Assuming system disabled the auto mount option.
How to check auto Mount is disable or not:

maintenance    11:55:11 svc:/system/filesystem/volfs:default

****************** if it is in maintenance mode*****************

cat /var/svc/log/system-filesystem-volfs:default.log 

Manual method... 

root@PHM1SVEWBSCSDB# svcadm clear volfs 

root@PHM1SVEWBSCSDB #svcs volfs 

STATE STIME FMRI offline* 22:17:30 svc:/system/filesystem/volfs:default 

root@PHM1SVEWBSCSDB # svcadm enable -s volfs 

root@PHM1SVEWBSCSDB #svcs volfs 

STATE STIME FMRI online 22:17:42 svc:/system/filesystem/volfs:default 

**********************************************************************
if it is disabled, enable it for enable auto-mounting option.

# svcadm enable volfs

If the  usb flash is recognize by the system it will be mount and you  can see the

For mount USB HDD
set the default solaris partition up (pick the default prompt here)
# fdisk /dev/rdsk/[device_name]
get the number of sectors in the disk (look for the 'Sector Count' column)
# prtvtoc /dev/rdsk/[device_name]
make a ufs filesystem on the device
# newfs -v -s [sector_count] /dev/rdsk/[device_name]
make a mountpoint
# mkdir /usbdrive
mount the formatted disk (note that we no longer use the raw disk here (rdisk))
# mount /dev/dsk/[device_name] /usbdrive
 To find under what names file systems are mounted:  use the
root@PHM1SVEWBSCSDB #df -k
