2) carefully check the README installed by RDAC.

2>. co-existence with Qlogic and LSI failover drivers
========================================================== ======================================
The RDAC driver cannot co-exist with an HbA-level failover
Driver such as the Emulex, Qlogic or LSI logic HbA failover drivers.
RDAC cannot coexist with fault-tolerant drivers of LSI or Qlogic.

3> requirements before RDAC driver package installation
-----------------------------------------------------------
A. It's assumed that the host system that you are
Installing the RDAC driver to has supported HbA's.

B. Although the system can have fiber re channel hbas from
Multiple Vendors or multiple models of hbas from
Same vendor, only the same model of hbas can be
Connected to each storage array.

C. It is assumed that the low level HbA driver has been
Properly built and installed before RDAC driver
Installation.

D. The standard HbA driver needs to be loaded before
The RDAC driver installation. The HbA driver has
Be a non-failover driver.

For Qlogic hbas, the base driver is named "qla2xxx"
And host driver is named "qla2300 ".

For LSI logic hbas, the port driver is named
Mptbase and the host driver is named mptscsi or
Mptscsih, for the MPT driver version earlier
3.02.xx. the 3.02.xx or later lsi mpt driver splits to three
Driver modules-mptspi, mptsas and mptfc for SCSI parallel
Interface transport, SAS transport and Fiber Channel
Transport respectively.

E. On the SuSE operating system, it is assumed that
Low level HbA driver names are supported in
Initrd_modules in/etc/sysconfig/kernel.

For the systems that have Qlogic HbA's, the modules
File shoshould include a qla2xxx and qla2300 (or qla2300 ).

For the systems that have LSI logic hbas, initrd_modules
Shocould include mptbase and mptscsi (or mptscsih)
For pre-3.02.xx version of lsi mpt driver. The initrd_modules
Shocould include mptbase, mptscsi, mptspi, mptsas and mptfc
For 3.02.xx or later version of lsi mpt driver.

For the systems that have IBM Emulex hbas, initrd_modules
Shoshould include lpfcdd or lpfc.

F. The kernel source tree for the kernel version to be
Built against shoshould already be installed before
RDAC driver package installation.

G. The glibc-devel (64 bit) package is required for 64 bit machines.

Summary:
Conditions Required Before RDAC is installed: A. The system has a supported HbA card, and B: the one-to-one HbA card model that the system connects to the disk array at the same time. C.
D. The driver of the HBA must be of the standard type, rather than the driver with a failed switch. E: For Qlogic, ala2xxx and qla2300 must be installed.
F: kernel source tree should be installed first. G: for 64-bit machines, glibc-devel (64bit) must be installed)

It seems that the conditions are met, unless the Qlogic HbA driver does not work, but we can see the disk array from the host, so it should not be the reason why the HBA driver does not work,
It is likely that the Redhat has several support packages that are not properly prepared, resulting in failure

4> lsmod check whether Qlogic's memory card driver is installed:

Find the solution on the Internet:
The reason for the error is that the appropriate package is not installed.
1> install the following packages: (red)

Install make
Make install
After installation, a file mpp-2.6.18-8.el5xen.img is generated on the boot menu

3.> use the compiled kernel as the IMG boot Guide
