similar to: How can I get the HBA and disk devices info out-of-band?

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

Hi all, I manage to create a VM (slackware image) and hide the PCI device (qlogic HBA) from Dom0 to DomainU. Now the Dom0 cant see this HBA and the ''xm list -l'' shows this pci device under the DomainU. But how can I do some scsi inquiry or check if this PCI device is visible to the DomainU from the DomainU''s console. Any help? Thanks and regards Ashit

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 list, I have the choice to use RHEL4 or Centos4.x on a Dell PowerEdge2850 who is linked to an AX100 storage system. My question is: does the QLA200 (the pci fiber channel card) driver will work on CentOS 4.1 . For now the card is listed like this on CentOS 4.1: --- #lspci 09:04.0 Fibre Channel: QLogic Corp.: Unknown device 6312 (rev 03) --- What kind of modification must/can I do to the

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.

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 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

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

I apologize in advance as this is not really at CentOS specific issue, but I don't know where else to turn. We are configuring some Dell 1850s for a customer, and they have all been configured with a QLogic dual channel HBA. But no storage has been (or will be in the near future) attached to these HBAs. During the boot process (both for the kickstart and after the OS has been

I wanted to post this in case there is a real bug here. The system this is on is running Debian Etch with the Xen packages from Debian Unstable (currently 3.0.2+hg9697-1). I am running all packaged software so this is probably slightly out of date. This is on an HP DL320 G4 with a Pentium D 930 processor. I tried unloading and reloading the qla2xxx module, but rmmod reported it in use, however

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 -------------- An HTML attachment was scrubbed... URL:

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

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 and cruelty play for a kingdom, the gentler gamester is

Dear List Users- IHAC planning storage layout and is looking for the following MAX_LUNS size limit on RHEL 3.0 and 4.0. Details are below. Customer database size is estimated to grow to 5 TB and worries that they will not be able to present enough devices to the system if used with EMC powerpath and RHEL 3.0 max_lun limitations. I have advised on using OCFS or ASM as this is a 10g Database
