I just came across the following on the VMTN forum which is a very useful command in my opinion. When metadata changes for a LUN, that LUN is being locked by a host. Sometime the lock isn’t released, which can cause weird situations. In this case you would want to know which host is locking the LUN, especially when you’ve got over a dozen hosts. Rubeck posted a reply on Vliegenmeppers question on the forum:

esxcfg-info -s | grep -i -B 12 pending

Thanks guys,
