Sun has an "official" guide to using removable media, with the new USB support in Solaris 9 04/04, at: Using USB storage devices with Solaris 9
Unfortunately, there are a few errors here and there, it seems.
First of all, it suggests going to /dev/rdsk, and doing
ls -l c*0 | grep usbThat doenst (always?) work, because the device might not HAVE "usb" in the name. For example,
/devices/pci@0,0/pci1028,155@1d,7/storage@7/disk@0,0:aSo, you're better off just looking at the full output, and judging for yourself which one you need to use. (Probably the one with "storage" in it, if you're using a flashram stick).
Secondly, the page suggests,
mkfs -F pcfs -o nofdisk,size=[size] raw-deviceTrouble is, that doesnt work for cXXXXs0, even after killing vold. What appears to be needed on x86, at least, is to use the p0 device. Example that I'm trying out, for a 256meg flash stick:
mkfs -F pcfs -o nofdisk,size=262144 /dev/dsk/c2t0d0p0But.. that still might not work!!
So, worst case, if you want to deal with a PCFS memory stick, on solx86, you have to be root, and then manually do stuff like
mount -F pcfs /dev/dsk/c2t0d0p0:c /mntNote the use of both "p0", and ":c" (to denote dos "C drive" style access) Yes, neither :a nor :b will work.
And on top of ALL THAT.... The support for it seems unreliable. It doesnt always work.
ALTERNATIVELY, you can try killing vold, inserting the stick, then starting vold. that sometimes works better, and automatically mounts the media under /rmdisk/rmdisk0. But even then, writes to it may be unreliable.
Final note: in theory, the user interface would involve the command "volrmmount". But it doesnt seem to work, just like vold "should" detect an insert, but doesnt. Kill-and-restart-vold seems to be the best way, even in sol10 x86
Summary: on x86, your life becomes much easier by using using c2t0d0p1, to access "1st fdisk partition". In comparison, on sparc, you still have to use the odd colon notation mentioned above: c2t0d0s2:c
The good news is, there is at least an "fdisk" command on sparc, and it actually works!... you need to use it on slice 2, no ":c".
A convenient shortcut to see if an inserted device is recognized by the kernel, is to run the "rmformat" command. It will give you a list of all "removable media" devices. (USB inserts, and also cdrom type devices) For example:
$ rmformat Looking for devices... 1. Logical Node: /dev/rdsk/c0t2d0s2 Physical Node: /pci@1e,600000/ide@d/sd@2,0 Connected Device: TOSHIBA ODD-DVD SD-R1512 1010 Device Type: DVD Reader 2.
