Setting fan speed on HB-1235

[MasterTacoChief]

Figure it's a long shot, but has anyone had any luck setting the fan speed on the HB-1235 using sg_ses? Unlike most people on here, I actually want to speed the fans up since it's not in the coolest environment. I can see the SES entries, but it doesn't seem to respond to any of the requests as outlined in the standard spec. The status page seems to follow the standard, but for some reason the request page doesn't do anything.

The shelf appears to have four fan entries, all look like this:

Code:

root@nas2:~ # sg_ses --index=coo,0 ses0
  XYRATEX   HB-1235-E6EBD	 2005
  Primary enclosure logical identifier (hex): 50050cc10a106637
Enclosure Status diagnostic page:
  INVOP=0, INFO=0, NON-CRIT=0, CRIT=0, UNRECOV=0
  generation code: 0x0
  status descriptor list
	  Element 0 descriptor:
		Predicted failure=0, Disabled=0, Swap=0, status: OK
		Ident=0, Do not remove=0, Hot swap=1, Fail=0, Requested on=0
		Off=0, Actual speed=3300 rpm, Fan at lowest speed

Requested on=0 seems strange, so I tried to set that:

Code:

root@nas2:~ # sg_ses --index=coo,0 --set=on ses0
root@nas2:~ # sg_ses --index=coo,0 --get=on ses0
0

Also, setting the fan speed (supposed to be the lowest three bits of address 3) does nothing.

Code:

root@nas2:~ # sg_ses --index=coo,0 --set=3:2:3=7 ses0
root@nas2:~ # sg_ses --index=coo,0 --get=3:2:3 ses0
1

Anyone using one of these with different results? Or anyone have a manual for this thing with some config details that would shed some light on setting the fan speed?

Thanks.

I can only confirm that the commands you are trying to use are correct. I use the same commands to control my backplane and the fans listen to it well.

I checked some documentations of your backplane and it seems the fans are controlled by the backplane firmware. My guess is that maybe the manufacturer disabled SES control intentionally.

What can be done, can also be undone... let's figure this one out.

I just ordered one of these. Did you get it working?

No... I sold it, too frustrating. Very well built box, but lacking fan control drove me to sell. I bought a DL380e G8 which is only 60dBa... tollerable even in close proximity.
