layer (USB, IEEE1394, ...), but it will NOT work as intended with real SCSI / SAS disks. A stopped SAS disk will not start up automatically on access, but requires a startup command for reactivation. Useful values for SAS disks are 2 for idle and 3 for standby."

I'll try setting -p to 2 or 3...
