What is ibmSystemPhysicalMemoryIsActive?
This value reports whether a given physical memory module is currently active in the system, returning 1 if active and 0 if not. Admins check this to identify memory modules the operating system has recognized but disabled or taken offline, which could explain reduced usable RAM. For example, a DIMM showing ibmSystemPhysicalMemoryIsActive as 0 after a firmware update might indicate it was deconfigured due to a detected fault.
