Validation Impact NOTE: When upgrading the connected PowerStore system to PowerStore OS version 1.0.2.0.5.003 (or later), AIX ODM version 6.2.0.1 is required when using PowerStore. To enable Fast I/O Failure for all fscsi devices, set the fscsi device attribute set fc_err_recov to fast_fail Stability and Performance To enable dynamic tracking of FC devices, Stability and set: Performance dyntrk= yes PowerStore operating systems earlier than Stability 2.1.0 do not support volumes larger than 2 TB with AIX. Severity Warning Warning Mandatory Refer to Section Fast I/O Failure for Fibre Channel Devices Dynamic Tracking 2 TB LUN Size Support 2 TB LUN Size Support PowerStore operating system versions earlier than 2.1.0 do not support SCSI command WRITE and VERIFY 0x8E (16) byte CDB that is used for volumes larger than 2 TB in size. If you must use volumes that are larger than 2 TB with AIX, it is highly recommended to upgrade to PowerStore operating system version 2.1.0 (or later). Otherwise, use volumes that are not larger than 2 TB. Boot from SAN For guidelines and recommendations for boot from SAN with AIX hosts and PowerStore, refer to the Considerations for Boot from SAN with PowerStore appendix. Fibre Channel Configuration This section describes the recommended configuration that should be applied when attaching AIX hosts to PowerStore cluster using Fibre Channel. NOTE: When using Fibre Channel with PowerStore, the FC Host Bus Adapters (HBA) issues that are described in this section should be addressed for optimal performance. NOTE: In general, no more than eight(8) paths per LUN should be used with an AIX host that is connected to PowerStore. If more paths are needed, an RPQ is required. Pre-Requisites Before you install HBAs on an AIX host, the following pre-requisites should be met. Follow the IBM recommendations for installation and setup of the appropriate HBA for your system. It is recommended to install the latest driver version (patch), as described on the IBM support site for each specific FC HBA. Refer to the E-Lab Interoperability Navigator (https://elabnavigator.dell.com) for supported FC HBA models and drivers. 72 Host Configuration for AIX
