UNSOLVED
Adding Second Storage Processor
I am upgrading an AX4 that has Navi Express installed. I have the document to go from single-sp to Dual-sp. I understand the method but have a few questions as I have never done this before.
First off the san has data on it. This will be done after hours with the servers connected turned off. Will data that resides on the SAN be removed? The document says to unititalize the AX.
Question: Is this just removing the networking information for management or will it remove storaed data on the disks and iSCSI addresses?
My second question is just kind of general for those who have done this.
Question: Any gotchas? Is the 5 to 6 hour estimated time in the document accurate?
Thank you everyone in advance for your insight.

for the first question: it only removes the network information.....
for the second question: it depends on the configuration of the array and how many features (enablers) are installed. The more features the more reboots will be required for the new SP. But if your hosts are off-line, I expect this to take no more than 3 hours.
But please be patient; don't reseat the new SP during the process..... its green light will blink throughout the reboots. When it goes solid green for more than 10 minutes, then the process is completed and you should be able to browse to your new SP and re-initialize (navisphere login information) the array.

Just wanted to pass along this information. The 5-6 hour estimate for an AX4 is very conservative. It only took a few hours.
When I preformed the operation only the network IPs on the management interface were removed. The data and iSCSI connections remained.
