Locked out dmp_rel_exclusive_lock on Solaris-9 E6900 hardware

Created: 23 Jun 2009 • Updated: 10 Dec 2010 | 1 comment

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...

Thanks,
RR

Not sure about this but can this happening coz of storage....

I reckon one of customer facing this before & in their case Per Lun spindles count was less... which was resolved by array vendor..
