similar to: Virtualization of Fibre Channel?

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

Hello I''m a newbie here so please don''t laugh at me... I plan to setup several (4) physical servers to run xen virtualized OS-es (in example web servers). What I need is that those virtualized OS-es must have simultaneous access to disk storage physically created on FC array. I read that this could be done by OCFS or Lustre file system but my question is: how virtualized

Hello, I have been looking around all day and lot''s of things are being thrown at me such as npiv and vscsi and such. I have an HITACHI,DF600F SAN which goes via two switch fabrics and plugs in to the dual port Qlogic HBA on the server(s). I have 4 Dell 2950''s at current which are under-utilised. I want to buy new 2xR710 and consolidate these 4 servers to a single physical

For quite some time I?ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It?s time for me to replace my hardware and I have a new R720XD that I?d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I?m doing

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Hi, I have a host which is connected to SAN via single Fibre channel HBA (qlogic). I have several LUNS assigned to this (sdc, sdd). I added another single port HBA to this host. I can now see two world wide names. Now the confusion is which world wide name does sdc and sdd is/was using. scsi_id -g -u -s /block/sdc only gives wwid but I need the wwn for sdc and sdd. Thanks Paras.

I''ve compiled the 3.0-devel version on SUSE Linux 9.3. The ony problem is the qla2300 driver, which will not start all correctly on boot. So i cannot see other partitions than sda. --------------------------------------------------------------------------------- QLogic Fibre Channel HBA Driver ACPI: PCI Interrupt 0000:04:02.0[A] -> GSI 24 (level, low) -> IRQ 185 qla2300

Hi, I just deploy the ZFS on an SAN attach disk array and it''s working fine. How do i get dual pathing advantage of the disk ( like DMP in Veritas). Can someone point to correct doc and setup. Thanks in Advance. Rgds Vikash Gupta This message posted from opensolaris.org

CentOS 6.4 (amd64) stock kernel. HBA FC Accusys ACS 63200NT I built the driver from source, insmod activates the device and I can see the 24 TB storage volume via 'parted --list' I have created a XFS files system and mounted it under /srv/ Where do I need to install the driver in /lib/modules/ ... directory tree so that it is loaded automatically when the system boots? TIA, -- Arun

In waiting, I tried CentOS 8 which was an even bigger bust. I wiped that clean and tried again with Fedora 31. Same darn error "Could not create Target in configFS". Anyone??

I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4). More details: Some years ago I installed a NAS unit from Exanet which consists of 2 rebadged IBM x3650 head nodes and a couple of Xyratex disk shelves with a total of 96 TB of raw disk, connected by fibre channel. The operating system is based on CentOS 4.4, but is modified, and runs a

I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

The ZFS crew might be better to answer this question. (CC''d here) --jc William Yang wrote: > I am having issues creating a zpool using entire disks with a fibre > channel array.

Hi there, I've installed a Qlogic HBA in a 4.8-STABLE machine and I'm able to present LUNs to this machine from an HDS array and use them. That all works perfectly. However, the only time I pick up new LUNs is on a reboot. Seems like I should be able to rescan the fabric and pick up new LUNs, but there doesn't seem to be a way to do this. I tried camcontrol rescan, but that

Hi, I am trying to compile kernel 2.6.9-11.EL from kernel-sourcecode, and need the Compaq cpqfc HBA driver. I see the code for the driver under drivers/scsi but when I do a "make menuconfig" I do not have the option to select it. Any ideas on how I can get it to show up? Thanks. --

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not

Hi all, i want to virtualize an existing Centos 5.x machine (intel xeon, 64 bit OS, Qlogic HBA) into a vmware 3.X VM that will not be connected to the SAN (hence no need for the HBA drivers). So i googled a while and found this link: http://virtualaleph.blogspot.com/2007/05/virtualize-linux-server-with-vmware.html However the link is quite old and I wonder if anyone here has done such conversion

Hello, I have IBM Storwize V3700 storage, connected to 2 IBM x3550 M4 servers via fiber channel. The servers are with QLogic ISP2532-based 8Gb Fibre Channel to PCI Express HBA cards and run Centos 5.10 When I export a volume to the servers, each of them sees the volume twice, i.e /dev/sdb and /dev/sdc, with the same size. Previously I have installed many systems with IBM DS3500 series of

Very strange behavior, been banging my head against the wall on this one too. It works fine on CentOS 4.6, the behavior is when the driver loads the bus is not scanned or at least the devices that are exported are not detected. (they are detected in the HBA bios no problem). If I issue the qlogic bus scan command it doesn't get anything back either. If I manually add the devices with

Hi - We have had 3 rather major occurances of ext3 filesystem corruption lately, i.e. so bad we couldn't event mount, and fsck didn't help. I am looking for pointers, that could help us investigate the root cause. In general... We are running RedHat WS 3 Update 6, 2.4.21-40.2.ELsmp or 2.4.21-37.ELsmp We have a small SAN system that looks like this
