How to Troubleshoot Sun ASR
Sun ASR (Auto Service Request) works to use support services to increase service availability while decreasing customer wait time. Through the ASR system, customers enjoy easily configured assets. Additionally, the Sun ASR system eliminates the need for users to personally monitor hardware errors and error logs. However, as with any system, Sun ASR is not without the occasional problem.

Call up the general Core Dump command, #dumpadm, to start troubleshooting a problem with your core Dump processes. Type “swap-1” to reveal whether or not there is enough room in the system for swap space to dump memory. If there is enough room, check that there is also enough room for core dump files by typing the command “df-k.” This should essentially verify and set up the Core Dump process for your system. However, if you wish to specify a certain location for a particular dump file, you may enter the following command to change where the files will be stored: “dumpadm-s.”

Stay up to date with firmware and software patch management. Usually available for free downloads, these patches provide ready-made solutions to many of the problems found in the regular Sun ASR. The Sun Patch Support Portal is the ideal place to find these patches, as it includes full and up-to-date information on all Sun ASR-related software patches and tools. If you are having difficulty with an issue in Sun ASR, first check the Sun Patch Support Portal to see if it is an inherent problem in the system that has since been corrected through a patch; if so, download and install the appropriate patch.

Enable the hardware watchdog mechanism. This mechanism acts just as its name suggests—as a watchdog. If your system’s hardware watchdog has been disabled, this could cause errors in the system. Correct the problem by first entering the “boot” command to reset the OS timer that enables the hardware watchdog to operate. If this does not work, try entering the “sync” command, which will generate a core dump file and reset the timer, and thus allow the hardware watchdog to properly function again.

Empty Serial Numbers: If the serial number for a product shows up as “empty,” correct the problem by using the SNEEP command. Prior to using this command, be sure to activate and install the Service Tools Bundle that is a prerequisite to the Sun ASR system.
