Troubleshooting When troubleshooting issues with a device in your HP BladeSystem solution, keep in mind that the device is part of a solution, so correcting the issue may require a fair amount of analysis. Before contacting HP, gather information about the device, the solution, and the issue. When contacting HP, be sure to inform support personnel that the device is part of a BladeSystem solution. Gathering troubleshooting information Before contacting HP support, do the following: • Examine LEDs on all solution devices. • Follow and ensure integrity of all cabling paths. • Obtain System Event Logs from software tools, such as Onboard Administrator and Virtual SAS Manager. • Obtain the ADU Report. Troubleshooting the HP 6Gb SAS BL Switch Problem Amber LED on Switch Storage not ready during POST (blade) OR Controller lockup during POST VSM application is not accessible Unable to access the storage Solution • Check OA and VSM for status alerts to identify the problem. • See the HP 6Gb SAS BL Switch User Guide for LED definitions. Verify the power up sequence and allow sufficient time for each component to power up. Verify cabling from the switch to the storage enclosures. For more information about power-up sequence, see "Installation best practices and procedures" (page 52). For more information about cabling, see "Deployment examples" (page 71). Verify the power up sequence and allow sufficient time for each component to power up. Verify that the P711m, 712m, or P721m/P731m SAS controller is installed in the correct server expansion slot. The switch must be in the correct interconnect bay based on the expansion slot configuration. For more information, see "Device relationships and mapping information" (page 50). Troubleshooting MDS600 and D6000 storage enclosures For troubleshooting purposes, be sure to check the following: • Enclosure LEDs-show enclosure health status. • Fan, power supply, and I/O modules-show module health status. • 7-segment display panel-shows numeric codes that indicate a variety of self-discovered faults and warnings. By selecting the UID button on each drawer, the 7-segment display panel shows numeric codes that indicate why the GSI LED is enabled. • Cabling-make sure the cabling scheme is supported for use in this solution. NOTE: When the front-panel GSI LED or the rear-panel I/O module LED is Amber, in addition to indicating a potential issue with a physical component, it may indicate that firmware needs to be updated or re-installed on the I/O modules.
