After update (i think, but may be something else) from Solaris 11.1 to 11.3, dladm and dlstat commands was broken. Invoking dladm or dlstat gives error:
$ dladm
dladm: could not open /dev/dld: operation failed
How to fix this?

Check the service status:
# svcs -av
svcs: Could not bind to repository server: repository server unavailable. Exiting.
CAUSE: Checking the services status shows the the repository daemon was not up:
SOL: Send a SIGTERM to svc.startd. That will cause svc.startd to restart and spawn a new svc.configd daemon that remains under control of svc.startd
# /lib/svc/bin/svc.configd
to refresh the repository

I'm impressed. There were lots of
svc.startds so I did akill -TERMon the one with the-sand it also had the smallest PID. Nov 10, 2023 at 15:52

You should see output likedld 48. What's the output fromgrep dld /etc/minor_perm? You should seedld: * 0666 root sys. If those are correct, runtruss -o /path/to/some/output/file dladm, findwrite(2,in the output file - which is where it emits the "operation failed" error message and see what it's trying to do. The OpenSolaris source code can be found at src.illumos.org/source/xref/illumos-gate/usr/src/cmd/dladm/… and src.illumos.org/source/xref/illumos-gate/usr/src/lib/libdladm/…show-linkas the Solaris 11 code does), the only way to get thedladm: could not open /dev/dld: operation failederror message is for the call toopen( "/dev/dld" ... );to fail with an unexpectederrno. The Solaris 11 code likely behaves the same, which means something unexpected is going on. Hence thetrusscommand to find out what that unexpectederrnoactually is.
