These are the steps I took to add an external USB disk to my x86 Solaris station, partition it and put ufs filesystems on it.
- Tell the removable volume manager to leave USB disks alone
- edit /etc/vold.conf
# commented the following line
# use rmdisk drive /dev/rdsk/c*s2 dev_rmdisk.so rmdisk%d
- Activate the configuration change
# svcadm refresh volfs
- attach the USB drive
- lookup the USB device name
# rmformat
Looking for devices...
1. Volmgt Node: /vol/dev/aliases/cdrom0
Logical Node: /dev/rdsk/c0t0d0s2
Physical Node: /pci@0,0/pci-ide@6/ide@0/sd@0,0
Connected Device: LITE-ON DVD SOHD-16P9S F3S2
Device Type: DVD Reader
2. Logical Node: /dev/rdsk/c2t0d0p0
Physical Node: /pci@0,0/pci108e,5347@2,1/storage@4/disk@0,0
Connected Device: ST316021 2A 0000
Device Type: Removable
- Solaris x86: create a Solaris fdisk partition on the device
# fdisk -B /dev/rdsk/c2t0d0p0
- Partition the drive. The format expert option is needed for the drive to show up:
# format -e
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1t0d0 <DEFAULT cyl 9726 alt 2 hd 255 sec 63>
/pci@0,0/pci108e,5347@7/disk@0,0
1 . c2t0d0 <DEFAULT cyl 19454 alt 2 hd 255 sec 63>
/pci@0,0/pci108e,5347@2,1/storage@4/disk@0,0
Specify disk (enter its number): 1
...
- Now partition the drive.
- Solaris x86: keep clear of cylinder0. It is in slice 8 and reserved for the VTOC and booting (grub).
- create a file system on your partition(s) (I ignored the warning)
# newfs /dev/rdsk/c2t0d0s0
Warning: setting rpm to 60
newfs: construct a new file system /dev/rdsk/c2t0d0s0: (y/n)? y
...
- Add the file system to /etc/vfstab
...
/dev/dsk/c2t0d0s0 /dev/rdsk/c2t0d0s0 / stuff ufs 1 yes
- mount the file system
# mount /stuff
