Had to do this today, and it took a few tries. Here's what you need to do (incomplete original):
- Insert USB key (ok if machine is alive)
- "iostat -En" will tell you where to find your USB device, e.g.,
c5t0d0 Soft Errors: 2 Hard Errors: 0 Transport Errors: 0 Vendor: USB 2.0 Product: Flash Disk Revision: 1.00 Serial No: Size: 0.13GB <130023424 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 2 Predictive Failure Analysis: 0 --> c5t0d0
- "devfsadm -C"
- "mount -F pcfs /dev/dsk/c1t0d0p0:c /mnt/" -- Make sure you write "dsk" and not "rdsk". Also, you must have trailing slash on the target directory!!
- "umount /mnt" when finished
Amazingly, it actually works. My USB key was formatted FAT32, and I suspect this technique should also work for any other kind of USB storage. If you confirm, let me know.
