The original question is at the bottom of this email:

The following are suggestions that were provided:

* For Solaris 10 they could use the fmadm utility. This utility is part 
of Solaris 10. No download needed.

* to read all the mem you can do  wc -c /dev/mem as root

* SUNWvts or drop down to OBP and set the diag switch to max

* cddiag tool - url here:

Thank you for all of the input.

I have a Sun v490 server that generated a few soft ram errors over the

My boss asked me if there was any way to test a memory stick from the OS
level, vs dropping down to the OBP, and coming back up with the max-diag
-level switch set.

Prior to this post, I did review the archives and do some Yahoo
searches.  I came up with a couple of utilities, primarily memconf and
SunVTS.  Memconf provides nice detail about your system ram, but does
not do any testing.  the Sun SunVTS appears that it will test all ram,
but I don't feel that from reading the documentation, that I can
exclusively test only a specific ram stick (i.e. memory module slot
J8203) using SunVTS.

I feel that probably the right answer is just to bring the system down
to the OBP and test there, but am curious if anyone else has other tools
for this task.

Thank for any replies, I will summarize.
