IBM SAN administration

IBM SAN administration

AIX SAN Management I: Administration (AN490) is designed to bridge the knowledge gap between AIX/PowerVM education and Storage Management courses. The overall objective is to provide you a description of how AIX interacts with Fibre Channel storage devices. Along with this general view, we will look at common operational issues such as performance and problem solving from the perspective of an AIX administrator.

Course outline

Unit 8: SAN Performance Monitoring Considerations

• Identify the I/O layers where queuing is handled • View and change a FC disk and FC disk adapter's tuning attributes • Monitor and tune the queue depth of disks and disk adapters • Identify the filemon reports that display I/O activity • Test I/O throughput using: o The time and dd commands o The ndisk program (part of the nstress package)

Unit 9: SAN Problem Determination

• Describe the FC problem determination process • Identify the FC path selection algorithms • Use the iostat -m command to display path priorities • List the attributes that are used for FC health checking • Define the FC reservation policies that can be used • Explain the purpose of fast I/O failure and dynamic tracking
