Description of problem: Currently the chapter 8.8.5 of the RHEV Administration Guide says that it's enough to remove a storage domain from RHEV Administrator Portal to get rid of it. However, due to bz#880738 and bz#1134144 it is required to remove paths from hosts manually before unzoning the LUNs on storage side. Failure to do so causes major stability issues in the environment. This affects all versions from 3.0 through 3.5 so I request adding a warning/note/link to KB on how to do this to avoid issues of RHEV. Version-Release number of selected component (if applicable): https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/html/Administration_Guide/sect-Storage_Tasks.html#idp33428112 How reproducible: Always Steps to Reproduce: 1. environment with several FC storage domains 2. go by the current doc to remove a storage domain 3. after completing the steps, unzone the LUN immediately Actual results: All datacenters unstable, SPM role flipping between hosts, VM migration storms caused by timeouts during LVM commands Expected results: Users are warned not to unzone LUNs before they're detached from hosts Additional info: https://access.redhat.com/solutions/129983
