  1. Hp Cciss Driver Linux
  • Red Hat Enterprise Linux 7
  • HP Smart Array Controller

NOTE: The hpsa driver is a SCSI driver, while the cciss driver is a block driver. This means that logical drives which would be presented with devices nodes like '/dev/cciss/c0d0', etc. Will now be presented as '/dev/sda', etc. Easily find and download software and drivers for your HP products including pcs, laptops, desktops, printers, tablets, apps and services from HP Customer Support. Booting my system using the newer hpsa driver works fine (instead of the older cciss driver). My disks are detected as /dev/sda etc etc. However the HP provided tool 'hpacucli' fails to find any controllers. From what I have read this hpsa driver should support the same ioctls as cciss which enable.

Issue

  • Is cciss controllers supported in Red Hat Enterprise Linux 7 ?
  • Red Hat Enterprise Linux 7 does not have the cciss driver
  • Red Hat Enterprise Linux 7 fails to detect the P400 storage controller available with HP ProLiant DL380 G5

Resolution

  • Use a newer Smart Array controller model that is supported by the hpsa driver.

HP SmartArray RAID controllers - Linux driver differences (cciss versus hpsa) Ask Question. HP has a good write-up of what the differences are here. /dev namespace, which you already noticed. Modernized interaction with the SCSI layer in newer kernels. Hpsa is a SCSI driver, cciss is a block-driver. This will change device numbering, if. Hello, i have her a couple of server (HP DL380 G5) with an SmartArray P400 Raid-controller. This controller is not supported(by RH) anymore by the current hpsa-driver which is be the replacment vor the older cciss-driver in rh7, centos 6.5 works fine. HP has been transitioning away from the cciss Linux kernel-driver for a while now, but there hasn't been much information about what it all means. Just on the name alone the module needed a rename (one possible acronym of cciss: Compaq Command Interface for SCSI-3 Support), and it is a driver that. HP recommends using the standard cciss driver in SLES 11 SP1, since the included hpsa driver was an early experimental version. However, ProLiant Gen8 servers require the hpsa driver, since these servers contain.

Root Cause

  • As per the release note, The following cciss controllers are no longer supported:
    • Smart Array 5300
    • Smart Array 5i
    • Smart Array 532
    • Smart Array 5312
    • Smart Array 641
    • Smart Array 642
    • Smart Array 6400
    • Smart Array 6400 EM
    • Smart Array 6i
    • Smart Array P600
    • Smart Array P800
    • Smart Array P400
    • Smart Array P400i
    • Smart Array E200i
    • Smart Array E200
    • Smart Array E500
    • Smart Array P700M

Note: The above controllers are listed as no longer supported by the HP/HPE for use with the hpsa driver. You can try updating firmware to the latest versions, and that may get the cards at least recognized by the driver in some cases. However, since the vendor does not support these cards using the hpsa driver, if the card fails in any way we are unable to provide support as we're unable to engage the vendor through partner relationships for hardware they no longer support.

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

Alan Brown Le May (June 3, 1899 – April 27, 1964) was an American novelist and screenplay writer. He is most remembered for two classic Western novels, The Searchers (1954) and The Unforgiven (1957).

Description: THE SPIRIT OF THE WEST Alan LeMay will forever be known as the author of the brilliant novels that became the classic films The Searchers and The Unforgiven. But his short stories are no less memorable. Alan Le May was born June 3, 1899 in Indianapolis, Indiana; attended Stetson University and University of Chicago (Ph.B., 1922); began career as journalist; author of westerns, some of which were adapted to the screen, including The Searchers. Alan LeMay's classic 'The Searchers' has withstood the test of time which measures true greatness. His description of the rigors of late-century life on the Plains, and the on-going war between encroaching settlers and roaming Comanches, rings true for those who know those tales. Alan Brown Le May was an American novelist and screenplay writer. He is most remembered for two classic Western novels, The Searchers and The Unforgiven. They were adapted into the motion pictures 'The Searchers' and 'The Unforgiven'.

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.
