Start the watch-net diagnostic test by typing the watch-net command at the ok prompt. For the watch-net-all diagnostic test, type watch-net-all at the ok prompt. CODE EXAMPLE 8-18 watch-net Diagnostic Output Message {0} ok watch-net Internal loopback test -- succeeded. Link is -- up Looking for Ethernet Packets. ‘.’ is a Good Packet. ‘X’ is a Bad Packet. Type any key to stop................................. CODE EXAMPLE 8-19 watch-net-all Diagnostic Output Message {0} ok watch-net-all /pci@1f,0/pci@1,1/network@c,1 Internal loopback test -- succeeded.

About Automatic Server Restart Note – Automatic Server Restart is not the same as Automatic System Restoration (ASR), which the Sun Fire V445 server also supports. Automatic Server Restart is a functional part of ALOM. It monitors the Solaris OS while it is running and, by default, captures cpu register and memory contents to the dump-device using the firmware level sync command. ALOM uses a watchdog process to monitor the kernel only. ALOM will not restart the server if a process hangs and the kernel is still running. The ALOM watchdog parameters for the watchdog patting interval and watchdog timeout are not user configurable. 194 Sun Fire V445 Server Administration Guide • August 2006
If the kernel hangs and the watchdog times out, ALOM reports and logs the event and performs one of three user configurable actions. ■ xir: this is the default action and will cause the server to capture cpu register and memory contents to the dump-device using the firmware level sync command. In the event of the sync hanging, ALOM falls back to a hard reset after 15 minutes. Note – Do not confuse this OpenBoot sync command with the Solaris OS sync command, which results in I/O writes of buffered data to the disk drives, prior to unmounting file systems. ■ ■ Reset: this is a hard reset and results in a rapid system recovery but diagnostic data regarding the hang is not stored, and file system damage may result. None - this will result in the system being left in the hung state indefinitely after the watchdog timeout has been reported. For more information, see the sys_autorestart section of the ALOM Online Help. About Automatic System Restoration Note – Automatic System Restoration (ASR) is not the same as Automatic Server Restart, which the Sun Fire V445 server also supports. Automatic System Restoration (ASR) consists of self-test features and an autoconfiguring capability to detect failed hardware components and unconfigure them. By doing this, the server is able to resume operating after certain nonfatal hardware faults or failures have occured. If a component is one that is monitored by ASR, and the server is capable of operating without it, the server will automatically reboot if that component should develop a fault or fail. ASR monitors the following components: ■ Memory modules ■ PCI cards If a fault is detected during the power-on sequence, the faulty component is disabled. If the system remains capable of functioning, the boot sequence continues. Chapter 8 Diagnostics 195
