Automatically detecting LUNs without a reboot
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

Getting "unknown device type" when attaching NPIV (vHBA) to vm
Hi, I'm trying to attach a host FC HBA to VM (NPIV). Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA. I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device. Also, when trying to attach the device manually as a live device - I get:

[PATCH] virtio-scsi: Fix hotcpu_notifier use-after-free with virtscsi_freeze
vqs are freed in virtscsi_freeze but the hotcpu_notifier is not unregistered. We will have a use-after-free usage when the notifier callback is called after virtscsi_freeze.

[PATCH] Staging: hv: storvsc: Show the modulename in /sys/class/scsi_host/*/proc_name
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').

Re: Getting "unknown device type" when attaching NPIV (vHBA) to vm
Thank you for your reply, I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc.

SATA hotswap
Hi all, I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does 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

How to map ata#.# numbers to /dev/sd numbers?
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. Now occasionally I see something like this in my logs ata7.01: exception Emask 0x0 SAct 0x0 SErr 0x0 a ction 0x0 ata7.01: irq_stat 0x00060002, device error via D 2H FIS ata7.01: cmd

Storage Pools & nodedev-create specific scsi_host#?
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

[PATCH 1/4] add scsi-target and IO_CMD_EPOLL_WAIT patches
This includes two kernel patches, scsi-target and IO_CMD_EPOLL_WAIT. The former is a modified version of the scsi target infrastructure in mainline. The latter enables applications to handle AIO and non-AIO fds in the same loop. blktap uses the different patch, AIO event queue patch for the same aim. The IO_CMD_EPOLL_WAIT patch will be merged into mainline (and the AIO event queue will not) so

[PATCH V6 0/5] virtio-scsi multiqueue
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"

[PATCH 07/28] 53c700: improve non-coherent DMA handling
Switch the 53c700 driver to only use non-coherent descriptor memory if it really has to because dma_alloc_coherent fails. This doesn't matter for any of the platforms it runs on currently, but that will change soon. To help with this two new helpers to transfer ownership to and from the device are added that abstract the syncing of the non-coherent memory. The two current bidirectional cases
