Description
The Remote Supervisor Adapter performs many system management functions in an out-of-band mode (that is, without the involvement of the operating system). To be operational, the installation of both the hardware and software must be successful.
System management functions are provided by many software and hardware components, such as BIOS and UEFI system firmware, management controllers, such as the Baseboard Management Controller (BMC), Remote Supervisor Adapter (RSA), and other components, such as device drivers and operating system APIs. Systems with coexisting RSA-II and BMC hardware components prioritize the components; the RSA management functions have priority, while the BMC is accessed only when the RSA no longer functions.
Causes
The Remote Supervisor Adapter event occurs when a service processor or management module detects that the communication with the Remote Supervisor Adapter is either broken or that the RSA is not responding.
Implications
All of the system management utilities that rely on the Remote Supervisor Adapter might not work as designed.

Additional information
To download the latest RSA II daemon, the latest RSA firmware, or both, visit the "IBM System x support search" Web site, select "Download" for "Task", and then select the "Product Family", "Machine type", and "Operating system" values of interest. Then, to download the latest device driver, select "RSA" in the "Refine results" list; to download the latest RSA firmware, select "Remote Supervisor Adapter (RSA)" instead. In the result list, click the appropriate link. For BladeCenter x86 blade servers, visit the IBM BladeCenter support search Web site and follow similar steps.
To troubleshoot issues with the RSA daemon or the RSA, visit the "IBM System x support search" Web site, select "Troubleshooting" for "Task", and then select the "Product Family", "Machine type", and "Operating system" values of interest. Then, for "Refine results" select "RSA". In the result list, follow the appropriate links, and then read through the articles and follow the applicable instructions. For BladeCenter x86 blade servers, visit the IBM BladeCenter support search Web site and follow similar steps.
