Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Install OS10 upgrade

After you download and unpack a new OS10 binary image as described in Download OS10 image for upgrade, follow these steps:

NOTE During the OS10 image upgrade process in a VLT setup, when the VLT peers are running different software versions, make no configuration changes on a VLT peer. Ensure that both nodes are upgraded to the same version before you make any configuration change.

NOTE On an MX-Series I/O module, install OS10 upgrades in downloaded DUP files by following the instructions in the Dell EMC SmartFabric OS10 Release Notes—Release 10.5.0.

NOTE While performing an upgrade from 10.4.0E.R4S to 10.5.0.4 and later in GUI mode, all the IOMs may get upgraded with a time-out notification to the OME-M or an IOM (DNV Master) may not get upgraded. Check the IOMs to ascertain whether the upgrade was successful or not. If the IOMs did not get upgraded, re-initiate the upgrade for the impacted nodes.

(Optional) Back up the current running configuration to the startup configuration in EXEC mode.
```
OS10# copy running-configuration startup-configuration
```

Back up the startup configuration (startup.xml) in EXEC mode.

copy config://startup.xml ftp://userid:passwd@hostip/backup_filepath/10.5.0.4-startup.xml

Download the new OS10 binary image, also called the standby image, from a local server using the image download server-filepath/filename command in EXEC mode; for example:
```
OS10# image download sftp://admin:passwd@10.1.1.1/home/admin/images/OS10EE.bin
```
(Optional) View the current software download status in EXEC mode.
```
OS10# show image status
```
Cancel any staged firmware update using the image cancel command.
```
OS10# image cancel
```
Install the OS10 standby image using the image install file-url command in EXEC mode, where filename is the name of the image file downloaded in Step 3 with the image download command; for example:
```
OS10# image install image://OS10EE.bin
```
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.
(Optional) View the status of the software installation in EXEC mode.
```
OS10# show image status
```

(Optional) Verify the standby image version in EXEC mode; for example:

OS10# show boot
Current system image information:

OS10# show boot detail

Standby SW Version:       10.5.1.0
Standby SW Build Version: 10.5.1.0.123

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.

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.

Use the show version command in EXEC mode to verify that the downloaded OS10 image is installed as the current running version.

OS10# show version
