I have a blank T5120 server without any optical drive onto which I want to install Solaris 11.3. I downloaded the sol-11_3-text-sparc.usb installer. The docs tell me to use a tool named usbcopy to fill a stick.
I don't have this tool since I don't have a Solaris box yet. But I do have FreeBSD running, which reports
$ file sol-11_3-text-sparc.usb
sol-11_3-text-sparc.usb: Unix Fast File system [v1] (big-endian),
last mounted on /export/dc/s11/s11_3sru01/builds/text/build_data/tmp/tmpcScvPf-,
last written at Tue Oct 6 16:15:52 2015, clean flag 1,
number of blocks 1014784, number of data blocks 953823,
number of cylinder groups 26, block size 8192, fragment size 1024,
minimum percentage of free blocks 6, rotational delay 0ms,
disk rotational speed 3rps, TIME optimization
Can I simply
dd if=sol-11_3-text-sparc.usb of=/dev/da3 # Where da3 would be the whole stick
or does usbcopy provide some extra processing?
Answer
usbcopy used to be required, but since 11.2 you can just use dd as you've described. The only thing usbcopy adds is verifying the copy as it goes.
