mpt2sas driver failure, Raid 1, RHEL 5.5 driver problem, PERC H200A
 

I have a Dell server power edge R410. I need to install RedHat Entherpris 5.5 and also need Raid 1. (Raid controller is PERC H200A)

I have set the Raid 1 through system configurations before I install OS (Hardware Raid) and everything seems to be working well. The problem is I get an error message when Linux is starting:

mpt2sas0: failure at drivers/scsi/mpt2sas/mpt2sas_scsih.c:4046/_scsih_add_device()!

after I tried all possible ways and drivers (I could get the driver for Linux 5.3 and installed it so the error message changed:

mpt2sas0: failure at /var/lib/dkms/mpt2sas/02.00.03.00/build/mpt2sas_scsih.c:5149/_scsih_add_device(()!

I have 2 questions:

1- Is this driver error message going to cause any problem now or in future? Considering the Raid 1 being set as hardware raid.

2- Is there any driver for RHEL 5.5 to solve this?
