Use this information to solve undetermined problems.
If the Flex System chassis contains more than one compute node and only one of the compute nodes has the problem, troubleshoot the compute node that has the problem.
If DSA did not diagnose the failure or if the compute node is inoperative, use the information in this section.
If you suspect that a software problem is causing failures (continuous or intermittent), see Software problems.
Corrupted data in CMOS memory or corrupted UEFI code can cause undetermined problems. To reset the CMOS data, remove and replace the CMOS battery to override the power-on password and clear the CMOS memory; see Removing the CMOS battery. If you suspect that the UEFI code is corrupted, see Recovering a UEFI image.
The following minimum configuration is required for the compute node to start:
If the problem is solved when you remove an I/O expansion adapter from the compute node but the problem recurs when you reinstall the same adapter, suspect the I/O expansion adapter; if the problem recurs when you replace the adapter with a different one, suspect the system-board assembly.
If you suspect a networking problem and the compute node passes all the system tests, suspect a network cabling problem that is external to the system.
