Cannot manage APM Level on WDC WD100EMAZ

by |Published

I was looking into configuring some sleep schedules for my server disks, but it looks like I cannot change any settings on my drives. I am looking for some help on this because I am pretty inexperienced with configuring hdparm settings.

Error Message

sudo hdparm -B 127 /dev/sda

/dev/sda:
 setting Advanced Power Management level to 0x7f (127)

Hardware & OS:

  • Proxmox 7.4-17
  • Drives connected to DELL HBA330 J7TNV 12Gb/s 3rd Gen LSI SAS3008 HBA 9300 9311-8i
  • WDC WD100EMAZ-00WJTA0 Drive model
  • Disks are part of a Raid Z2 array Configured with the Proxmox host.

Goal

I would like to successfully configure these drives to sleep after 10 minutes of inactivity with:

 hdparm -S 120 /dev/sda 
hdparm -S 120 /dev/sdb 
hdparm -S 120 /dev/sdc 
hdparm -S 120 /dev/sdf 
hdparm -S 120 /dev/sdg 
hdparm -S 120 /dev/sdh

With the understanding that APM must be less than 128 to all for spindown configuration.
