Section 1 - Installation and Configuration
A. System Planning
Identify customer's needs (e.g. architecture, scalability, physical requirements, etc.)
Determine future planning requirements (growth, product life cycles, etc.)
Analyze system deinstallation process (e.g. migration paths, etc.)
Establish strategy for crisis recovery
B. Install Initial Hardware
Verify physical requirements
Set up hardware
Set up base hardware communications
C. Install BOS
Install Base Operating System
Perform initial configurations (e.g. networks, paging space, date/time, root password, etc.)
Install LPPs
Install and configure other software systems (e.g. Netscape)
D. Perform Software Maintenance Activities
Apply software updates
Remove software
Maintain software licenses
E. Perform Upgrades
Upgrade Operating System (e.g. preservation and migration upgrades)
Create and install a mksysb
Perform alternative disk install
Upgrade hardware
F. Configure System Services
Configure printers and queues (e.g. Add, change, show or delete printers and queues)
Configure and manage resources (e.g. manage cron, configure skulkers, configure power management, etc.)
Configure devices (e.g. cfgmgr, tty, parallel and manual device)
Setup system environments (e.g. timezone, cultural environment, etc.)
Configure subsystems and subservers (e.g. start/stop system resource manager)
Configure SendMail
Configure X Server
Section 2 - Installation Problem Determination
A. Install and Upgrade Troubleshooting
Troubleshoot problems with hardware installation (e.g. cable connection, etc.)
Troubleshoot problems with software installation (LED Hand, System hang, etc.)
Troubleshoot problems with software (disk space, prereqs, lslpp, etc.)
Troubleshoot hardware (hardware parameters, cfgmgr, ODM tools, etc.)
B. Troubleshoot System Services
Troubleshoot printing problems
Evaluate performance and resource problems (e.g. check logfiles, skulkers, ps -ef, etc.)
Use syslogd to monitor system events
Configure and monitor logs (e.g.. Errord, syslod, etc.)
Section 3 - System and User Maintenance
A. Preventative Maintenance
Identify suspect hardware components before hard failure by monitoring error logs
Upgrade firmware/microcode
Install necessary patches to prevent known problems
Reboot servers (gracefully)
B. User Maintenance
Add users
Remove users
Modify users
Modify user environment (e.g. modify initialization files, edit.profile, edit dtwmrc, etc.)
Modify system environment
C. User Maintenance Problem Determination (from X Windows/CDE standpoint)
Troubleshoot CDE logins/hung CDE sessions
Troubleshoot GUI application startup
D. Storage Maintenance
Work with Volume Groups (add, import, remove, export, modify, list, etc.)
Work with physical volumes (add, list)
Work with logical volumes (add, remove modify, list, etc.)
Work with filesystems (e.g. create, remove, modify, list, etc.)
Modify paging space (increase size, add, remove, activate, list, etc.)
E. Storage Maintenance Problem Determination
Troubleshoot filesystem problems (e.g. mount/unmount problems, filesystem full, etc.)
Troubleshoot paging space problems (e.g. low paging space conditions)
Troubleshoot device related problems (e.g. FS not available at IPL, VG not varying on at IL< ScSI device problem, etc.)
F. Backup and Recovery
Backup the system
Backup the applications
Backup the application data files
Restore files from tape
Establish a backup and recovery process based upon various customer requirements
Troubleshoot backup and recovery problems
Recover the system
Section 4 - Communications
A. Install Hardware Communications (e.g. network adapter, modem, etc.)
Install hardware adapter
Install device driver
B. Work with TCP/IP
Work with TCP/IP daemons (e.g. start and stop TCP/IP daemons)
Create interface (set IP address, set subnet mask, config DNS)
Configure interface (define node, gateway)
Modify interface (change IP parameters)
Configuring TCP/IP services
C. Work with NFS
Work with NFS (e.g. start and stop NFS)
Export directory (exports)
Mount remote file system
D. Troubleshoot Communication Problems
Troubleshoot hardware communications problems (e.g. device unavailable, device not functioning, etc.)
Perform TCP/IP troubleshooting (e.g. daemons will not start/stop, cannot telnet to server, user cannot logon to server, etc.)
Perform NFS troubleshooting (e.g. NFS daemon will not start/stop, host server is not responding, "permission denied," etc.)
Section 5 - System Performance
A. Performance Management Challenges
Manage CPU resource (e.g. display CPU usage, start/stop a processor, etc.)
Manage memory resource
Manage I/O performance resource
Manage network performance resource (show network, I/O counts, connections and queues)
Collect a baseline (sar, etc.)
B. Performance Management Practices
Manage workloads (e.g. scheduling, setting up job queue, etc.)
Manage disk/data (partitions, RAID, Mirroring, defragmenting FS, etc.)
Manage networks (e.g. display network kernel and adapter options, measure network response, etc.)
Section 6 - Security
A. Establish System Security
Modify default password attributes for system users (e.g. maxage, maxlength, maxexpire, minrepeat, etc.)
Configure network services for security compliance (inetd.conf, rc.tcpip, rc.nfs, etc.)
