IBM HS22 Blade loses connectivity intermittently

As of ASU (Advanced Settings Utility) version 82k/9.50, out-of-band communication to blade IMMs is supported.

Here is an excerpt from pages 83-84 of the ASU user manual (http://download.boulder.ibm.com/ibmdl/pub/systems/support/system_x_pdf/ibm_util_asu_asu82k_anyos_noarch.pdf):

OOB Configuration for blades on AMM

ASU supports the configuration of blade settings through the out-of-band (OOB) mode. This section describes how to use it to configure blades on AMM.

The OOB configuration is designed to configure settings of blades on AMM. Before you use this function, ensure that the following requirements are met:

• The remote blades on AMM are connected to your network environment.
• The blade is an IMM-based server.
• Add the --slot argument to force ASU to connect with the remote AMM. If not, ASU will try to establish a connection with the provided IP address in an IMM out-of-band mode by default. And the --slot argument also can identify the blade's IMM node bay.

• Add the --host, --user and --password connectivity options because it is on out-of-band mode.

  – --host provides the IP address of the remote AMM where the blade is.

  – --user and --password authenticate to the AMM.

Command Examples:

To show a remote blade UEFI setting: asu show uefi --host x.x.x.x --user xxx --password xxx --slot x

To set a remote blade setting: asu set SETTING_NAME xxx --host x.x.x.x --user xxx --password --slot x --port 6090

In the examples, --host x.x.x.x is the IP address of the remote AMM, --user xxx and --password xxx are used to authenticate the connection, --slot x refers to the IMM node bay of the blade, and --port provides the port number for AMM chassis interface; the default is 6090.

The commands supported by OOB configuration for blades on AMM are listed below.
