Hi LSI MegaRAID/Linux team, There's a LSI 1068 chip that can be found on NEC hardware (also Intel/Supermicro/Hitachi, ...) and that can provide RAID 0 and 1 based on a MegaRAID BIOS. By setting a jumper, LSI1068 chip can be used in 2 modes: - LSI1068 'MPT-Fusion': pciid 1000:0054 embedded MPT-Fusion BIOS used with MPT-Fusion (SAS) Linux driver, from kernel.org (no issue in this mode) - LSI1068 'MegaRAID': pciid 1000:0055 embedded MegaRAID BIOS, providing RAID 0 and 1 But in this last mode, there's no way to use this chip with megaraid driver from kernel.org (so no way to use RAID device created by MegaRAID BIOS) => There's a driver provided by several vendors (Intel, Supermicro, ...) for RHEL and SLES, and that can be found on the web. This driver is named 'megaswr' (aka 'megasr', MegaRAID software RAID driver): ========================================================== > [root@iotiger2 x86_64]# modinfo megaswr.ko > filename: megaswr.ko > parm: low_mem_g:Set to 1 to simulate low mem condition > parm: dbglvl_g:driver-wide debug flag > license: GPL > description: LSI Logic SofrRAID Driver > author: LSI Logic Corporation > alias: pci:v00000000d00000000sv00000000sd00000000bc*sc*i* > alias: pci:v00000000d00000000sv00000000sd00000000bc*sc*i* > alias: pci:v00000000d00000000sv00000000sd00000000bc*sc*i* > ... > alias: pci:v00000000d00000000sv00000000sd00000000bc*sc*i* > alias: pci:v00000000d00000000sv00000000sd00000000bc*sc*i* > depends: scsi_mod > vermagic: 2.6.9-22.ELsmp SMP gcc-3.4 ========================================================== Do you have any information about this driver ? Seems that it is provided under GPL license. Who can provide the sources for this module ? (only binary are provided) Regards -- Frederic TEMPORELLI -------- Message original -------- Sujet: RE: Fw: SAS1068 PCI-X Fusion-MPT SAS 1000:0055 Date: Mon, 5 Feb 2007 10:04:28 -0700 De: Moore, Eric <Eric.Moore@xxxxxxx> Pour: Frederic TEMPORELLI <frederic.temporelli@xxxxxxxxxxxx> Copie: <linux-scsi@xxxxxxxxxxxxxxx> The 2.6.9-22.EL kernel is RHEL4 Update 2. You may want to contact someone from the LSI MegaRAID group, or Red Hat since this is a binary only deliverable. You should be able to find a MegaRAID contact in the MAINTAINERS file in the top directory of the kernel source tree. I work on mpt fusion drivers, which is a seperate division within LSI.
