I have an Avaya Call Management System that runs on Solaris 10 8/11 s10x_u10wos_17b X86. I have been trying to prepare a USB storage device on the system so that I can backup my CMS data. I have tried several different devices, including SanDisk Cruzer 4G stick, SanDisk Cruzer Ultra 16G stick, Gorilla Drive 32G stick, and a Seagate 500G SATA in a USB external enclosure, all unsuccessfully. The system recognizes all of the devices, and I can create UNIX partitions on all of them using FDISK. But when I try to create the file system using the newfs command, I get the error:

"Can not determine partition size: Invalid argument"

Here's the steps I have performed, in detail...

1. # rmformat -l
Looking for devices...
1. Logical Node: /dev/rdsk/c1t4d0p0
Physical Node: /pci@0,0/pci108e,4849@1f,2/cdrom@4,0
Connected Device: TEAC DV-W28SS-V 1.0B
Device Type: DVD Reader/Writer
2. Logical Node: /dev/rdsk/c3t0d0p0
Physical Node: /pci@0,0/pci108e,4849@1d,7/storage@5/disk@0,0
Connected Device: ST950042 0AS 0002
Device Type: Removable

# fdisk /dev/rdsk/c3t0d0p0
Total disk size is 60801 cylinders

SELECT ONE OF THE FOLLOWING:
1. Create a partition
2. Specify the active partition
3. Delete a partition
4. Change between Solaris and Solaris2 Partition IDs
5. Exit (update disk configuration and exit)
6. Cancel (exit without updating disk configuration) Enter Selection: 5


# newfs /dev/rdsk/c3t0d0p0

Can anyone tell me what I'm doing wrong?
