Which user does an Implementation Engineer use when preparing for the Purity upgrade to complete...

When performing a Hardware Non-Disruptive Upgrade (HWNDU) or preparing for a Purity software upgrade, the Implementation Engineer must log in with a user account that has full administrative privileges to execute upgrade commands, run health checks, and manage the array state.

Thepureuseraccount is the standard administrative superuser for the FlashArray. It is used for all day-to-day administration and maintenance tasks, including initiating upgrades via the CLI (pureinstall or pureupdate commands) and verifying system health (purearray health, pureadm list). The puresetup account is strictly for initial array initialization (setting IPs and array name) and is disabled or restricted once the array is up and running. pureinstall is a command, not a user account. Therefore, pureuser is the correct authenticated session required to manage the upgrade process.
