Обновление стека по частям

Рассматривается обновление IOS с c3750-ipservicesk9-mz.122-53.SE до c3750-ipservicesk9-mz.122-53.SE2 на стеке из трех коммутаторов.
Обновляем софт

Перезагружать первый коммутатор отдельно желания не возникло по нескольким причинам:
1. Возникшие ошибки не приведут ни к чему хорошему.
2. Коммутатор имеет наивысший приоритет и после перезагрузки он снова станет мастером, а текущий мастер (в данном случае это был бы второй коммутатор) уйдет в перезагрузку.

UPDATE:

Error 9, Failed to open the file %9

Ошибка возникает при подключенной консоли. Так же консоль может вызвать рост CPU на 10-20 процентов.

Стеки 3750 и SDM

Если поискать статус коммутатора "SDM Mismatch", то выяснится, что коммутатор 3750-12S имеет отличный профиль от desktop по-умолчанию. Что-то про агрегацию там было... В общем, если на коммутаторах менялся профиль и к стеку подключается новый коммутатор, то необходимо установить на нем такой же профиль. Собственно, в логах об этом будет сообщено.

CME 7.1 для IOS 12.4.24T2

Принципиальное отличие набора файлов для Call Manager Express 7.1 от 7.0 в том, что изменен подход. Если в 7.0, как и в 4.1 была структура каталогов, например:

# tar tvf cme7.tar | grep "/$"
drwxrwxrwx  0 0      0           0 Dec 12  2008 bacdprompts/
drwxrwxrwx  0 0      0           0 Dec 12  2008 Desktops/
drwxrwxrwx  0 0      0           0 Dec 12  2008 Desktops/320x212x12/
drwxrwxrwx  0 0      0           0 Dec 12  2008 Desktops/95x34x1/
drwxrwxrwx  0 0      0           0 Dec 12  2008 gui/
drwxrwxrwx  0 0      0           0 Dec 12  2008 phone/
drwxrwxrwx  0 0      0           0 Dec 12  2008 phone/7906-7911/
drwxrwxrwx  0 0      0           0 Dec 12  2008 phone/7970-7971/
drwxrwxrwx  0 0      0           0 Dec 12  2008 ringtones/

то в 7.1 имеем архивы и ни единого каталога. Все файлы запакованы в один zip архив и это при том, что IOS умеет распаковывать только tar. Архивы, например, с прошивками так же не содержат каталогов.

Для чего это было сделано - непонятно. Есть предположение, что это связано с файловой системой на флешке.

Пусть необходимо развернуть прошивки из набора CME для телефонов 7911 на маршрутизаторе Cisco 3845 c IOS C3845-ADVIPSERVICESK9-M, Version 12.4(24)T2 и русифицировать их.
Для начала на flash с файловой системой FAT, позволяющей создавать каталоги, создается структура каталогов, аналогичная 7.0. Для удобства.

3845-voip#mkdir flash:/cme
Create directory filename [cme]? 
Created dir flash:/cme
3845-voip#mkdir flash:/cme/phone
Create directory filename [/cme/phone]? 
Created dir flash:/cme/phone
3845-voip#mkdir flash:/cme/phone/7906-7911
Create directory filename [/cme/phone/7906-7911]? 
Created dir flash:/cme/phone/7906-7911

Распаковывается с tftp-сервера архив с прошивками в созданный каталог

3845-voip#archive tar /xtract tftp://10.0.0.200/cme-124-24T/7906-7911-sccp.8-4-2S.tar flash:/cme/phone/7906-7911

Настраивается tftp-сервер на маршрутизаторе с алиасами на файлы, как это было до 7.1
