6 Host Configuration for AIX This chapter contains the following topics: Topics: • Related E-Lab Host Connectivity Guide • Recommended Configuration Values Summary • 2 TB LUN Size Support • Boot from SAN • Fibre Channel Configuration • Dell EMC AIX ODM Installation Related E-Lab Host Connectivity Guide The topics in this chapter detail specific caveats and configuration parameters that must be present when configuring an AIX host to access a PowerStore storage. These caveats and parameters should be applied with the configuration steps that are detailed on the E-Lab Host Connectivity Guide for AIX (see the E-Lab Interoperability Navigator at https:// elabnavigator.dell.com). Recommended Configuration Values Summary The following table summarizes all used and recommended variables and their values when configuring hosts for AIX. NOTE: Unless indicated otherwise, use the default parameters values. Validation Impact Severity To clarify the above note for using default parameter settings unless stated otherwise in this chapter, make sure that the following are set per the default OS setting: ● LUN and HBA queue depth ● HBA timeout Stability & Performance Recommended Fibre Channel Configuration: No more than eight (8) paths per LUN should be used with an AIX host that is connected to PowerStore. Stability & Performance Mandatory LUN Queue Depth: Performance Recommended If I/O throttling is required, the default depth value of 256 should be modified to a lower value. HBA FC max I/O size: max_xfer_size should be set to 1 MB.
