umcode_latest Command

Purpose

Identifies system resources with firmware or microcode that can be updated from a specified source of image files.

Syntax

umcode_latest [-s source] [-l] [-A] | [-a[-q][-r]| -i] | -h

Description

The umcode_latest command lists or downloads the system resources that have an older firmware or microcode level than the firmware or microcode level that was found on the specified source for those system resources.

Note: System Firmware images of system types 8842/8844/7047/7013/7015/7017 and 7025-F50 are not supported by this command. For systems with temporary and permanent system firmware images, the umcode_latest command uses the temporary system firmware image for comparisons with the images on the specified source. System firmware image file names must end with .img.
