Persitent Binding for HBA Card

Persistent binding : As the name implies persistent binding enables LUNs zoned from a Storage frame will be assigned with a specific target ID. Now next question which might pops up in your mind "Why do we need that"

I don't have any strong answer for it. After googling, got few clarifications which is not much convincing.

Below are the few points which i feel could be a reasonable answer for the above question.

1. In a cluster environment where the same LUN is assigned to multiple machine should be configured with persistent target ID.

2. Its a recommended steps for emulex branded HBA card where drivers software are provided by Emulex and same applies for Q Logic branded card.

Here in this, i would be taking only Emulex and Qlogic card as these cards are the most commonly used card on Solaris Box.

NOTE : You do not need to configure persistent binding for Sun Branded Emulex and Qlogic card.
