• Could not see the iSCSI target in the adapters iSCSI software under Configuration details page

  Detailed description:

  After you add the IP address of the iSCSI target in the target iSCSI dynamic discovery Tab names can be seen under static discovery. But, iSCSI target is not considered as adapters iSCSI software tab Configuration details page.

  This iSCSi target is already mounted as a data store VMFS5 with some VMS on an another ESX which is part of the different ESX cluster in the same center of work data.

• The upgrade to ESXi 4.1 with storage iSCSI software to ESXi 5.5

  I intend to upgrade ESXi 4.1 with which I have attached to ESXi 5.5 iSCSI software storage

  I've updated all my guests who were on the SAN storage with no problems.

  I would like to know that if it there's nothing I should take care before I update the host connected iSCSI to ESXi 5.5, as for the hosts with SAN attached storage I made to remove the cables of SAN before upgrading the host.

  Also, if all known problems, you will be informed during the upgrade to ESXi 4.1 to ESXi 5.5 with iSCSI Software storage, please let me know?

  If there is no different process to upgrade coz in ESXi 4.1 I do not see this link ports of iSCSI vmkernel ports software iSCSI but I know in ESXi5.5 we have to or I just launch a procedure of standard upgrade via the Update Manager and everything will be taken care?

  Thanks in advance

  With ESXi prior to version 5, linking ports had to be done via command line. However, if it has been configured correctly, you should be able to upgrade to ESXi 5.5 (assuming that the host has not been previously updated since version 3). BTW. the last time that I disconnected the host of storage for an upgrade has been with ESX 3.0.

• Definition of adapters additional iSCSI Software

  My setup is two VMware ESXi 4.1 servers that are grouped together. I have installed software iSCSI adapter and installation on one of my servers in VMware ESXi 4.1. It works fine and I can access the two servers SAN.

  Now I want to create a second software iSCSI adapter. Is this possible? I tried, but were incapable of success.

  Any ideas on what I can do wrong?

  Thank you

  You will not be able to create more than one iscsi software. If you want to connect to a diiferent storage you can do using this iSCSI adapter.

• ISCSI software issues

  I think I'm loing my mind and I forgot a few basic things that if someone can update it please my mind that I can't find it in any documentation?

  (1) different iSCSI targets how can you use simultaneously with the initator of integrated iSCSI vkernel?  This is true for ESX 3.0 and 3.5.

  (2) if I run HBA iSCSI;  can I still use software iSCSI?  For some reason, I stuck it in my mind that I can't do this (it is hardware or software... can't do both at the same time).

  Thank you all!

  (1) 64 targets

  (2) use you software initiator or hardware initiator, not both

• iSCSI iSCSI Software adapter or Broadcom adapter?

  This is a bit of follow up a thread on a previous post. But I noticed that my BL490c G6 5 hosts have a software adapter and Broadcom iSCSI adapt. Although I have nothing under Broadcom cards.

  Is there a difference in performance between these two? In my head, material should be better than software, but it seems software as default.

  I found this KB, indicating he may be some Fiddlers involved to get ESX to use Broadcom cards, but is it useful?

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1025644

  The iSCSI SAN is a StorageWorks P4300 G2.

  The BCM5709 equivalent and can slightly reduce the amount of work the CPU has to do, but does not support Jumbo Frames.

  If you are network switches or a table do not support frames then using the capabilities of unloading of these NICs is good.

  If frames Jumbo is supported by the two switches and table so it is best to use the iSCSI HBA software.

• Add NIC initiator iSCSI Software

  Hello

  I already have a configuration iSCSI operating with a single NETWORK adapter on a host computer. I have a spare NETWORK on the host card, and I thought I could use it to increase the performance against the iSCSI storage. The storage is configured with aggregation of links (802.11ag).

  1 will be the two network cards increases the bandwidth against iSCSI, or it is used only for reasons of redundancy?

  2 is it better to use two vSwitches with a NETWORK card each, or should I use a vSwitch with two network adapters and ports link?

  3. can I just add the additional network configuration without doing anything to the initiator of the software, or do I have to disable-> the reconfig to networking-> re - activate the software initiator?

  I would also have a look at:

  http://virtualgeek.typepad.com/virtual_geek/2009/09/a-multivendor-post-on-using-iSCSI-with-VMware-vSphere.html

  (1) two NIC in a sandwich configuration balance the load pretty well.

  (2) I use a switch with two NIC, then you get annoying alerts for link redundancy and centralized management of the switch.

  (3) see the link. You need to set up an active / disabled and disabled / Active method for each load balancer vmkernel port. You will also need to link the port with the software iSCSI adapter vmkernel.

• When to use the ms iscsi software adapter

  When should I use a vmware disk or using ms iscsi initiator software to point to volumes?  People will usually switch to a certain size of disk?

  Hello.

  2 TB - 512 bytes is where you should start thinking about your options.  If you want a VMFS volume larger than 2 TB - 512 bytes, then you must watch the scopes or dynamic disk inside Windows options.  One of the biggest advantages of using the initiator iSCSI MS is that it is similar to the use of RDM - you can move them around much easier than with VMDK.  For me, it comes down more to the operation and management of the system to a particular size but.

  Good luck!

• Migrate to vDS for iSCSI Software

  So I'm going through the vDS migration guide, but I'm still a little fuzzy on how I need to migrate my VMKernel ports software iSCSI. Here is my setup...

  I have 4 hosting a test cluster. Two network ports are dedicated on each host for vSwitch1 which has a VMKernel port with an IP address in the 10.5.33.

  How can I disconnect from my software iSCSI initiator or migrate the IP address of a vSS to a vDS without a cause of a conflict?

  While add you ESX host service VDS, there is an option to add the console service & VMkernel iSCSI to the vDS. If you already add this particular vDS host, remove first the host of vDS.

• 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.

• 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.

• Link to maps software iSCSI NIC vmkernal and the vsphere client

  Hello

  IM playing with our VMware 4.1 hosts a Dell Equallogic PS4000E, connection

  So far, I have:

  Created ports VMkernal

  Apply adapters

  The iSCSI initiator enabled

  But apparently, I need to run the following command to bind the ports of iscsi software adapter:

  Add an esxcli swisscsi nic - n vmk # vmhba d #.

  Is anyway in the Vsphere Client?

  Hello.

  Unfortunately, there is no way to do it from the vSphere client.

  Good luck!

• find the number of map software iscsi vmhba

  Hi, im trying to write scripts for automation but I find on different server models the software iscsi adapter varies from vmhba32 to vmhba39

  Is it possible that I can find that number using powercli so I can put it as a variable to be used for another command later in the script?

  Thank you

  Forget the bug with iscsi.

  It's the derivation

  $esxName = 
  (Get-VmHost $esxName).StorageInfo.ExtensionData.StorageDeviceInfo.HostBusAdapter | where {$_.Model -like "iSCSI Software Adapter" -and $_.Status -notlike "unbound"} | Select Device

• Overhead costs with software iSCSI vs NFS?

  If you use NFS to store your VMS VMDK files, could say nothing about the CPU above for this, compared to the iSCSI Software?

  If you use the FC or iSCSI hardware, it seems, most of the work could be discharged at the HBA, but what about NFS that needs to be done in software? It will be easier that iSCSI from the Vmkernel doesn't have to manage the lower block level access?

  Hello.

  The difference is very small.  Check out the white paper of comparison of the performance of the Protocol storage in VMware vSphere 4 .

  Good luck!

• Software iSCSI or Broadcom HBA w/TOE?

  ESXi 4.1 loading on 3 Dell R710.  ESXi is picking up the 1 GB Broadcom 5709 as material hba, however nothing I tried helped me activate frames.  When I implemented the hba with frames and make a new analysis, he will not come to the MD3000i LUNS.  (The 3000i detects the hba and I added to the host in the iscsi handler... still no joy at the end of ESXi.  Also I configured ports on the 3000 to accept the extended frame).  If I leave the mtu to 1500, everything works well under hardware iscsi.

  When I use the software initiator with the same NETWORK card, I can activate frames.  (Documentation is ESXi confirms that for the Broadcom, it supports IPv6 and jumbo frames, but you can't blame a guy for trying).

  My question: which would give better performance?  Should I use the material hba without jumbo frames to reduce the load of iscsi, or configure software iscsi with frames?  If I understand correctly, the iscsi software has been greatly improved if I'm not really sure which way to go.

  (I posted this question at the end of another thread and received no bites so I thought I would like to transfer as a new question.)  I apologize.)

  As you discovered, you can really change the MTU on the HBA Broadcom adapters.

  Performance is always difficult to answer.  Of course, the biggest advantage of Broadcom cards is improvement in the effectiveness of the CPU.  There are benefits to this.  Also, realize that the initiator iSCSI ESX and initiator of Broadcom can saturate a link of 1 GB for block sizes more that are useful, even in the absence of the frames.

  So if you are looking for CPU efficiency, for the most part, the block sizes, the Broadcom card will use less CPU host for the same flow as the frames with the initiator of ESX.

  If you are looking for a pure flow, both can fill a wire for large block sizes, and which does not change much with the introduction of jumbo frames.
