Preface This document provides information about the using the Linux Recovery Utility for HP Integrity Servers. The Linux Recovery Utility facilitates recovery of your Linux operating system on HP Integrity servers by automating tasks such as hardware discovery, storage controller configuration, disk partitioning, and preparation of your system for Linux recovery. The Linux Recovery Utility is supplied on the Linux Recovery Utility CD for HP Integrity Servers.
1 Introduction to the Linux Recovery Utility This chapter provides a description of the software and documentation that are provided on the Linux Recovery Utility CD.
2 Using the Linux Recovery Utility CD The Linux Recovery Utility CD will enable you to install a factory pre-configured operating system image. When you run the Linux Recovery Utility, the bootloader loads a Linux kernel and RAM-based root file system. The kernel performs hardware discovery, looking for bootable devices, chip sets, ethernet cards, disk drives, and storage system controllers.
1. 2. Insert the Linux Recovery Utility CD in a drive and boot the machine. The EFI boot manager loads. At the Please select a boot option prompt, use your arrow keys to highlight Boot Option Maintenance Menu and press the Enter key. You must perform this step quickly, within several seconds, to avoid booting a default option. For example, if your machine already has an operating system installed, the EFI boot manager will boot it as the default.
1. Define console, baud rate, and parity information. • If the system is using a VGA console, skip this step and proceed to the next step (Step 2). • If the system has a serial console for its display, you must specify the port where the console is connected, the baud rate, and parity information, in the Kernel Options: box. This information identifies the console location to the kernel and configures it appropriately.
5. Select the disk on which to install the recovery image. On the Recover factory pre-configured image screen, the system's available storage devices will be listed. Use the arrow key to highlight the destination storage device where you want to install the recovery image, and select Ok to initiate the recovery operation. IMPORTANT: 6. 7. 8. All data on the storage device that you select will be destroyed. Click Ok on the Recovery Complete screen. Reboot the system when prompted.
A Configuring a Serial Console If available, the default console configuration for the HP Integrity server is a local graphics display using a USB keyboard and requires no setup. The display screen can also be a remote serial console connected through a serial port or through a terminal attached to a serial port. Examples include a management processor’s serial port or a network connection through a management processor that the system treats like a serial port.
B Using Smart Array with Linux On HP Integrity Servers This section provides information about using Smart Array with Linux on HP Integrity servers. For the latest information and for problems with an optional disk array controller board, refer to the appropriate manuals provided with the array controller.
C Frequently Asked Questions and Troubleshooting Information This section contains frequently asked questions and the answers to those questions. Some of the questions and answers supplied in this section provide troubleshooting information. How does the Linux kernel order serial ports (UARTs)? 1. 2. HCDP (Headless Console and Debug Port) Console UART is the UART set in the EFI Console- In/Out table. It will always be ttyS0 regardless of whether the operating system uses a serial console.
append="console=ttyS0" - The format of the console parameter is as follows: console=ttyS[,] = Serial line Note: for HP systems, ttyS0 is the *ONLY* valid line for a serial console. Exactly one UART MUST be selected in the EFI Console-In/Out tables for a serial console to work. ttyS0 is the UART selected in this table. = Speed. Ex: 9600, 19200, 38400, 57600, 115200 (9600 is the default if no speed is specified. 115200 is the maximum for HP UARTs) = Parity.
How are disks named in Linux? IDE disks are named /dev/hd where ‘n’ starts at ‘a’ and increases. Disk ‘a’ is the master on IDE channel 0, and ‘b’ is the slave on that channel. Disk ‘c’ is the master on IDE channel 1, and ‘d’ is the slave on that channel. IDE disks are not necessarily consecutive. That is, if you do not have a slave device on channel 0, disk w/ ID hdb is simply skipped. SCSI disks are named /dev/sd where ‘n’ is ‘a’ to ‘z’, then ‘aa’ to ‘az’, etc.
D Known Issues This section discusses any known problems or issues with this release of the Linux Recovery Utility. Fibre-Channel Cards Problem The Linux Recovery Utility does not work with the following fibre-channel cards: • AD168A • AD167A • AB379A If you are recovering a system that uses one of these cards, do not use the Linux Recovery Utility. Instead, you must use the Red Hat installation media to recover your system.
