-An example of a time we'd want to use this is when a package from CentOS 7.3 has a bugfix we want to test on CentOS 7.2.  The RPM can be downloaded from the CentOS 7.3 repo, placed in the CentOS 7 lab-extras repo and installed.  Example: http://tracker.ceph.com/issues/18094
+An example of a time we'd want to use this is when a package from CentOS 7.3 has a bugfix we want to test on CentOS 7.2.  The RPM can be downloaded from the CentOS 7.2 CM (testing) repo, placed in the CentOS 7 lab-extras repo and installed.  Example: http://tracker.ceph.com/issues/18094
 ===== How-To =====
   - Obtain the RPM from a trusted source
     - e.g., ''yum install $package %%--%%downloadonly %%--%%downloaddir=/root''
-  - scp the package to the appropriate dir in ''gitbuilder.ceph.com:/home/apt-mirror/mirror/lab-extras/''
+    - serve it from http: accessible from the POK lab (say, on soko04, with "python3 -m http.server")
-  - ''ssh gitbuilder.ceph.com''
+    - read https://github.com/ceph/sepia-openshift/blob/main/apt-mirror/README.rst and follow the procedure there to update the repo in question
-  - ''createrepo %%--%%update /home/apt-mirror/mirror/lab-extras/centos7/''
 ===== Installing the package =====

 This updated the version to nfs-utils-1.3.0-0.**35**.el7.x86_64.  You can make sure no hosts got left behind by running ''ansible -a "rpm -qa nfs-utils" mira | grep -B 1 nfs-utils-1.3.0-0.33.el7.x86_64''.
+===== Micron NVMe Firmware Management =====
+This page describes how the Micron NVMe firmware used by trial nodes is managed.
+===== Supported firmware =====
+| Drive family  | Target firmware  |
+| Micron 7450   | E2MU300          |
+| Micron 7500   | E3MQ005          |
+The testnode Ansible role automatically detects supported Micron drives and upgrades them when the installed firmware is older than the target version.
+===== Firmware directory layout =====
+Firmware images are stored in the `lab-extras` repository using the following directory structure:
+<code>
+micron-nvme-firmware/
+├── 7450/
+│   └── E2MU300/
+│       └── Micron_7450_E2MU300_release.ubi
+└── 7500/
+    └── E3MQ005/
+        └── Micron_7500_E3MQ005_release.ubi
+</code>
+When adding support for a new firmware release, create a new version directory instead of replacing the existing files. For example:
+<code>
+/
+└── E2MU400/
+    └── Micron_7450_E2MU400_release.ubi
+</code>
+This page intentionally does not duplicate those instructions.
+===== Updating the Ansible role =====
+When a new firmware version is released:
+. Upload the firmware image to the appropriate directory in lab-extras.
+. Update the target firmware version in roles/testnode/tasks/micron_nvme_firmware.yml.
+. Update the firmware filename if necessary.
+. Verify on a trial node that the firmware is detected and upgraded successfully.
+===== Verifying firmware =====
+Check the currently installed firmware:
+<code>
+nvme list
+</code>
+or
+<code>
+nvme fw-log /dev/nvmeXn1
+</code>
+Example:
+<code>
+Firmware Log for device:nvme0n1
+frs1 : E2MU300
+</code>
+or
+<code>
+Firmware Log for device:nvme0n1
+frs1 : E3MQ005
+</code>
+===== Notes =====
+* Slot 1 is read-only on supported Micron drives.
+* Firmware is committed to slot 2 using activation action 3.
+* The Ansible role skips non-Micron NVMe devices automatically.
