Using the fmadm faulty Command The fmadm faulty command lists and modifies system configuration parameters that are maintained by the Solaris Fault Manager. The fmadm faulty command is primarily used to determine the status of a component involved in a fault. # fmadm faulty STATE RESOURCE / UUID -------- ------------------------------------------------------------- degraded dev:////pci@1e,600000 0ee65618-2218-4997-c0dc-b5c410ed8ec2 The PCI device is degraded and is associated with the same UUID as seen above. You may also see faulted states. fmadm config The fmadm config command output shows the version numbers of the diagnosis engines in use by your system, and also displays their current state. You can check these versions against information on the http://sunsolve.sun.com web site to determine if your server is using the latest diagnostic engines. # fmadm config MODULE VERSION STATUS DESCRIPTION cpumem-diagnosis 1.5 active UltraSPARC-III/IV CPU/Memory Diagnosis cpumem-retire 1.1 active CPU/Memory Retire Agent eft 1.16 active eft diagnosis engine fmd-self-diagnosis 1.0 active Fault Manager Self-Diagnosis io-retire 1.0 active I/O Retire Agent snmp-trapgen 1.0 active SNMP Trap Generation Agent sysevent-transport 1.0 active SysEvent Transport Agent syslog-msgs 1.0 active Syslog Messaging Agent zfs-diagnosis 1.0 active ZFS Diagnosis Engine Using the fmstat Command The fmstat command can report statistics associated with the Solaris Fault Manager. The fmstat command shows information about DE performance. In the example below, the eft DE (also seen in the console output) has received an event which it accepted. A case is opened for that event and a diagnosis is performed to solve the cause for the failure. 176 Sun Fire V445 Server Administration Guide • August 2006

For most Sun systems, this means the Solaris OS. Once the server is running in multiuser mode, you have access to the software-based exerciser tools, SunVTS and Sun Management Center. These tools enable you to monitor the server, exercise it, and isolate faults. Note – If you set the auto-boot OpenBoot configuration variable to false, the OS does not boot following completion of the firmware-based tests. In addition to the tools mentioned above, you can refer to error and system message log files, and Solaris system information commands. Error and System Message Log Files Error and other system messages are saved in the /var/adm/messages file. Messages are logged to this file from many sources, including the OS, the environmental control subsystem, and various software applications. Chapter 8 Diagnostics 177
