Dell MX9116n EMC SmartFabric OS10 User Guide Release 10.5.0 - Page 36

NOTE: OS10 has two images: A and B. One image is active, which is the current running version and used as the running software at the next system reload. The other image remains standby, used for software upgrades. The image install command installs the downloaded image to the system. If you had modified text files or installed custom packages, they would not be available with the standby image. Back up the modified files and reinstall the packages after downloading the standby image. NOTE: On an MX9116n Fabric Switching Engine and MX5108n Ethernet Switch, if you install an OS10 image using a DUP file, all firmware components are upgraded. The firmware upgrade is stored as a pending installation until you reload the switch. To view the contents of the firmware upgrade, use the show image firmware command. 7. (Optional) View the status of the software installation in EXEC mode. OS10# show image status 8. (Optional) Verify the standby image version in EXEC mode; for example: OS10# show boot Current system image information: Type Boot Type Active Standby Next-Boot --- Node-id 1 Flash Boot [A] 10.5.0.4 [B] 10.5.1.0 [B] standby OS10# show boot detail Current system image information detail: Type: Node-id 1 Boot Type: Flash Boot Active Partition: A Active SW Version: 10.5.0.4 Active SW Build Version: 10.5.0.4.650 Active Kernel Version: Linux 4.9.189 Active Build Date/Time: 2020-02-11T11:13:08Z Standby Partition: B Standby SW Version: 10.5.1.0 Standby SW Build Version: 10.5.1.0.123 Standby Build Date/Time: 2020-02-12T02:34:02Z Next-Boot: standby[B] NOTE: After the 10.5.1.0 image is installed successfully, using the boot system {active | standby} command does not have any effect and might not be reflected in the show boot detail command. The system boots up only with the 10.5.1.0 image in the next reload. This process is not reversible. Dell EMC recommends that you do not install 10.5.0.0 or an earlier image in this step. 9. Reload the new software image in EXEC mode. OS10# reload NOTE: During reload, the system enters and exits the ONIE environment automatically and boots using the 10.5.1.0 image. This reload takes a longer time than usual. You must not interrupt this reload process. 10. Use the show version command in EXEC mode to verify that the downloaded OS10 image is installed as the current running version.
