firmware upgrade brocade 300

[hichem95]

HI,

I need to upgrade my firmware of my two brocade 300

I have the 7.0.0c version

I download the last version of the fabric os 7.4.1 in the website of brocade

but when i download with the ftp server he tell me "need files"

I download an other version of the fabric os 7.4.1a in the HP  but he needed to migrate on the version 7.2 before

I download the version of the fabric os 7.2.1 in the site of HP

http://h20564.www2.hpe.com/hpsc/swd/public/detail?swItemId=co_159155_1&swEnvOid=54#tab-history

But now he tell me

"The following item(s) need to be addressed before downloading the specified firmware:
Non disruptive firmwaredownload is not supported when firmwaredownload with two versions apart. Please try to use "firmwaredownload" with single mode option enabled.

Firmwaredownload failed."

Please help me

Thanks

i don't find the 7.0.2 but the 7.0.1 and after 7.1.0a

I can upgrade ?

Until you go to the steps 7.1.X, 7.2.X, 7.3.X, this is ok. Better is to use recommended reseller versions.

Keep in mind that besides the multiple one step upgrades (e.g FOS7.0.0 -> FOS v7.0.2 -> FOS v7.1.1) you could do the following starting from FOS 7.4.0:

Firmware clean install to FOS v7.4.1b from FOS v6.4 or later without retaining any configuration is supported.

But certainly make sure that it is applicable to your environment. It is disruptive.
