I'm working in a large enviroment where hundreds of datastores will be changed due to SAN units being replaced. After all VMs have been migrated to new datastores on the new SAN, is there any harm in just removing the zoning on the SAN switcheds and doing a rescan? These are HPDL380 series servers attached to EMC vmax.
I'm familiar with the KB below which talks about dismounting and detaching but I'm wondering if it' even necessary in my situation. We regularly change masking views on the storage for the purpose of migrating from one cluster to another and after, when the masking views are removed, there's no impact to the servers.
