Обновление Cisco Nexus 5596 и прошивка Power sequencer

 И так нужна версия NXOS для которой есть утилита для обновления ПО секвенсеров.

Такая есть под 9.7.1.4.N1.1

Соответственно заливаем ПО на buutflash, всего нам нужно 4 файла:

n5000-uk9.7.1.4.N1.1.bin

n5000-uk9-kickstart.7.1.4.N1.1.bin 

nuova-or-dplug-mzg.7.1.4.N1.1.bin

ucd-update.tar

Далее устанавливаем NXOS:

sh incompatibility system bootflash:n5000-uk9.7.1.4.N1.1.bin

show install all impact kickstart n5000-uk9-kickstart.7.1.4.N1.1.bin system n5000-uk9.7.1.4.N1.1.bin 

Если ничего критичного не видим то устанавливаем.

install all kickstart n5000-uk9-kickstart.7.1.4.N1.1.bin system n5000-uk9.7.1.4.N1.1.bin 

Если все успешно нам предложат перезагрузиться:

Switch will be reloaded for disruptive upgrade.

Do you want to continue with the installation (y/n)?  [n] y 

Далее из консоли надо загрузить утилиту:

load bootflash:nuova-or-dplug-mzg.7.1.4.N1.1.bin 

Loading plugin version 7.1(4)N1(1)

Successfully loaded debug-plugin!!!

 Нужно распаковать обновление секвенсеров:

Linux(debug)# cp /bootflash/ucd-update.tar /tmp

Linux(debug)# tar -xvf ucd-update.tar

Linux(debug)# cd /tmp/ 

и выполнить файл который их обновит:

Linux(debug)# ./ucd.bin 

Если все пойдет по плану то должен быть примерно такой вывод:
