Hello Everyone,
I am completely new to EMC Isilon and have only started learning about it this month.
I have a lab environment with EMC Isilon x200 OneFS 7.1.1 and 8.0.0.6.
Searching for FRU replacement guides for the v7.1.1 has been a complete waste of time.
But then I noticed that the FRU replacement guide for V8.0.0.6 includes commands for lesser
versions for achieving the same task.
I would like to go through both manuals and be able to tell the differences in the hardware
replacement procedures and as such, would appreciate your help with the following;

Questions:
1. Are there FRU replacement guides specifically for v7.1.1? If yes, please direct me on how
    to access these information.

2. Is it compulsory to install an FRU package for CTO nodes in OneFS v8.0.0.6 before hardware    replacement,     expecially when there is no more support?

3. With regards to drives replacement in v8.0.0.6, is it compulsory to update firmware after replacement?
    If no, what effect would not updating drive firmware have on nodes in a production environment?

4. When replacing a node, is the license tranferable to the new node in the cluster?
    If there are documents that explains this, please direct me.

 

Thank you!
