Updating FlashGrid software and Linux kernel using FlashGrid Server Update package (AWS) – FlashGrid Help Center

FlashGrid Server Update package is a single self-extracting bash script file that allows updating the following components:

FlashGrid Storage Fabric RPM
FlashGrid Diagnostics RPM
FlashGrid Cloud Area Network RPM
FlashGrid Health Checker RPM
Linux kernel (can be skipped)

Using this package makes it easier to have the update performed to the latest validated set of software components and helps avoid accidental installation of incompatible software versions.

Note: Please review corresponding release notes and check with FlashGrid support before performing any major version update. A major version consists of the first two numbers. The third number represents a revision (hotfix). For example, update from version 19.02.x to 19.05.x is major, but from 19.05.100 to 19.05.200 is a hotfix revision.
