A: No. Installing or removing a license does not touch your existing logical drives or data. It only changes available features upon reboot.
(via purchase or old asset), install it using the ssacli method and your server will run RAID 5 perfectly for another 5 years as a backup or auxiliary server. hp smart array p420i license key
This article dives deep into everything you need to know about the —what it is, why you need it, where to find it, and the best strategies for managing it in 2025 and beyond. What is the HP Smart Array P420i? Before discussing licenses, it is crucial to understand the hardware. The P420i is an integrated (hence the "i" suffix) SAS RAID controller. Unlike its add-on card cousin (P420), the P420i is built into the motherboard. (via purchase or old asset), install it using

You cannot hack it.
A: If you are using RAID 0 or 1, the error is cosmetic. Your server will work fine. If you try to use RAID 5 without a license, the array will enter a failed state after 30 days.
