• 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!

• 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

  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.

• iSCSI and adapter NC550SFP

  Hi all

  I have adapters HP NC550SFP with ESXi 4.1 for an iscsi (10 G, control flow and frames configured) network.

  My configuration is up to now using the "iscsi software map" in vmware... because I see no support for adapter hardware iscsi for these cards. My questions are:

  1 the NC550SFP is supported by a hardware iscsi adapter?

  2 should I worry used with 10Gig iscsi software adapter?

  Thanks for your time... I'm a newbie to iscsi here... so I would like to do things properly before putting them on the prod!

  Glenn

  1 the NC550SFP is supported by a hardware iscsi adapter?
  2 should I worry used with 10Gig iscsi software adapter?

  1. I see iSCSI on the plug on HP, but no confirmation that it is a hardware iSCSI HBA.  It should be appear under storage adapters if she supports the iSCSI hardware.

  2. I don't think you should be concerned.  ISCSI HBA hardware will take off the part of the processing load and overhead of off the VMkernel (CPU and memory).  But you can see the small difference with the new processors and memory that we have in the servers today.

• 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.

• initator iSCSI Software

  Hello

  is there a way to activate the Initator ISCSI software on a host ESXi 4.1?

  I was playing arround with the orders-Get /-Set-VMHostHba, but it dosen´t work.

  Another problem is that I identify the number of the vmhba cause I m using models of different hardware, I tried the following command:

  $iscsi = get-VMHostHba - VMHost $vmHost | where {$_.} {Model - like "adapter software iSCSI"} | Select device but $iscsi always returns "null".

  It would be great if sombody can help me this two probs bit.

  Thanks in advance

  Odd, works for me.

  Have you made a

  Get-VMHostStorage $vmHost | Set-VMHostStorage -SoftwareIScsiEnabled $true
  

  to enable iScsi?

  What is this returns everything that said "IScsiHbaImpl"?

  Get-VMHostHba -VMHost $vmHost | %{$_.GetType().Name}
  

  Do you see an HBA with a status of "independent"?

  Get-VMHostHba -VMHost $vmHost | Select Name,Status

• 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.

• iSCSI HBA adapter

  Been having a lot of problems with a repressive IBM X 3650 M2 and its compatibility with the UEFI.  The problem I have now is that one does not see the storage and was curious to know if HBA will really hurt.  I know that sounds like a stupid question, but it's the only thing I have left.  I checked, double checked, m and triple checked all the settings and they are correct.  Swapped cables, exchanged ports and after a new analysis to show anything.  The other adapter is fine and the only other thing that I've been swap cards around.  Did not have to open the box.  Are there other things I can try to see why this HBA adapter can not see the storage?  It pings very good also.  The wuggestions are welcome. Thank you

  Perry

  Is there a firewall between you and the iSCSI storage?  Using CHAP?  Have you checked that the initiator is set up for CHAP authentication on the storage side?  There could be lots of things, even a HBA bad as you mention... but if it can ping successfully I guess it's a problem of configuration somewhere.

• 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.

  Kind regards

• 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.

• 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

• 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.

• On broadcom BCM57800 10 Gb nic and iscsi

  Hi guys,.

  I have a 5.1 with 1 NIC broadcom NetXtreme II bcm57800 esxi server and would use my storage via iscsi.

  This adapter support iscsi off load but I do not understand if it is mandatory to add "iscsi software adapter" too esxi or not.

  Thanks in advance.

  Hi gianlucab,.

  Only, you would use the iSCSI Software adapter if you need the kernel ESXi itself to perform iSCSI operations. You would use this with Ethernet adapters that do not support iSCSI unloading.
