IBM IMM памятка по доступу
В мемориззз...
на примере сервера x3650M4 - интерфейсы IMM - на первом гигабитном и выделенный отдельный интерфейс (GE1 - IMM1 + IMM2).
Для доступа в BIOS - F1 при старте системы (там в настройках IMM можно посмотреть выданный по DHCP адрес).
Из описалова:
Open a web browser and in the Address or URL field, type the IP address or host name of the IMM to which you want to connect.
Note: If you are logging on to the IMM for the first time after installation, the IMM defaults to DHCP. If a DHCP host is not available, the IMM assigns a static IP address of 192.168.70.125.
On the Login page, type the user name and password. If you are using the IMM for the first time, obtain the user name and password from your system administrator. All login attempts are documented in the event log.
Note: The IMM is set initially with a user name of USERID and password of PASSW0RD (with a zero, not the letter O). You have read/write access. You must change this default password the first time you log on.
On the Welcome page, type a timeout value (in minutes) in the field that is provided. You are logged off the web interface if your browser is inactive for the number of minutes that you entered for the timeout value.
Click Continue to start the session. The System Status page provides a quick view of the server status.
например,
http://192.168.41.169/designs/imm/index-console.php#80
логин по умолчанию - USERID
пароль по умолчанию - PASSW0RD
(в пароле вместо буквы "О" - цифра "0" - ноль).
Также есть доступ по SSH:
login as: USERID
Using keyboard-interactive authentication.

Network Discovery (LLDP, OADP) на коммутационных модулях ALAXALA в Hitachi Blade CB2000
После пары часов попыток "подружить" discovery в L2 между модулем
обозначающемся в инвентори как:
Type : 1G LANSW
Part/Model Number : GV-BE2LSW1X1-Y
(это свич-модуль ALAXALA)
и Huawei, в частности, с использованием LLDP, решил таки покурить маны и нашел вот это:
...
(2) About compatibility with LLDPs uniquely supported by other vendors
The Link Layer Discovery Protocol (LLDP) supported by the Switch is not compatible with
LLDPs uniquely supported by other vendors#.
#
Cisco Systems: CDP (Cisco Discovery Protocol)
Extreme Networks: EDP (Extreme Discovery Protocol)
Foundry Networks: FDP (Foundry Discovery Protocol)
(3) About compatibility with the IEEE 802.1AB standard
The LLDP used by the Switch is based on IEEE 802.1AB Draft 6, but includes unique extensions.
It is therefore not compatible with the IEEE 802.1AB standard.
...
выделено жирным и подчеркнуто мной, кстати, своего "товарища" он увидел.
Также в мемориз: настройка и глобально и на портах:
(config)# lldp run
!(config)# do sh lldp
Status: Enabled Chassis ID: Type=MAC Info=0000.**
Interval Time: 30 Hold Count: 4 TTL: 120
Port Counts=0
!(config)# int range gi 0/1-4
!(config-if-range)# lldp ena
!(config-if-range)# exit
!(config)# do sh lldp
Status: Enabled Chassis ID: Type=MAC Info=0000.**
Interval Time: 30 Hold Count: 4 TTL: 120
Port Counts=4
0/1 Link: Down Neighbor Counts: 0
0/2 Link: Up Neighbor Counts: 0
0/3 Link: Down Neighbor Counts: 0
0/4 Link: Up Neighbor Counts: 0
когда появляется сосед запись примерно такая:
System Description: ALAXALA AX3640S GV-BE2LSW1N1 [GV-BE2LSW1N1] Switching software Ver. 10.7.F [OS-L3A]
Total Neighbor Counts=1
В OADP можно включить поддержку CDP, однако эффекта на линках с Cisco тоже замечено не было.
oadp run
oadp cdp-listener
interface range gigabitethernet 0/1-4
oadp enable
В общем, не торт...(((

MS Windows Server 2008R2 MPIO
В мемориз...
после подключения полки Hitachi HUS110 по всем 8ми путям в разделе Управление Дисками будут 8 одинаковых неразбитых диска, чтобы они стали полноценным одним, нужно настроить многопутевой ввод/вывод (есть встроенный в систему или с диска от вендора).
Штатный виндовый:
Устанавливаем компонент "Многопутевой ввод-вывод"
Администрирование - MPIO
Обнаружение многопутевых устройств
HITACHI DF600F Добавить
Перезагрузка
После перезагрузки в Хранилище / Управление дисками - обычным образом добавить Диск.
