Hi Everyone I am looking at setting up a File Server that uses ISCSI storage. It is the first time I have done this, so I am wanting to get peoples thoughts on whether for CentOS systems you should use Hardware based ISCSI HBA's? If so do I need to be careful about what HBA I use ? Currently I am looking at purchasing a Dell System using Broadcom ethernet cards/ ISCSI HBA. From google searching it seems QLogic HBA's are quite popular ? Any suggestions or experience you can offer appreciated. Have a nice d...

...servers simultaneously? I have 2 open source Xen with CentOS 5.4, 2 VMWare ESX, 2 Citrix XenServer, 2 KVM powered by Ubuntu and 1 Debian exporting the IBM storage to a SAN via NFS/iSCSI/CIFS... And, I have more open source Xen servers using the same storage, but via NFS instead via fiber channel (HBA). So, how to store the virtual harddisks on a repository visible by all flavours of virtualization technologies? Is there some kind of cluster file system compatible with CentOS, ESX, XenServer, Ubuntu and Debian out there? Or... do I need to divide the storage, for example, creating LUNs for...

...upported, but it looks like I can't wait till then, got lots lots of questions from both the bugs and mails. So here we go. The document tries to summary up the things about NPIV that libvirt supports till now, and the TODO list. Feedback or suggestion is welcomed. 1) How to find out which HBA(s) support vHBA For libvirt newer than "1.0.4", you can find it out simply by: # virsh nodedev-list --cap vports "--cap vports" is to tell "nodedev-list" only outputs the devices which support "vports" capability, i.e. support vHBA. And also...

Hi, When I want to use NPIV for a FC HBA in my Linux machine, I got the below error msg in virsh: virsh # nodedev-create /home/kvm/vHBA.xml error: Failed to create node device from /home/kvm/vHBA.xml error: internal error Parent device scsi_host20 is not capable of vport operations I checked the /sys/class folder for my HBA device tha...

I want to configure my zfs like this : concatination_stripe_pool : concatination lun0_controller0 lun1_controller0 concatination lun2_controller1 lun3_controller1 1. There is any option to implement it in ZFS? 2. there is other why to get the same configuration? thanks This message posted from opensolaris.org

Hello, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

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 vi...

...orkaround around this? Any better way, forking virsh execution somehow? Could anyone explain why this is creating a deadlock in the first place? Isn't libvirt multithreaded? Thanks for the help!

Hi. I'm looking at a qlogic qle2462 hba for my dl360 g5. The thread http://www.mail-archive.com/freebsd-stable@freebsd.org/msg99497.html mentions a deadlock when system is loaded. Has this issue been resolved? Are there other PCI Express hba's which are known to work with freebsd stable and dl360 g5? -- regards Claus When lenity a...

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. T...

Hi all, this patchset implements an emulation for the megaraid_sas HBA. It provides emulates an LSI MegaRAID SAS 8708EM2 HBA, ie presenting to the guest a virtual SCSI adapter. Internally it is using aio for read/write requests and either SG_IO or SCSI command emulation for everything else. The reason for choosing the megaraid_sas HBA and not, say, implementing a vir...

I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2s,

...age server r2 sp2 and the other server is running centos as an initiator. They are connected to a switch over a 1Gbit ethernet connection. the target is a Dell NF600 and the server running centos is a Poweredge R900. We want to move this configuration to a FC based installation using a Dell QLE2462 HBA (this is the hba we can get here). So, i would like to ask before i make a mistake..... :) If I purchase an ethernet fiber switch and add a Dell QLE2462 HBA to both servers and connect the servers to this ethernet switch, will I be able to use this configuration as iscsi target/initiator? will i...

Hi I recently installed some hba's into a bunch of these 585's as they are forming a RAC cluster - previously to this they were all using DAS without issue. After the qlogic cards were installed i reinstalled the OS and now once installed the OS will not boot - the box just reboots continuously, it does not even appea...

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 notice this problem with CentOS...

Does anyone have any experience with Emulex HBA cards (LP10000) using OCFS2, Linux AS4 U4 x86_64 AMD? I'm trying to find out whether this is a verified combination, if anyone has successfully used it. I have that hardware/sofware combination, and am experiencing stability/performance/panic/hang issues with OCFS2. -------------- next part -...
