Hi everybody. I have an HP StorageWorks array connected to one of my servers, connected via an LSI controller (lspci reports: SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)) on an HP DL385 running CentOS 5.5 x86_64. I have set up multipath and all is working but, when I create a snaphost and export it as a new LUN from the HP web interface, it

mkinitrd relies on /sys/class/scsi_host/*/proc_name instead of /sys/block/sd*/device/../../../moalias to get the scsi driver module name. As a fallback the sysfs driver name could be used, which does not match the module name either ('storvsc' vs. 'hv_storvsc'). Signed-off-by: Olaf Hering <olaf at aepfle.de> ---...

...oes anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in bios), no HW raid. I found, something like that echo "0 0 0" >/sys/class/scsi_host/host<n>/scan but it found only sda disk which is already running.. Using CentOS 5.5, x86_64.

On my C5 machine (a Dell XPS420) I have a 500Gb disk on the internal SATA controller. I also have a SiI3132 dual-port multi-device eSATA card. This is connected to an external SATA array of disks.

Hello everyone, Current host build is RHEL 6.2, soon to be upgrading. I'm in the process of mapping out a KVM/RHEV topology. I have questions about the landscape of storage pools and the instantiation of specific scsi_host IDs using virsh nodedev-create and some magic XML definitions. I'm grouping these questions together because the answer to one may impact the other. High-level goals: - fence off I/O by providing NPIV paths to VMs individually - provide each VM with a pair of paths to the same storage for re...

This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). This version rebased on Rusty's virtio ring rework patches, which has already gone into virtio-next today. We hope this can go into virtio-next together with the virtio ring rework pathes. V6: rework "redo allocation of target data"
