If you are upgrading OS10 on a Z9100-ON switch, we recommend that you perform an ONIE fresh installation. See
Installation using ONIE for more information.
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 NotesRelease 10.5.0.
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.
CAUTION: Please do not use copy commands to download the image to the switch, as it may result in loss of
disk space for critical system applications and functions, and it may be difficult to locate the image.
1. (Optional) Backup the current running configuration to the startup configuration in EXEC mode.
OS10# copy running-configuration startup-configuration
2. Backup the startup configuration in EXEC mode.
OS10# copy config://startup.xml config://<backup file name>
3. Download the new software image from the Dell Support Site, extract the bin files from the tar file, and save the file in
EXEC mode.
OS10# image download file-url
For example:
OS10# image download ftp://userid:passwd@hostip:/filepath
NOTE:
Some Windows unzip applications insert extra carriage returns (CR) or line feeds (LF) when they extract the
contents of a .tar file, which may corrupt the downloaded OS10 binary image. Turn off this option if you use a
Windows-based tool to untar an OS10 binary file.
4. (Optional) View the current software download status in EXEC mode.
OS10# show image status
5. (Applicable only if you are presently running Release 10.5.0.x or earlier release and installing 10.5.2.0 or later now) Cancel any
staged firmware update using the image cancel command.
OS10# image cancel
6. Install the 10.5.2.0 or later software image in EXEC mode.
OS10# image install image-url
For example:
OS10# image install image://filename.bin
NOTE:
OS10 has two images: A and B. One image is active, which is the present 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 current software install in EXEC mode.
OS10# show image status
