Perc 6/e, megacli and new linux kernels

Question

Greetings.I have a problem with megacli and newer kernels with raid controller PERC 6/e.I use megacli for monitoring raid and disk status. After upgrading linux kernelto version >= 2.6.28 (currently i used 2.6.31-11, but i've the same situationunder 2.6.28), megacli can't find any adapters. As far as no sources of megacliavailable, it's very hard to track where the problem is. I suppose that megaclifails to find any adapters because of restructuring sysfs in newer kernels, butit's just a guess, which i can't surely approve.I've tried different versions of megacli 1.01.24 and 2.0.15, neither of it can'tfind perc controller.Raid array by it self works fine with all kernels i've tested.Here some usefull information:with kernel 2.6.24-23 (custom builded from ubuntu repository) everything works fine# modinfo megaraid_sasfilename: /lib/modules/2.6.24-23-yandex/kernel/drivers/scsi/megaraid/megaraid_sas.kodescription: LSI Logic MegaRAID SAS Driverauthor: version: 00.00.03.10-rc5license: GPLsrcversion: 134488BAF94ABCC2CC734BCalias: pci:v00001028d00000015sv*sd*bc*sc*i*alias: pci:v00001000d00000413sv*sd*bc*sc*i*alias: pci:v00001000d00000060sv*sd*bc*sc*i*alias: pci:v00001000d00000411sv*sd*bc*sc*i*depends: scsi_modvermagic: 2.6.24-23-yandex SMP mod_unload#lspci -v05:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04) Subsystem: Dell PERC 6/E Adapter RAID Controller Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at fafc0000 (64-bit, non-prefetchable) I/O ports at e000 [size=256] Memory at faf80000 (64-bit, non-prefetchable) [size=256K] Expansion ROM at faf70000 [disabled] [size=32K] Capabilities: [b0] Express Endpoint IRQ 0 Capabilities: [c4] Message Signalled Interrupts: Mask- 64bit+ Queue=0/2 Enable- Capabilities: [d4] MSI-X: Enable- Mask- TabSize=4 Capabilities: [e0] Power Management version 2 Capabilities: [ec] Vital Product Data# megacli -AdpAllInfo -aALL -NoLogAdapter #0============================================================================== Versions ================Product Name : PERC 6/E AdapterSerial No : 1122334455667788FW Package Build: 6.1.1-0047 Mfg.

I see 2 options: - downgrade to a kernel version that does work - wait for LSI to come out with a newer megacli that works with your kernel

PowerEdge HDD/SCSI/RAID
