For system-specific information about the action that you should take as a result ofa message that DSA generates, see DSA messages.If you cannot find a problem by using DSA, see “Solving undetermined problems”on page 177 for information about testing the server.Note: DSA Preboot might appear to be unresponsive when you start the program.This is normal operation while the program loads.Make sure that the server has the latest version of the DSA code. To obtain DSAcode and the Dynamic System Analysis Installation and User's Guide, go tohttp://www.ibm.com/support/entry/portal/docdisplay?lndocid=SERV-DSA.DSA editionsTwo editions of Dynamic System Analysis are available.v DSA PortableDSA Portable Edition runs within the operating system; you do not have torestart the server to run it. It is packaged as a self-extracting file that youdownload from the web. When you run the file, it self-extracts to a temporaryfolder and performs comprehensive collection of hardware and operating-systeminformation. After it runs, it automatically deletes the temporary files and folderand leaves the results of the data collection and diagnostics on the server.If you are unable to restart the server, use DSA Portable.v DSA PrebootDSA Preboot runs outside of the operating system; you must restart the server torun it. It is provided in the flash memory on the server, or you can create abootable media such as a CD, DVD, ISO, USB, or PXE using the IBMToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMCInstallation and User's Guide at http://www.ibm.com/support/entry/portal/docdisplay?lndocid=TOOL-BOMC. In addition to the capabilities of the othereditions of DSA, DSA Preboot includes diagnostic routines that would bedisruptive to run within the operating-system environment (such as resettingdevices and causing loss of network connectivity). It has a graphical userinterface that you can use to specify which diagnostics to run and to view thediagnostic and data collection results.DSA Preboot provides diagnostics for the following system components, if theyare installed:– Emulex network adapter– Optical devices (CD or DVD)– Tape drives (SCSI, SAS, or SATA)– Memory– Microprocessor– Checkpoint panel– I2C bus– SAS and SATA drivesIf you are able to restart the server or if you need comprehensive diagnostics,use DSA Preboot.For more information and to download the utilities, go to http://www.ibm.com/support/entry/portal/docdisplay?lndocid=SERV-DSA.150 IBM System x3550 M4 Type 7914: Installation and Service Guide
