We are going to upgrade a handful of ESX 4.1 hosts to 5.5 or 6, if the hardware supports. It is going to be a two step process, the first of which will be upgrade to 5.1 using the ISO. We need console access to do this. These are X series IBM servers. A part of our pre-upgrade checklist is to ensure we have IMM access.
We have one server where we cannot reach the IMM remotely. We have seen this before and managed to solve it by resetting the IMM via LanOverUsb or cold restart of the server- graceful shutdown of ESX(i), followed by unplug, plug both power supplies but not this time.
It is no brainer if you can access the IMM physically or remotely. But when you need someone to do it for you, picture helps.
Reboot the server and press F1 to enter setup. Then follow the pictures.
I am unable to open the web interface of IMM for an X series IBM server. I could ping it. I could ssh to it. So the IMM was clearly not hung. But nmap scan did not return port 80 or 443.

Dynamic System Analysis (DSA) is a tool from IBM which collects software and hardware information from a server running IBM Hardware. If you open a ticket with IBM support, they will ask for DSA log from the server in question.
From IBM website:
IBM DSA Portable Edition is a system information collection and
analysis tool that is used by IBM xSeries(R) Service and Support
personnel to aid in the diagnosis of system problems.
DSA collects information about the following aspects of a system:
- System configuration
- Installed packages
- Kernel Modules
- Network interfaces and settings
- Performance data and details for running processes
- Hardware inventory, including PCI & USB information
- IBM LightPath(TM) status
- Service Processor status and configuration
- Vital product data, firmware, and basic input/output system
- Drive Health Information
- ServeRAID configuration
- LSI RAID & Controller configuration
- Event logs for the operating system, ServeRAID controllers,
and service processors
To collect DSA logs from a server running Linux, Windows, ESXi and ESX
- Download the portable DSA
- Run the utility as root or Administrator
- Collect the output that looks like 7915AC1_XXXXXXXX_20160316-062400.xml.gz
- Send it to IBM
- There is no utility for ESXi but you can run the command from Linux or Windows with the
--vmware-esxi user:password@ip-address options.
