In this video, you can get a detail explanation of the device login process on SAN switch. Three device login Steps are FLOGI, PLOGI, and PRLI.
What is Device Login In SAN Switch?
Device Login is a series of process which happens when a new node or devices is connected to a Fabric. Once Device Login Process Completes then a device can communicate with other devices in the same fabric.
Its Involves Three Steps involves FLOGI PLOGI and PRLI.
What is FLOGI Process in SAN switch network
FLOGI Process happens when a new device is connected to switch or fabric for the first time. Once the device is power the device sends its first frame to the switch where it is connected. The first frame contains some information like WWPN and buffers to buffer credits (B2B credits).
The switch reads this information and then assigns a 24 bit Unique ID address to the device. This unique ID called FCID. The switch uses this FCID to identify the end device connected to it in SAN network. Then the end device also confirms to the switch that it received FCID.
What is PLOGI SAN Switch Network?
Port initialization in Plogi Process
PLOGI Process has two port initialization and registration in Name Server. During port initialization information like port type and port, speed is exchanged between end device or host and SAN switch. SAN switch uses this information and negotiates with the host. During the negotiation, SAN switch will come to know whether the end device is a server or storage by referencing the port type.
What is Name Server In SAN Switch Network
Each fabric is a SAN switch network that maintains a name server. This name server contains the information of every device connected to the SAN Fabric. Two devices in the SAN switch network can communicate only if both of them are Name servers.

I tried to understand this Flogi, Plogi thing in quite a few places(books, video's), but none made it this clear. Your video was bang on, simple, easy to understand and the explanation of the entire fabric login procedure. Thanks a lot for this...

[@pratibhaprasad8675]

Can you please do a demo video of NPIV, switch name server details.

[@azizkheriwala9409]

[@saNasTech]

I have faced this issue many time in my case rezoning or just removal of host alias from zone then adding back works

Hello sir i have two SAN switch in one switch in building A and other switch in building B in building A switch connected with two server and one storage and building B switch connected to two server i want to communicate building B servers to building A storage how to configure this .

[@saNasTech]

You can configure this using LSAN(cisco) or IVR (Cisco MDS). You also need to contact support for the exact steps.
