I will also note that it is not an issue of compatibility between the LSI-provided MegaCli and the Dell PERC5/i. I use the exact same RPM under SuSE's SLES10 on the same hardware without any problems.

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.
