megacli not working for SAS 6/iR (LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS) on PE1950III running citrix xenserver 5.0.0

[Sabuj Pattanayek]

Well looks like I need a program called mpt-status for that device

In order to get it to compile (do it on a RHEL5 32 bit machine or on a
RHEL5 64bit system using -m32 in CFLAGS) you'll need the full kernel
source, either download linux-2.6.18.tar.bz2 from kernel.org or
install the latest RHEL5 SRPM. Modify the Makefile and then apply this
patch:

####

--- mpt-status.h.old	2009-03-05 00:13:05.916000000 -0600
+++ mpt-status.h	2009-03-05 00:13:14.671000000 -0600

 #define _MPT_STATUS_H

 #include <sys/ioctl.h>
-#ifdef __linux__
-#include <linux/compiler.h>
-#endif

 #ifdef SANITIZED_KERNEL_HEADERS
 #include "mpt-sanitized.h"

####

Then you'll need to "modprobe mptctl" in citrix xenserver because
although /dev/mptctl exists mpt-status will complain that it can't
talk to the device. Then it seemed to work without problems:

# ./mpt-status
