About: Persistent binding

Host-based zoning can include WWN or LUN masking, and is typically known as “persistent binding.” In storage networking, ”persistent binding” is an option of zoning. Host-based zoning is usually referred to as persistent binding or LUN, and is perhaps the least implemented form of zoning. Because it requires the host configuration to be correct in order to avoid zoning conflicts, this form of zoning creates a greater opportunity for administrative errors and conflicting access to targets. Moreover, zoning interfaces vary among different host operating systems and HBA's — increasing the possibility for administrative errors. If a host is not configured with the zoning software, it can access all devices in the fabric and create an even higher probability of data corruption. Host-based zonin
