Re-imaging an Array
What is the process of re-imaging an array?
When i should use it?
Does it a distruptive process or can be run non-disruptive?
Considerations and Best Practices?

Hi Shawky,
When you say re-image, are you referring to a way of backing up the Cx configuration, in order that you can restore the configuration if it is lost?
In the UK, and within our lab environment, we have been able to backup/restore Cx configurations using the followng two naviseccli command options:
So, this gives us a way of returning a Cx to a pre-defined logical state at the end of a training course.
There is lots to read about these commands in the CLI guide, which discusses reasons why a subsequent duplicate may fail (for example the Cx must be in a clean state for the duplicate (effectively a configuration restore) to work - there must be no RAID groups, LUNs, or user-created Sorage Groups - there are other reasons to read about). This would of course be disruptive.
Before relying on this I would recommend to have a look at the pages in the CLI guide, and hopefully find the luxury of testing this, in order to see if it meets the required needs.
Here is a brief snippet from the CLI guide:
"The arrayconfig -capture command queries the storage system for its
configuration along with I/O port configuration information. When
issued, the command will capture a storage system’s essential
configuration data. The information is formatted and stored on the
client workstation.
This generated file can be used as a template to configure other
storage systems or rebuild the same storage system if the previous
configuration is destroyed. "
Thanks, Richard.

Thanks Richard,
I think you made it very clear.
And the comment you added about the subsequent failure of the command ....
The command should be run in the pure configuration before any modification in the RAID Groups or Storage Groups ....
I think the lab in the next (CLARiiON Integration with VMware) week we are going to have will be a good oppurtiunity to try this commands.
I'll try and give you the feedback ....
Thanks,
Shawky
