• Migration of the iscsi initiator software to hardware initiator on 2012 Hyper-v cluster.

  Hello

  We have 10 blades x M620 with Broadcom 10gig 57810 M1000e CMC card dedicated for iSCSI Equallogic PS 6110 San.

  Currently software used on cluster hyper-v Windows 2012 connect SAN PS6110 iscsi initiator.

  150 VMS are in production on 15 CSVs.

  We want to change the initiator of the software to the hardware on all our existing blades without CSV output.

  Is it possible on hyper-v cluster 2012 to have 5 blades with initiator software and remaining 5 blades with hardware initiator with same CSV cluster?

  If coexistence of initiator software and material as possible through hosting then I can apply this change a bit on our 10 blades without cluster downtime.

  Hello

  What version of FW EQL do you use?

  Yes, it is possible, however a couple of updates warn first.

  1.) install the latest firmware / boot code and driver for Broadcom cards.

  2.) put the node into maint mode then you can disconnect the SW iSCSI provenance and sign in using the HW iSCSI adapter.

  3.) do not try to do it with an active node / online.

  The advantage of the HW iSCSI adapter reduces the CPU Overload, if you are maxing out the CPU not now, do not expect a large increase in performance after HW iSCSI card.

• Left and initiator ISCSI hardware

  Hello

  I am wanting to install a Lefthand P4500 ISCSI SAN with 3 x ESXi4 servers and use hardware ISCSI initiator. Now, my question is I plug the adapter of material directly into the ISCSI storage or I can plug it into a switch that connects to the storage as with the ISCSI Software initiator?

  Thank you

  You can do both. I would use a switch (or more) to take advantage of multiple paths.

• iSCSI hardware vs software adapter

  Hey all -

  I'm trying to figure out a vMotion (the issue being that it has essentially stopped working). A lot of what I read pins vMotion storage problems, so I start there. Anyway, while I was stung by storing a question occurred to me:

  If you have natachasery that can handle unloading iSCSI, iSCSI Software adapter should be disabled? that is, you should only use the adapter software if you do not have the ability to discharge with your physical network adapters, correct? Also, someone a hunch as to whether or not there was no disturbance, if I disable the software adapter (as far as LUNS are all showing on the HBA hardware)?

  Thank you

  -Chris

  It is a good question. I had the same setting up my storage. OK he think like this: If you have two ports on a 10 GB of a PS6010 controller, you technically "two" paths to an ESXi host, because each port has an IP address. You can see what path is related to IP in the section manage paths, in the target box (or below the paths section) say now you have two members, and both bear the same characteristics, you have now four active paths (e/s). It's really whatever the physical connection outside of the host. You might have a physical SFP + NIC and it would record two paths since you have two addresses targets, even if you have a "physical" path Kinda like a-< split="" if="" you="" want="" to="" think="" of="" it="" like="">

  All the below assumes that you have a dedicated set of switches, links dedicated to each Member and each switch with failover best practices in place. It is recommended that you isolate your network from your normal network storage. If you try to share the EQL storage with the normal operation of the network, you add an unwanted complexity.

  What you need to do is to make sure that your VMkernel iSCSI denomations are linked up to the the right vmnic. Under your EQL iSCSI vSwitch properties make sure you that you wanted to make a replacement of the switch for vmnic assignments (put the host in maintenance mode in order to test everything without killing any connection VM):

  • Click your vSwitch properties, select iSCSI0 and press 'change '.
  • Tab grouping of NIC, be sure that the order of failover is selected for "substitution vSwitch order of failover
    • Active adapters: vmnic 0
    • Unused cards: vmnic 1, vmnic 2
  • Follow these steps for the other two iSCSI designations, ensuring that you have only one per group of iSCSI ports.

  Something I noticed is that you don't have a group of dedicated port of vMotion. This should be done just for the sake of consistency, but does not mean that you must burn a port just for vMotion. In my environment, the port assignment looks like the attached screenshot (vSwitch assignments.png). Both of the vmnic are assigned to my group of ports of vMotion.

  Finally, make sure that MEM has linked the vmnic associated with iSCSI (above) to iSCSI Software adapter (vmhbaxx) traffic. You may want to just start over and delete the vSwitch, rerun installation MEM everywhere and then perform the steps above. But I need to show you what was going on until I told you to catch the vmnic and target the vmhba for the iSCSI Software initiator.

  At the end of this, you will have a configuration like this:

  • NIC teaming override for a vmnic for each port group.
  • All THE vmnic which is used for iSCSI communication RELATED to iSCSI Software adapter vmhba (i.e. vmhba36) using the 'config' MEM Setup Wizard
  • All the paths in your storage space must be Active (e/s)

  Does make sense? Joined a MEM so cheat sheet. It is based on the goal. I guess I call the sheet when I need to set it up in a hurry. You can see that Dell is too attached.

  Hope that helps.

• An iSCSI hardware network card can be used for ordinary IP traffic?

  If I have a hardware iSCSI HBA card, it's a NIC where ESX could unload all iSCSI handling to, this card could be used for something other than iSCSI or it will only be dedicated to iSCSI traffic?

  In other words, for example, could vMotion or VM traffic more than NIC go too? (It obviously wouldn't be a good thing to do, but I'm curious to know if it is possible).

  If you mean an HBA full offload iSCSI, then the answer is no. The HBA actually operates all the management of the TCP/IP Protocol and presents the iSCSI LUNS to the host as direct-attached storage. If you go to the QLogic website, you can find a few whitepapers that explain unloading as well as certain patterns showing the CPU load with a THAT HBA full offload compared with active TOE NIC (such as HP/Broadcom).

• MD3000i documentation hardware initiator?

  We have a new MD3000i and Server Blade M1000e.  The blades have the Broadcom 5708 NIC Netxtreme II, which can be used as HBA is not required for MS SW Initiator.  Documentation on setting up the MD3000i only talk about configuration he and MS SW Initiator.  Anyone know if there is no recent docs who speak using an initiator of material instead of the MS SW Initiator.  I don't think I need MS SW initiator on the server at all?

  We'll run our LAN 2 ports and 2 ports for our MD3000i but hoping does not need MS SW Initiator.  The blades starts from its local readers and access to MD3000i storage.

  Thank you

  
  

• the iSCSI hardware recommendations

  I just had one Digital EN104L + B (below) die on us after less than two weeks of service, and he was SLOOW before he fell.  Our problem was along the lines of this type problem:

  http://www.sansdigital.com/index.php?option=com_kunena & Itemid = 190 & Func = View & ID = 1568 & catid = 10 #1568

  Before that, we had openfiler which worked well, think back to that.

  However, we liked that digital WITHOUT was all in a single unit and that he didn't need that a host like openfiler server does.

  are there units iSCSI in the meantime 1K - 2K like this don't suck?

  http://www.sansdigital.com/elitenas/en104lplusb.html

  

  It hasn't is usually very little tested differnce between iSCSI and NFS. The simplicity of NFS WINS for me.

• Can you point me to documentation or explain how to configure the iscsi hardware in vCenter?

  I have two HBA ports in two of my servers and a switch dedicated for iscsi. What are my next steps after that I get ready to go with my LUNS carved MSA20212i HP? What should I do with vCenter? I know I'm going in the storage area and search for new LUNS, Philippe isn't a step forward that?

  Hello.

  The best documentation to use will be Guide de Configuration of iSCSI SAN.

  Good luck!

• Please help me with iSCSI software initiator setup in ESX.

  Greetings,

  I have a DELL MD3000i SAN with two controllers. Each controller has both for the multipath iSCSI network interface cards.  I've always used CF so I'm a little nervous in the implementation of iSCSI network on ESX. Please help me.

  Controller 1 port 1 is the IP 192.168.253.2

  Controller 1 port 2 is the IP 192.168.254.2

  2 1 joystick port is the IP 192.168.253.3

  2 2 joystick port is the IP 192.168.254.3

  I have Setup VLANS on my level 3 for switch vlan 253 and 254.  IP addresses are 192.168.253.1 and 192.168.254.1 respectively.

  My goal is to set up a fully redundant connection with failover support, but I can't enter the network on ESX configuration.

  I intend using two network adapters in an active / standby (one active NETWORK card on a VLAN, put on hold for the other and vice versa) configuration.

  Can someone please tell me exactly what to do to ensure the fully redundant connectivity?

  Thank you in advance.

  Yes. This look is good so far.

• Hardware iSCSI adapter connection problems

  HP DL385 G7 with 2 HP (Broadcom) NC550SFP Dual Port 10 GB adapters. ESXi 4.1 U2

  You try to bind material load NC550 adapters to the good network card.  When I list of the HBA association and the NIC.

  esxcli - list of server servername swiscsi vmnic vmhba d #.

  It displays the physical NETWORK card bad example vmnic0 which is a 1 GB card NETWORK configured as the VM network and network management

  I had previously assigned iSCSI Software for the two vmnic adapter in the NC550SFPs.  However when I list the cards for the iSCSI HBA software, it lists each NIC in the system.

  Tried to simply bind the correct physical NIC to the iSCSI HBA hardware

  esxcli - add a server servername swiscsi nic - n vmkx d vmhba #.

  where vmkx is the physical NIC for the NC550 and the vmhba # is the HBA for the NC550

  and it failed with: failed to add a network card

  Attempted to delete the incorrect association

  esxcli - server servername swiscsi nic remove - n vmkx d vmhba #.

  where vmkx is the nic which was displayed in the list for hba named vmhba #.

  and he returned: NIC is not bound

  Do not know where to go next...

  Hello

  In addition my property would be to disable the iscsi Software initiator - you want to use only the hardware iscsi adapters, don't you.

  Mixing software and hw adapter is not recommended method here, as far as I know.

• Jumbo frames based on VI3 3.5 / iSCSI initiator of material?

  Hello

  Apologies if this has already been posted. If so please point me to the thread, but I just wanted to confirm with you guys jumbo frames based on VI3 3.5.

  As much as I know frames are not taken in charge for software iSCSI but it is supported for the hardware iSCSI initiators but please correct me if I'm wrong. Now what hardware initiator you recommend for jumbo frames?

  Thanking you in advance,

  Saludos,

  In ESX 3.5, 10 gigabit Ethernet and jumbo frame are NOT supported on storage traffic (for example, the software initiator).

  In ESX 4 are supported.

• As Raw - Microsoft iSCSI initiator

  Buenas tardes,

  Me han planteado than already usar el software Microsoft iSCSI Software Initiator connect para a las mi san LUN y as in su lugar connected con estas LUN mapeando una unidad RAW directly con VMWare esxi 4.1. Según el performance read hey're mejor, pero no estoy del todo convencido gente are only también he read as lo desaconseja. Estas Lun´s contienen UN ficheros / newspaper databases datos por lo as el performance are important.

  MUCHAS gracias,.

  Saludos.

  Hola SistemasLTK,

  Esta esta dada debido mid-week has used el initiator iSCSI dentro del operating system of una MV, estara utilizando los puertos of Red experience para el trafico maquinas office in use puertos experience vez para el trafico iSCSI.  In este sentido tienes back options:

  • RDM use para conexion utilizando red iSCSI LUN.
  • Dedicar red para el trafico dicha MV iSCSI puertos, y seguir el initiator iSCSI dentro to MV using.

• Error in adding an iSCSI LUN - use software iSCSI initiator...

  Hi guys,.

  I can't add an iSCSI LUN to my host ESX4.0. It is the iSCSI Software initiator that is activated and I can see the LUN after I launch a new analysis.

  While adding the LUN as a data store, it throws me an error, please find the attached for the snapshot file.

  The real question is if I add a lun iSCSI and then remove it and again try to re add it whether or nor the old signature are found that do not readd it.

  Is there a command that I can use to remove all the LUNS already assigned and delete it existing signatures.

  Let me know guys if the above is not clear.

  Kind regards

  Use fdisk to create a partition and vmkfstools - C command to format the partition as VMFS. You use a supported storage array?
