Description Vasiliy Kotikov 2007-07-09 14:17:47 UTC 
Description of problem:
It is not possible to install OS, the system hangs on loading driver of  	Intel®
RAID Controller SRCSAS18E.
In RHEL5Server release notes, the problem with megaraid driver was mentioned "
driver must be set to operate in "Mass Storage" emulation mode", but the problem
appeared to find this <emulation>. There is no such thing in properties, see
http://www.intel.com/design/servers/raid/srcsas18e/

Version-Release number of selected component (if applicable):
RHEL 5 Server (ISOs downloaded from RHN) with kernel-2.6.18-8.el5

How reproducible:
1 variant: Take server with SAS SCSI disks on SRCSAS18E controller, start the
default installation.
2: I have installed on a "brother" server with another card MegaRAID SAS 8408E 
http://www.lsi.com/storage_home/products_home/internal_raid/megaraid_sas/megaraid_sas_8408e/index.html?remote=1&locale=EN
and after successful install of OS, HDD was moved to the server with the card
SRCSAS18E. (see attached picture)
3: ... I compiled a driver from sources, replaced the megaraid_sas driver as
desribed in this artilce
http://www.tuxyturvy.com/blog/index.php?/archives/4-Installing-RHEL4-on-Systems-with-Legacy-Megaraid-Drivers.html
and tried again => same result - it hangs on loading a driver.
Steps to Reproduce:
1.
2.
3.
  
Actual results:
System cannot load megaraid_sas driver.

Expected results:
megasas driver loads successfully on systems with Intel® RAID Controller SRCSAS18E

Additional info:
I do not know what to do... Intel did not release the driver for RHEL5 only for
RHEL4 (BTW: kernel goes to panic on loading driver of this controller...)

You are using very old driver Version 3.05.  Can you try 4.x driver?

Thx

No reply. Assuming this is resolved. Closing.
