Dell S3100 EMC Command Line Reference Guide for the Series 9.14.2.1 - Page 539

Version 8.3.19.0 8.3.11.1 8.3.7.0 Description Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Usage Information The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. Dell EMC Networking OS does not overwrite application core dumps so you should delete them as necessary to conserve space on the flash; if the flash is out of memory, the coredump is aborted. On the S-Series, if the FTP server is not reachable, the application coredump is aborted. Dell EMC Networking OS completes the coredump process and wait until the upload is complete before rebooting the system. Offline Diagnostic Commands The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, Dell EMC Networking OS results are saved as a text file (TestReport-SU-X.txt) in the flash directory. This show file command is available only on master and standby. Important Points to Remember • Offline diagnostics can only be run when the unit is offline. • You can only run offline diagnostics on a unit to which you are connected via the console. In other words, you cannot run diagnostics on a unit to which you are connected to via a stacking link. • The system stores the diagnostic results in the flash directory (TestReport-SU-X.txt). The system displays the following message after the diagnostic test is over. 05:37:17 : Diagnostic test results are stored on file: flash:/TestReport-SU-1.txt 05:37:22: %S3048-ON:1 %DIAGAGT-6-DA_DIAG_DONE: Diags finished on stack-unit 1 • Diagnostics only test connectivity, not the entire data path. diag stack-unit Run offline diagnostics on a stack unit. Syntax diag stack-unit number [alllevels | level0 | level1 | level2] verbose [testname | no-reboot] Parameters number Enter the stack-unit id. alllevels level0 level1 Enter the keyword alllevels to run the complete set of offline diagnostic tests. Enter the keyword level0 to run Level 0 diagnostics. Level 0 diagnostics check for the presence of various components and perform essential path verifications. In addition, they verify the identification registers of the components on the board. Enter the keyword Level1 to run Level 1 diagnostics. Level 1 diagnostics is a smaller set of diagnostic tests with support for automatic partitioning. They perform status/self test for all the components on the board and test their registers for appropriate values. In addition, they perform extensive tests on memory devices (for example, SDRAM, flash, Debugging and Diagnostics 539
