How do I check my HMC memory?

When the HMC is at version 8.7.0, or later, complete the following steps to check the memory distribution for a logical partition:

  1. In the navigation pane, click the Resources icon .
  2. Click All Systems.
  3. In the work pane, select the system and click Actions > View System Properties.

What is Active memory Expansion?

Active Memory Expansion (AME) is a new technology for expanding a system’s effective memory capacity. AME employs memory compression technology to transparently compress in-memory data, allowing more data to be placed into memory and thus expanding the memory capacity of configured systems.

How will you see the HMC version in AIX?

Go to HMC Management. Hover over HMC Version at the top of the screen.

How do I view HMC logs?

  1. Standard Data Block.
  2. Secondary Data Block.
  3. Microcode Reason / ID Error Information.

How do you check top 5 memory consuming process in Linux?

One of the best commands for looking at memory usage is top. One extremely easy way to see what processes are using the most memory is to start top and then press shift+m to switch the order of the processes shown to rank them by the percentage of memory each is using.

How do I enable AME in AIX?

To activate this setting it requires you run the bosboot command followed by a reboot of the LPAR. Steps to enable all page sizes in an AME environment: On the HMC profile for the LPAR, enable AME with an expansion factor of 1.0 or with an expansion factor as recommended by the amepat command.

How does AIX calculate CPU usage?

How is CPU Utilization calculated for AIX server?

  1. Method 1: If ‘type=Dedicated’, then we use the vmstat command output. (
  2. Method 2: If ‘type=Shared’ , ‘mode=UnCapped’, and ‘smt=On’ , then cpu=lcpu/2.
  3. Method 3: If ‘type=Shared’ , ‘mode=UnCapped’, and ‘smt’ is disabled or not available , then cpu=lcpu.

How do I get HMC details from LPAR?

There are two ways to find the right HMC for the right LPAR. One way is to log on to the individual LPAR itself and list the HMCs that it connects to. This is quite straightforward, provided that the LPAR is up and running and has an active connection to the HMC.

How can I download historical CPU usage data from HMC?

With optional flags it is possible to download historical CPU usage data from HMC and to add it in the report. HMC performance data collection needs to be enabled on the HMC before running the scanner or the report will only have empty fields. Data collection is off by default on the HMC.

What data collection should be enabled on the HMC?

HMC performance data collection needs to be enabled on the HMC before running the scanner or the report will only have empty fields. Data collection is off by default on the HMC. The following tabs are related to managed system performance: CPU Pool Usage: monthly average history of CPU usage of each system.

How to collect performance data from a dual HMC setup?

If you have a dual HMC setup and want both HMCs to collect data, you need to enable collection on both HMCs. There is currently a bug on HMC software that prevents a full extraction of performance data using lslparutil command as hmcScanner does.

What is HMC (High Bandwidth Memory) Technology?

HMC uses standard DRAM cells but it has more data banks than classic DRAM memory of the same size. The HMC interface is incompatible with current DDR n ( DDR2 or DDR3) and competing High Bandwidth Memory implementations. HMC technology won the Best New Technology award from The Linley Group (publisher of Microprocessor Report magazine) in 2011.
