An important thing to know in this context is that you can't create a pool on removable media devices, i.e. the ones whose storage media can be removed. DVD drives and flash readers are removable media, hard disks are not. So you'll need one or more USB hard disks. Most USB hard disks and IDE-to-USB enclosures should work. Thumb drives are not likely to work. In this experiment I'm using two USB 2.0 disks: a 20GB LaCie and a 40GB IOGEAR.
For the reasons that are beyond this blog entry, the Solaris USB driver presents any USB storage device as removable media. A simple command to list removable and non-removable disks is format(1M). Quoting the man page:
Removable media devices are listed only when users execute
format in expert mode (option -e).
Run format with and without -e and notice the difference:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1d0
/pci@0,0/pci-ide@8/ide@0/cmdk@0,0
Specify disk (enter its number): ^C
# format -e
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1d0
/pci@0,0/pci-ide@8/ide@0/cmdk@0,0
1. c4t0d0
/pci@0,0/pci1297,a550@2,2/storage@6/disk@0,0
2. c5t0d0
/pci@0,0/pci1297,a550@2,2/storage@5/disk@0,0
Specify disk (enter its number): ^C
c4t0d0 and c5t0d0 are USB disks.
What we're going to do is tell the USB driver not to treat hard disks as removable media. This can be done by appending the following line to /kernel/drv/scsa2usb.conf file:
attribute-override-list =
"vid=* removable=false";
Reboot for these changes to take effect. Now all your USB hard disks are going to be treated as fixed (but you can still hotplug them). You can verify that by running format without -e option - if it still doesn't list your USB disk, most likely it's one of the rare samples that pretends to be removable media and that's a hack for another day.
Now you can use these disks just like any fixed disk:
