[OpenIndiana-discuss] Using large (3-4 TB) USB disks for backups

[Reginald Beardsley]

Tried that.

# cfgadm -x usb_reset usb9/3
Reset the device: /devices/pci at 0,0/pci10de,cb79 at 4,1:3
This operation will suspend activity on the USB device
Continue (yes/no)? yes
cfgadm: Hardware specific failure: Cannot issue devctl to ap_id: /devices/pci at 0,0/pci10de,cb79 at 4,1:3

As it turns out, at least for what I want to do it doesn't seem to matter that I can't get phy_blocksize and ashift set as I want them.  It would be nice to know exactly what the issue is, but for now I think I'm able to do everything I want.  

The larger question is how do I want all this stuff (8 systems on 2 unconnected networks) configured?  I'm sure that will get me into trouble, but that's OK.   I've got a 4 disk N40L that boots from a 4 way rpool mirror and serves a RAIDZ2 pool.  No USB stick or boot drive.  It's quick, uses less than 50 watts under load and can take a 2 disk failure w/o losing data.  Best of all it was under $0.25/GB. It nearly beat me senseless figuring out how to do that, but I think the result was worth the effort.

Next up after the basic configuration is to rebuild my Ultra 20 as an OI build system and see if I can manage to fix minor problems.

Have Fun!

 On Solaris 11, I sometimes find a usb_reset will work
 when the drive won't disconnect or unconfigure.
 # cfgadm -x usb_reset usb9/3
