Using the Brocade Adapter Software Installer

• VMware systems
When upgrading the driver for VMware systems, you must reboot the host system. The new
driver is effective after system reboot. Because the ESX 5,0 driver installation process does not
enforce maintenance mode, it is recommended that you put the host in maintenance mode, as
since a system reboot is required after installation.
• Software installation or upgrade on a host system with a large number of adapters could take
much longer than normal.
NOTE
To make sure that the drivers and adapter boot code are synchronized, be sure to update your
adapter with the latest boot image from the Brocade adapters website
at www.brocade.com/adapters
whenever you install or update adapter driver packages. On the website , navigate to the drivers
Downloads page. Select your operating system from the Downloads list or download the ISO image.
Refer to
“Boot code updates” on page 118 for update instructions.
