similar to: CentOS 6, mini-SAS and eSATA

Hi, For some time now (starting with the 3.10 or 3.11 kernels, but I'm not sure) I have the following problem: I have a machine with 6 SATA slots and two SAS controllers, one onboard HBA and one RAID controller in a PCIe slot. The problem is that the order of the SAS controllers changes randomly after a reboot, so the SCSI addresses of the devices change. One time lsscsi prints (empty

Thanks, Nux!. But a few hours late.

LSI/Avago?s web pages don?t have any downloads for the SAS2308, so I think I?m out of luck wrt MegaRAID. Bounced the node, confirmed MPT Firmware 15.10.09.00-IT. HP Driver is v 15.10.04.00. Both are the latest from HP. Unsure why, but the module itself reports version 20.100.00.00: [root at r1k1 sys] # cat module/mpt2sas/version 20.100.00.00 On 2016-05-25, 3:20 PM, "centos-bounces at

Hello, I've recently been given domain over a number of supermicro storage servers using Broadcom / LSI SAS2004 PCI-Express Fusion-MPT SAS-2 [Spitfire] (rev 03) to run a bunch of SSDs. I was attempting to do fresh installs of CentOS 8 and have come to find out that RedHat deprecated support for a number of HBAs for 8 including all running the SAS2004 chip. Does anyone know if there is a

I''m wondering if FLR really must be supported by the PCI card for PCI/VGA passthrough to work or if it will work anyway. I have read in the VTdHowTo that trying to pass through hardware without the FLR feature will result in an error. At the same time I read on a pdf document on the VMWare website (http://www.vmware.com/files/pdf/techpaper/vsp_4_vmdirectpath_host.pdf) that:

I have tried many permutations of search terms in google and I haven't been able to find any confirmation that the megaraid* modules in centos4 supports port multipliers/multiplexers. Here is a link to the controller I have in mind at newegg: http://www.newegg.com/product/product.asp?item=N82E16816118032 In case anyone is interested, here is what my research has turned up when looking for

Dear all, actually I installed CentOS 5.4 x86_64 on 11 new Dell R710 servers. It is required to use 5.4 to be covered by the NetApp Interoperability Matrix for use of Snapdrive. All systems spit out the error message mpt2sas0: failure at drivers/scsi/mpt2sas/mpt2sas_scsih.c:4637/_scsih_add_device()! at boot time. In dmesg the complete SCSI initialization logging appears as follows: SCSI

Hi again, thanks for all the replies to the all in one with ESXi, it was most illuminating. I will use this setup at my dayjob. Now for a slight variation on a theme: N40L with ESXi with raw drive passthrough, with OpenIndiana/napp-it NFS or iSCSI export of underlying devices. This particular setup is for a home VMWare lab, using spare hardware parts I have around. I''m trying to do

I always(!) flash these with the IT firmware that turns them back into a

Has anyone ever triend to hang a eSATA drive chasis off oc a centos box? Not specifically this box, but something like this.... http://www.compsource.com/ttechnote.asp?part_no=DS1220&src=F I have used internal SATA drives on 3ware cards before without an issue. Didn't know if this was in the same arena. Thanks! Andrew

Does any one know how to, if at all possible currently, to export a block device via eSATA? i.e. how do I do something like iSCSI, but over eSATA? I have a cheat ($15 probably?) media player at home (Egreat EG-M31B Network Media Tank - awesome little machine) that runs some flavor of Debian and can be connected to any PC via eSATA as an external HDD's. i.e. it exports the built-in HDD as a

Hey, just bought an eSATA/USB dual drive docking station and my CentOS 5 can only see one drive at a time... Any one knows if there are specific parameters to set somewhere? Or do I need a more recent kernel (like upgrading to CentOS 6?) The docking is a Sharkoon Quickport Duo v2 + 2 drives + 1 eSATA cable... http://www.sharkoon.com/?q=en/content/sata-quickport-duo-v2 The eSATA controller is an

So I'm curious how SAS JBOD arrays and linux MDraid as implemented in CentOS6, and SES (SCSI/SAS Enclosure Services) backplane controllers 'get along' and how much configuration is needed to get the warning lights to work properly. scenario: whitebox server with a SAS backplane or two, daisy chained on a SAS HBA (like an LSI Logic 2008), and disks organized as several raid5/6
