steps need to be done when doing SAN MIGRATION online

I'll assume that the reconfiguration you are performing might be (but not limited to) any of the following:

• Removing or adding HBAs
  
• Adding, removing, or changing storage system logical devices
  
• Changing the cabling routes between HBAs and storage system ports
  
• Adding or removing storage system interfaces
  

The "PowerPath for * Installation and Administration Guide" has a section that covers this and is appropriately named "Reconfiguring PowerPath devices online".  You can find both the Solaris and Linux Guides on PowerLink as follows:

Home > Support > Technical Documentation and Advisories > Software ~ P-R ~ Documentation > PowerPath Family > PowerPath > Installation/Configuration

Hello,

  The host connectivity Guide for each OS may have some helpful information as well.

Available on powerlink at:

Home > Support > Technical Documentation and Advisories > Host Connectivity/HBAs > Installation/Configuration

Hope this helps,
