The driver for your device LSI Logic / Symbios Logic MegaRAID
[1000:1960] is disabled in the CentOS kernel (C6 and C7).

# CONFIG_MEGARAID_LEGACY is not set

You'd need a driver disk with the required driver to install CentOS on
your system. My suggestion is that you ask ELRepo to offer such a disk
by filing an RFE at http://elrepo.org/bugs .

Akemi,

That is a really good idea.  Did not know this could be done.

could you try `lspci -nn`,  this will return the vendor/device ID, which 
will pin down which megaraid it is.

but, I'm afraid the answer is, that hardware is way over 10 years old, 
and support has been dropped from newer OS releases.   Those raid 
controllers require not only specific drivers, but also support 
utilities for monitoring the status of the raids, and configuring them.

The Megaraid family started back under NCR/Symbios in the late 80s, LSI 
acquired what was left of Symbios in 1998, Avago acquired LSI in 2014, 
then merged with Broadcom  in 2016 (as I understand it, Avago acquired 
Broadcom, but then renamed themselves). Sadly, support for legacy 
hardware tends to evaporate in corporate takeovers as its seen as pure

Red Hat does discontinue support for some storage driver for very old 
hardware when they start a new release series.  For EL6, that list is here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Migration_Planning_Guide/sect-Migration_Guide-Package_Changes-Driver_Changes.html#sect-packages-discontinued-drivers

For 7:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/sect-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-Removed_Drivers.html

I did a cursory check, and don't see any drivers that were removed in 6 
present in 7.

Run 'lsmod' on the system you're currently running and see if you can 
locate the storage driver.  I'm guessing it's "megaraid" which is not 
present in EL7.

I'm curious just how OLD this SCSI RAID system is?   Everything I've 
deployed in the last 8 or 10 year has been SAS based, parallel SCSI went 
the way of buggy whips some years back, I think the last parallel SCSI 
servers I decommissioned were based on the Pentium-4 generation of Intel 
Xeon processors, like Nocona..


the power vs performance of these old servers makes them a losing bet, 
especially now that you're way on the wrong side of the typical 5 year 
halflife of computer electronics.a single socket low end modern 
server would have many times the CPU and IO performance, and would be 
able to run many such workloads virtualized.

What model LSI card?
Is that card on the RHEL hardware support list?
Does LSI/Dell have drivers on their site?
Have you tried drivers from LSI/Dell and using the dd(driver disk) option 
during install?

Steven, thank you for your help.

I do not have a RedHat subscription, but do have an account.  When I did
a search on "GEM359" it was not found.

I have not been able to wade through the Broadcom web site to see if
they have any drivers for the LSI, but have not finished.  I was not
able to find anything when I tried to use Centos 6; I was hoping that
this was remedied for Centos 7

I have never used the dd option during an install, but am willing to
learn.

I am, on IBM LS20 blades.  The SCSI controller, according to lspci, is:
02:02.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X 
Fusion-MPT Dual Ultra320 SCSI (rev 08)


I'm not using it in RAID mode.

I installed CentOS 7 on a machine with an LSI Ultra 320 SCSI card in it
and I don't remember having any problems. But there again, the OS on
that system is installed on a separate SAS MegaRAID drive and the SCSI
is just used for user files, so I never paid much attention to it
during install.

[CentOS] SCSI drives and Centos 7

2017-04-29 Thread Gregory P. Ennis 
Everyone,

about 4 years ago, I tried to install CentOS 6 on a Supermicro server
with SCSI drives using a LSI raid system.  I could never figure out or
find a way to make the installation disc of Centos 6 identify the SCSI
drives.  The installation disc for Centos 5 identified the SCSI drives
without a problem. I finally gave up on Centos 6 and installed Centos 5
and the system has worked very well for the last 4 years 

Now that Centos 5 has been retired, I would like to install Centos 7 on
this server.  Does the install disc for Centos 7 have the same issues
with SCSI drives as Centos 6?  Has anyone used Centos 7 on SCSI drives,
or am I going to need to get an upgrade of the server?  The server is
working great.

Greg Ennis
