Follow these general best practices for installing and configuring the HBA:
If more than one HBA model is present in the configuration, enable only the OptionROM (OpROM) for the first HBA seen in the boot sequence. There is a limited amount of space for OpROMs; therefore, do not unnecessarily enable all OpROMs, as space usage issues might occur.
When installing the HBA, be sure to also install the latest version of the command-line utility available from the manufacturer's web site. Keep the HBA utilities, firmware, and drivers up-to-date, and update them in that order.
