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

Hi list, I have a call file as following and it works. But, I don't really understand its mechanism. The SIP/voipbuster is a sip trunk which I set up in freePBX with voipbuster account. And 2874 is one of my extension which was assigned to x-lite client. When I place this call file in outgoing folder, it is able to dial out my home phone at 001xxxxxxxxxx. However, the Dst in call logs show

Hello, I have asterisk 1.2.9 running on a Debian sarge server, my outbound dial plan looks something like this: [outbound-longdistance] exten => _91NXXNXXXXXX,1,Dial(${OUTBOUND1}/${EXTEN:1}) About every other outbound call we make, we get the 'you must first dial a 1' message from our phone provider. It only seems to happen every other try if we try to make multiple out bound

Guys! I have one fiber channel IBM storage (10T) and 8 HP Proliant servers with 32G of RAM on each and 1 HP with 4G of RAM. My question is: * How to use the same storage (block device) with all my different virtualization 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

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

I've configured 6 bricks as distributed-replicated with replica 2, expecting that all active bricks would be usable so long as a quorum of at least 4 live bricks is maintained. However, I have just found http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/ Which states that "In a replica 2 volume... If we set the client-quorum

Hi all, I found a article about Hyper-V virtual Fiber Channel, I think this will make Failover Cluster work if KVM has the same feature. http://technet.microsoft.com/en-us/library/hh831413.aspx Hyper-V uses NPIV for virtual Fiber Channel, I have read some article about KVM NPIV, but how can I config it with libvirt? Any body can show me some example? On Wed, Aug 14, 2013 at 2:33 PM, Timon Wang

I don't think I've seen this with CentOS 6 or 5, but I had to repair an external RAID box this morning. The server, running CentOS 7, has an LSI HBA card in it, and it's presented to the system as /dev/sdb. I shut off the RAID controller, powered it off, did the repair, then plugged everything back in (that includes the two fiber cables and the ethernet), and brought the RAID back up.

Had a problem starting Oracle after expanding an EMC Metalun.

Thanks. I have read the link you provide, there is another link which tells me to pass a NPIV discovery lun as a disk, this is seen as a local direct access disk in windows. RAC and Failure Cluster both consider this pass through disk as local disk, not a share disk, and the setup process failed. Hyper-v provides a virtual Fiber Channel implementation, so I wondering if kvm has the same solution

Hello, In AFR we currently allow look-ups to pass through without taking into account whether the lookup is served from the good or bad brick. We always serve from the good brick whenever possible, but if there is none, we just serve the lookup from one of the bricks that we got a positive reply from. We found a bug? [1] due to this behavior were the iatt values returned in the lookup call

Hi Sanjoy: >> Now in the above CFG %val can be folded to 10, but in reality you need >> a PHI of 10 and 20 Quick answer: folding %val to 10 is OK, but, I would prefer it to be 'undef' or even catch it in the verifier as it is a programmer/frontend error. Details are in the second half of my reply. I would like to start with the thought experiment you suggested, as it might

Hi Sanjoy, >> I'm not familiar with fiber-type APIs, but I assume fiber_fork is like >> setjmp, in that it can "return twice"? Yes, user-mode stack switching API are somewhat similar to setjmp. Here are links to a doc page and implementation, just in case you are curious: http://www.boost.org/doc/libs/1_59_0/libs/context/doc/html/context/context.html

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

Please forgive the (almost?) OT post. (and the fact that I need a clue-bat) We've got a situation at one of our sites where a construction crew is likely to dig up our conduit which houses some data fiber and one pair of fiber used to tie a Definity 3gsi at a small office building to the rest of the phone system (school district). We're using a pair of Aeronets to the data network stays
