I have a lock contention on my (E6900) solaris-9 server, that brought my server to kneese. Found that "dmp_rel_exclusive_lock" of VxVM was the one that consumes all the server CPU resources.
Since I did not know the right solution to tackle this issue, I rebooting server. And the lock contention was cleared out.
By the way, I used lockstat to capture the system locks.
Anyone encountered such locking problem in VxVM 5.0 MP1? Any thougths...
