Symptoms

Sun Fire 12K/15K/E20K/E25K System Controller may encounter unexpected outages due to hung of Solaris, after issueing the data link administration command "dladm" directly on console on System Controller OS once, or at least after some attempts.

These command sets are not really relevant for usage on Starcat System Controllers and for platform management:

 

Changes

The descripted symptoms have been seen only on Sun Fire 12K/15K/E20K/E25K System Controllers with SMS 1.6 on Solaris 10 so far.
The behavior described in this document has been discovered on SCs which have had maintenance and diagnostic actions time before in terms of Solaris kernel issues, and advanced diagnostic methods have been applied (kmem_flags were set in /etc/system).
