M4000 / M5000 : How to assign IP address to XSCFU

By

To be able to manage (poweron/poweroff) and configure various domain related tasks such as domain creation, domain configuration etc.. we must have to setup XSCF on network. To confgure XSCF networking for the first time, you need to connect the serial port as shown in the diagram below (M5000 server example). Setting up XSCF networking Let us see an exmple of network confguration of XSCF on M5000 system. Below are the network settings which we will configure. Network … [Read more...] about M4000 / M5000 : How to assign IP address to XSCFU

How to collect XSCF snapshot on M-series servers (M3000 / M4000 / M5000 / M8000 / M9000)

By

This post describes the various ways to gather diagnostic data from either the XSCF or the domain and XSCF combined. Snapshot stores the collected data on a remote network host or on an external media device, based upon the use of the -T, -t or -d option. To store the collected data on a remote network host using the -t option, the command line must specify a host name (or IP address), a target directory on the remote network host, and the user name of a user on the remote host. When … [Read more...] about How to collect XSCF snapshot on M-series servers (M3000 / M4000 / M5000 / M8000 / M9000)

How to set OBP Variables from the ALOM/ILOM

By

It's handy to be able to set various OpenBoot variables from the System Processor (ALOM or ILOM) since sometimes it isn't possible to reach the OBP. From the ILOM Syntax to set any OBP variable from ILOM is as follows : -> set /HOST/bootmode script="value" For example, if you want to disable auto-boot because the system keeps hanging on boot: -> set /HOST/bootmode script="setenv auto-boot? false" If you want to change your console redirection because it was set badly: -> set … [Read more...] about How to set OBP Variables from the ALOM/ILOM

By

Sun Fire 3800, 4800, 4810, 6800, E4900, and E6900 System Controller (SC) software contains multiple shells. Each have specific functionality regarding administration of the platform. The shells include: 1. Domain Console: The domain's console device connection (/dev/console). When connected, the user will have one of the following prompts: a. OpenBoot Prom (OBP) b. console login 2. Domain Shell: A shell on the system controller with the ability to administer a specific domain on the … [Read more...] about SF3800/SF4800/SF4810/SF6800 – E4900/E6900 : connecting to a domain shell console which is already in use

How to dynamically replace CPU/memory board (dynamic reconfiguration) on SunFire s6800/e12K/e15K/e25K

By

Whats a dynamic reconfiguration? On s6800/e12K/e15K/e25K systems we may dynamically reconfigure CPU/memory boards, I/O boards and PCI on I/O boards with dynamic reconfiguration. The process is on-line and there is no interruption in the OS during this reconfiguration. This is useful when you want to replace a faulty system board on the system or configuring a system board from one domain to another domain. Prerequisites Before starting to remove the system board we have to make sure that … [Read more...] about How to dynamically replace CPU/memory board (dynamic reconfiguration) on SunFire s6800/e12K/e15K/e25K
