Solaris 10 server. I need to determine if the server is Solaris 10 Update 9 or greater. Can someone interpret the version strings below? What part of those strings identifies the update that has, or has not, been applied to the server?

# uname -a
SunOS rcclab5 5.10 Generic_147440-01 sun4u sparc SUNW,Ultra-80
# cat /etc/release
                   Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC

You cannot "apply an update" with Solaris 10 and older. You either install a Solaris update from scratch or upgrade an existing installation to a newer Solaris update. What you can apply to an existing installation are patches and patches do not change the Solaris update that is installed and reported. –  jlliagre Jul 20 '13 at 20:23

s10s_u10wos_17b the u<#> is the update version. So that is Solaris 10 Update 10.

The line in /etc/release shows it was built in august 2011 and contains s10s_u10wos_17b which reads: Solaris 10 for SPARC (would be s10x for x86), update 10, "wad of stuff" (just means it's not the initial release), 17th build since u10 development started, second respin (b).

Note that this doesn't reflect an update that has been applied or not to the server but the precise version of Solaris that was initially installed on that machine.

Kernel updates can be identified with the kernel patch version, here (147440-01) which is the one delivered with u10. That means it wasn't updated (patched).

Should you have patched the OS, an additional line would have appeared at the end of the file telling what Solaris update the update match.

Generic_147440-01 shows the level of the kernel being used. It IS possible to be running an up-to-date kernel w/o having to do an install of the released update by updating keeping current on all the patches.
