Troubleshoot problems with hardware installation (for example, cableconnections).硬件安装故障判断 Troubleshoot problems with software installation (LED hang, system hang).软件安装故障判断（系统挂起） Troubleshoot problems with software (disk space, prerequisites, lslpp, and soon).软件故障判断 Troubleshoot hardware (for example, hardware parameters, cfgmgr,prerequisites, ODM tools).故障解决（使用类似cfgmgr等工具） Evaluate performance and resource problems (for example, check log files,skulkers, ps -ef).评价性能和资源问题(例如，检查日志文件,使用skulkers,ps-ef等命令）System and user maintenanceThe following are the system and user maintenance topics. Identify suspect hardware components before hard failure by monitoring errorlogs.通过察看错误日志，在出现硬件故障前鉴定有问题的硬件部件 Install necessary patches to prevent known problems.安装必要的补丁来避免所知问题的发生 Reboot servers (gracefully).重起服务器 Add, delete, and modify users.增加，删除和修改用户

Modify user environment (for example, modify initialization files, edit .profile,

edit dtwmrc, and so on).修改用户环境 Modify system environment.修改系统环境 Work with Volume Groups (add, import, remove, export, modify, list, and soon).使用VG Work with physical volumes (add, list).使用PV Work with logical volumes (add, remove modify, list, and so on). Work with file systems (for example, create, remove, modify, list, and so on). Modify paging space (increase size, add, remove, activate, list, and so on). Troubleshoot file system problems (for example, mount/unmount problems,file system full, and so on). Troubleshoot paging space problems (for example, low paging spaceconditions). Troubleshoot device related problems (for example, file system not availableat IPL, volume group not varying on IPL, SCSI device problems, and so on). Back up the system. Back up the applications. Back up the application data files. Restore files from tape. Establish a backup and recovery process based upon customerrequirements. Recover the system.CommunicationsThe following are the communications topics. Install device driver. Work with TCP/IP daemons (for example, start and stop TCP/IP daemons). Create interface (set IP address, set subnet mask, configure DNS). Configure interface (define node, gateway). Modify interface (change IP parameters). Configure TCP/IP services. Work with NFS (for example, start and stop NFS). Export directory (exportfs). Mount remote file system.Chapter 1. Certification overview 5 Troubleshoot hardware communications problems (for example deviceunavailable, device not functioning and so on). Perform TCP/IP troubleshooting (for example, daemons will not start/stop,cannot create a telnet session on a server, user cannot log on to server, andso on). Perform NFS troubleshooting (for example NFS daemon will not start/stop,host server is not responding, permission denied error messages).System performanceThe following are the system performance topics. Manage CPU and memory resources (for example, display CPU/memoryusage, start/stop a processor, and so on). Manage I/O performance resources. Manage network performance resources (show network, I/O counts,connections and queues). Manage workloads (for example, scheduling, setting up job queue, and soon).
