megacli and PERC5 (PowerEdge 1950) on 6.2

[Jonathan Delgado]

Hi,

    I have some Dell PowerEdge 1950 servers equipped with their PERC5/ 
i SAS RAID controller (OEM is LSI). In general they work fine. The  
mfi driver is being used and I get some occassional blurbs logged by  
the driver. I am having poor results though trying to get the megacli  
port (sysutils/linux-megacli) to work with it.

    For example, if I call 'megacli -AdpAllInfo -aALL' I get junk/ 
empty output like:
Adapter #0

    I am getting this result with multiple systems, one running 6.2- 
RELEASE p3, the other a recent (as of today) build of 6.2-STABLE. I  
am using linux_base-fc-4_9 for the Linux compat install, and the  
specific package of megacli is linux-megacli-1.01.09_1. linprocfs and  
linsysfs are both mounted. mfi_linux.ko is loaded. The device seems  
to be recognized within the linux subsystem, as I have:

# cat /compat/linux/sys/class/scsi_host/host0/proc_name
megaraid_sas

    From what I have been able to dig up from past posts to the  
mailing lists: others have been able to get this working fine, but  
I'm not sure if any have been specifically with 6.2 and the PERC5/i  
controller. If anyone has any clues or tips for how to proceed with  
this, it would be much appreciated.

    Thanks.
