Hi all,
(first post, so please cut me some slack :e).
I'm building a new server, third in succession, the two before were also FreeBSD based.
Different to the two servers before this server is the fact that I'm running VMware ESXi 4.1 and I installed a LSI 3081 card. The LSI card is flashed with the IT firmware.
I use the LSI card for two reasons: VMware's PCI Passthrough of the LSI card to the FreeBSD Guest so ZFS can talk to the raw drives instead of suppling the disks via VMware virtual discs to FreeBSD and second reason to be able to hook up more drives than the ICH10 of the motherboard allows to.
All works fine: the LSI 3081 is recognized in FreeBSD, mpt is loaded and the drives are used in a zpool.
I wanted to set up disk spindown as I did on my first two servers with atacontrol, obviously atacontrol is not working here as it is not ATA or AHCI and I need to use camcontrol. However with little success.
Camcontrol is very limited in use: things like
I'm using Samsung F4 204UI drives & FreeBSD 8.2. Is this a (known) limitation of the samsung drives? The LSI card in IT mode? mpt driver handling the IT mode? Or the cam subsubsytem?
I can live with the fact to run the drives 24/7 as there are only 2 for the moment. But in the future, when adding more drives it would be a welcome feature to have up and running.
Thanks,
Huib
(PS. I found the script to "camcontrol stop" all non used drives in a storage pool).

Camcontrol is very limited in use: things like
camcontrol stop/start <dev>
seem to work, however camcontrol identify <dev>
stays very mute, only with the -v flag 2 lines are shown, pass1/pass2. Doing a camcontrol standby/idle <dev>
gives an error:
Code:
