In opensolaris 11, the usb is mounted automatically,
I want to use command to mount and umount it, how to do it, I have other FS on my disk Win vfat and linux, can I mount them with command
thanks
bela

Have you tried rmformat ?
Find your USB disk and mount analogical way as it is done below:
Remember that FAT is PCFS. Im not sure how it is with NTFS support under Solaris.

do a df -h

look at output, see how the USB drive is recognized(if it auto mounts it). Then you can unmount it with either the device or location ie:
umount /dev/sda1
or
umount /mnt/usb

you'll have to change the parts after umount according to what you find in df -h
other commands to help determing how the usb drive is recognized are:
dmesg
dmesg | grep sd
or dmesg | grep sb
depending on how many usb drives or sata drives you have


to mount you need to know the filesystem of the drive and a mount point so in this example you have a usb drive with fat32(vfat) FS

mount -t vfat /dev/sda1 /mnt/usb

man mount
for additional help

This is how to mount in Linux.
In Solaris you do it the way czezz indicates:

mount -F pcfs /dev/dsk/c3t0d0s2:c /mnt/usb/

Regs, C

ahh sorry.. haven't used solaris in a long time.

But I'm using Linux and has used your advice. Thank you!
