Two potential methods exist to get Smart Array controller models not supported by the hpsa driver recognized and potentially working.

Neither of these methods are supported by Red Hat.

  • The hpsa driver has the following module option hpsa_allow_any=1. This module option allows the use of PCI IDs that are not listed in the driver's pci-id table (recognition of Smart Array cards that are not tested/qualified with the hpsa driver). To make the installer detect the controller at install time, pass the following hpsa.hpsa_allow_any=1 at the install prompt. Per the RHEL 7 release notes, any cards detected by using this option are not supported by Red Hat.

  • Download the cciss driver from HP's open source project repository for the cciss driver. Since this resulting driver is not shipped by Red Hat, it isn't supported.
