Upgrading Brocade Switch Firmware

This post discusses the process to update a Brocade Fibre Channel switch. You will require an FTP server to complete the process.

Pre-Upgrade Tasks

Before updating the Fabric OS on your Brocade switches complete the following steps:

1 Find the current firmware version and check compatibility. Check the current firmware version by entering at the CLI

firmwareshow

Verify the upgrade path from within the Brocade Fabric OS Upgrade Guide which you will find in the Brocade document library. As shown in the table below upgrade between one release is online more than this will require a reboot of the switch.  So check you are happy with your multipathing setup on hosts before continuing.

If you have other switches connected to the switch you are upgrading check for computability in the Brocade Fabric OS Release Notes.

7 If the switches are in a fabric run the commands below and take a note of the setting.  You will run these commands again after to ensure the fabric is healthy

7 Download the switch firmware from Brocade

8 Extract the Zip file and place it on your FTP server

Upgrading the Brocade switch firmware

1 Connect to the switch with an admin account

2 Enter the command firmwaredownload and follow the prompts.  If you are upgrading from 7.4.x or earlier you will need to use firmwaredownload -s.  firmwaredownload -s just commits the updated firmware to one partition you manually need to commit it to the second.  This can be a useful way of testing an update and reduces the risk of upgrade.  This is the procedure that is covered in this post, once you are happy with the update you will commit to both partitions

3 Follow the prompts:

Enter the IP address of the FTP server

Host IP or Host Name: 10.10.10.5

Enter a username with access to the FTP server

User Name: anonymous

Enter the location of the firmware upgrade files. In the example below I have copied the upgrade files for v8.1.0 to the root directory of the FTP server

File Name: v8.1.0/v8.1.0c

Select the protocol the FTP server uses

Protocol (ftp | scp | sftp): ftp

Enter the password for the user account you selected

Password:

4 You will then see the switch update begin which will take aprox 30mins.

2 switch update progress

You can see all the steps  that were taken taken below

FCSWITCH1:admin> firmwaredownload -s
Server Name or IP Address: 10.10.10.5
User Name: anonymous
File Name: v8.1.0/v8.1.0c
Network Protocol(1-auto-select, 2-FTP, 3-SCP, 4-SFTP) [1]: 2
Password:
Do Auto-Commit after Reboot [Y]: n
Reboot system after download [N]: y
Server IP: 10.10.10.5, Protocol IPv4
Checking system settings for firmwaredownload...</spanSystem settings check passed.>

Post Upgrade Checks

1 Once the upgrade is running you can check progress using:

firmwaredownloadstatus
 [1]: Tue Aug 15 21:46:28 2017
 Firmware is being downloaded to the switch. This step may take up to 30 minutes.

[2]: Tue Aug 15 21:52:21 2017
 Firmware has been downloaded to the secondary partition of the switch.

2 When the process is finished you can check the switch firmware (Fabric OS) is at the expected version

Appl     Primary/Secondary Versions
------------------------------------------
FOS       v8.1.0
          v8.1.0

3 If your switch is in a fabric check the fabric is healthy with the following commands and check against the values you noted earlier

fabricshow

nsshow

nsallshow

If you ran the firmwaredownload without the -s command, that’s it your done. If not you can let things run for a bit and then you need to commit the firmware to the second partition

Committing the firmware

1 Enter the command below to confirm the primary partition is running the correct level of firmware

2 Next commit the firmware

firmwarecommit

4 You can view the progress of the update

5 Finally now check that both partitions are running the correct firmware version

  1. It should be mentioned here that using Brocade Network Advisor is a MUCH preferred way of doing firmware upgrades.

  2. How about configuration?, I want do upgrade but ¿there are risk that zones and configuration will vanished?.

    thank you for guidance

    1. There is always a risk with any firmware upgrade. Make sure you have switch backups in place before starting any upgrade work
