Recovering and Troubleshooting the iDRAC6 341
The Trace Log tracks the following information:
• DHCP — Traces packets sent to and received from a DHCP server.
• IP — Traces IP packets sent and received.
The trace log may also contain iDRAC6 firmware-specific error codes that are
related to the internal iDRAC6 firmware, not the managed system’s operating
system.
NOTE: The iDRAC6 will not echo an ICMP (ping) with a packet size larger than
1500 bytes.
Using the racdump
The racadm racdump command provides a single command to get dump,
status, and general iDRAC6 board information.
NOTE: This command is available only on Telnet,SSH and remote racadm
interfaces. For more information, see the racdump command in the RACADM
Command Line Reference Guide for iDRAC6 and CMC available on the Dell Support
website at dell.com/support/manuals.
Using the coredump
The racadm coredump command displays detailed information related to
any recent critical issues that have occurred with the RAC. The coredump
information can be used to diagnose these critical issues.
If available, the coredump information is persistent across RAC power cycles
and will remain available until either of the following conditions occur:
• The coredump information is cleared using the coredumpdelete
subcommand.
• Another critical condition occurs on the RAC. In this case, the coredump
information will be relative to the last critical error that occurred.
The racadm coredumpdelete command can be used to clear any
currently resident coredump data stored in the RAC. For more information,
see the coredump and coredumpdelete subcommands in the RACADM
Command Line Reference Guide for iDRAC6 and CMC available on the Dell
Support website at dell.com/support/manuals.
