Advisory: Red Hat Enterprise Linux 7.1 - HP ProLiant Servers Loading HP Smart Storage Administrator (HPSSA), HP Smart Array Command Line Utility (HPSSACLI), or HP Smart Array Firmware Flash Utilities May Not Recognize HP Smart Array Controllers

DESCRIPTION

When attempting to run the HP Smart Storage Administrator (HPSSA), the HP Smart Array Command Line Utility (HPSSACLI), or updating the HP Smart Array controller firmware with HP smart components on an HP ProLiant server running Red Hat Enterprise Linux 7.1, the HP Smart Array Controllers may not be detected.

SCOPE

Any HP ProLiant server running Red Hat Enterprise Linux 7.1 attempting to run HPSSA or HPSSACLI or update the HP Smart Array controller firmware with HP smart components.

This is not HP specific and will affect all HP ProLiant servers running applications that rely on the "sg" generic SCSI driver. The sg driver is required to collect installed Smart Array controllers information; however, Red Hat Enterprise Linux 7.1 does not load the sg driver by default as previous Red Hat Enterprise Linux distributions.

RESOLUTION

This is targeted to be resolved in a future version of Red Hat Enterprise Linux.

As a workaround, to activate the driver on a running server, issue the command 'sudo modprobe sg.' The following command will create a file that will load the driver during the boot process:

sudo echo sg > /etc/modules-load.d/sg.conf

This issue is documented in the Red Hat Enterprise Linux 7.1 release notes as follows:

sg3_utils component, BZ#1186462
Due to the conversion of the iprutils package to use systemd instead of legacy init scripts, the sg driver is no longer loaded during system boot. Consequently, if the sg driver is not loaded, the /dev/sg* devices will not be present.
To work around this issue, manually issue modprobe sg or add it to an init script. After the sg driver is loaded, the /dev/sg* devices will be present and the sg driver may be used to access SCSI devices.

This advisory will be updated when additional information is available.
