similar to: Boot from FC SAN CentOS 5.1 x86-64

Hello, I am trying to find out a best practice for a specific scenario. First of all I would like to know what is the proper way to set up multipath, who should care about it the host or the guest. Right now I have a setup where I have one multipath which sets my host to boot from FC SAN. I have another multipathed LUN in the host which is essentially a dm which I attached to a guest, however

Hi all! I need to compile de IBM Mpp-rdac driver in XCP 1.0 to use with the IBM DS4700 storage. Is there any way to do this? -- Rogério da Costa _______________________________________________ xen-api mailing list xen-api@lists.xensource.com http://lists.xensource.com/mailman/listinfo/xen-api

Hi list! I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for both ports, and boot the CentOS installer with "linux mpath". Installer detects multipathing fine, and creates mpath0 device for root disk. Installation goes fine, and the system boots up and works fine after the install from the multipath root device. After install the setup is like this: LUN 0 on

Hi all, I have problem with my servers. I use two of HP Blade Servers and RHEL 4.6 installed on them, and have IBM DS4700 connected to them. In those servers are running RHCS (Red Hat Cluster Suite) with GFS for handling Oracle Database. Yesterday, I had missing one partition from the storage, suddenly. I called IBM and they suggested to use RDAC. The question is, Why should use IBM RDAC for

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

I'm missing something. The purpose of NPIV (as I understand it) is to give a guest OS an HBA that it can scan, play with new luns, etc all without making changes to the physical server(s) the guest is living in currently. However, I can't find a way to either have the guest's XML config create the HBA or for the physical server to successfully GIVE the HBA to the guest. I can give

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

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

I've got my RAC cluster running pretty smoothly now (thanks again for all the help so far), but I only have single connections between the servers and the RAID array. The servers each have two Qlogic HBAs, and I'd like to find out if there's any reasonable way to implement multipathing. The platform is RHEL 3, and Red Hat's knowledgebase indicates that they strongly recommend

Hello, I will have two servers with fc storage. storage will be connected with two links to both servers ___________ ___________ | server 1 | | server 2 | -------------- -------------- | | | | -------------------------- | storage | -------------------------- on servers i will have multipathing enabled. storage has

Hi there, I have one server acting as a iscsi target running windows storage 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

Using CentOS 5.1, though with a few hours work I could update to 5.2.. I can install to SAN with a single path no problem but I'd like to be able to use dm-multipath. From the kickstart docs it seems this is supported but there is no information as to what the various options mean http://www.centos.org/docs/5/html/5.1/Installation_Guide/s1-kickstart2-options.html -- multipath (optional)

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

The following patches introduce support for multipath and cciss devices to the ovirt-node and node-image. Comments are appreciated. These patches assume that the 3 patches (2 node, 1 node-image) from Joey are all incorporated. Mike

All other patches from the sequence remain unchanged. Repost of patch 6 based on comments from Joey to follow. Mike

Dear all Sorry if it''s kind of off-topic for the list but after talking to lots of vendors I''m running out of ideas... We are looking for JBOD systems which (1) hold 20+ 3.3" SATA drives (2) are rack mountable (3) have all the nive hot-swap stuff (4) allow 2 hosts to connect via SAS (4+ lines per host) and see all available drives as disks, no RAID volume. In a

Hi Team, Is there any body got any experience on setting up a virtualized environment in which the vm's can access a fiber channel SAN storage connected to host? the host access the SAN through its own HBA, but the hba is not recognized inside the virtual machines. Please let me know the step to go through this. Regards -------------- next part -------------- An HTML attachment was

Hello all We are looking into ovirt for several weeks now and i have to say that it looks very promising. Our current environment is based on a lot off shell scripts and xen. We would like to move to ovirt but there are some things we would like to have working before moving. 1. using FC, san and clvm for storage 2. The ability to migrate virtual machines when we have to do maintenance on a
