• initiator iSCSI on a Virtual Machine?

  VMCommunities,

  I'm having a problem running iSCSI on a virtual machine, so I can connect to the shared storage.

  Usually we do this on physical servers connected to the switch and it works without a problem, because we are able to ping these IPs private using the NIC second servers but within the Virtual Machine, we can't ping these IPs so, unable to connect to the shared iSCSI storage.

  When I add a new NETWORK adapter in the virtual machine itself give an IP 192.168.x.x (identical to the iSCSI network) it does not ping.

  What should I do to connect to the iSCSI network so I can use the iSCSI initiator?

  Thanks guys/girls

  Security issues would be the same if the iSCSI target/LUN that you connect was local storage... Usually you can not present a target/LUN iSCSI on a server operating system (like Windows) and present it to the ESX/ESXi hosts... I guess you follow smart (as close as possible) security practices... Yes? In production environments, it is not uncommon to have berries iSCSI (or berries SAN) on their own range/IP subnet. Restrictions on traffic in just this subnet would help eliminate unauthorized access... Even with a VM connection (directly), you should be fine... Make sure you have the guest OS patched for security vulnerabilities and other...

• initializing iSCSI SAN in VMWare Workstation 9

  Hi all!

  I created an iSCSI Target (Debian Wheezy) and an iSCSI Initiator (CentOS 6). Installation of netinstall (of CentOS) on eth0 to LUN0 on eth1 worked very well. Adjusted BIOS on VMWare to boot from first e1000. At startup, the operating system tries immediately PXE boot, iSCSI not...

  Any big brain here know what I'm doing wrong? I got about 16 hours sunk trying to develop this project, so any help would be appreciated! Thanks in advance for your time!

  Here is the answer to my problem: VMWare Workstation 9 does not support iSCSI boot.  It requires 'PXE chainloading', where a gPXE (or iPXE), PXE loads image gives VMWare PXE allows to start an iSCSI target.  Here are some valuable pages, I found on the subject, even if none show my specific "PXE boot CentOS of Debian iSCSI in VMWare Workstation 9"... guess I am the only one to write this tutorial!

• Beginners Overview: ESX to an iSCSI SAN servers

  Hello

  I hope I have the right section of the forum to do this, basically

  I'm trying to understand how VMWARE ESX server (3.5 if it is one)

  the difference) would connect to a SAN and what benefits it would be

  provide.

  Apologies if it's really basic, I'm new to both without and VMWare

  ESX so I'll try to understand all the concepts, I tried reading

  the articles, but they are a little dry for me.

  As I understand it, installing it would be something like

  this:

  Physics:

  ESX Server & gt; initiating hardware iSCSI (does not support

  (software?) & gt; cable network & gt; Turn on SAN & gt; Drive auto.

  Logic:

  Something like the creation of a LUN on the SAN itself (via the SAN web page) then use

  customer of VI to point to for a data store? Or is there some control of ESX?

  It would make sense that images of OS VMWare store customers

  on local disks to the ESX Server, so they start from all drives, in which case the SAN is down, then

  have the discs on the virtual machines stored on the SAN? Or will keep you

  everything about the SAN outside the ESX itself, which could at least

  remain separated from the SAN?

  Any help is appreciated.

  The main reason to use SAN storage is to provide shared storage so that you can take take advantage of features order higher than VMware provides as vmotion - the ability to move a running virtual machine form an ESX Server to another with no downtime for users of the virtual machine - DRS based on vmotion allows ensuring that the vms system receive the memory and cpu resources , HA that allows the virtual machine restart on another ESX Server.

  The physical scenario you describe needs to be corrected ESX and ESXi, they built insoftware intiators so you don't have a hardware initiator need - but if you choose to use a material to ensure that it is in the HCL - http://www.vmware.com/resources/compatibility/search.php

  This document will give you information on the how and why of using SAN storage - http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_iscsi_san_cfg.pdf

• Time synchronization problems ESX 3.5 U3

  Hello

  I have problems to our guests three 3.5 U3 to synchronize the time with the firewall. The ESX hosts are invariably run 4 minutes faster then the firewall. I checked the time synchronization on our NetApp and it works properly in line with the firewall. There is also a simple setting in the NetApp for maximum tilt. I can't find out why or how to fix this problem in hosts.

  Someone at - he seen this before?

  Thank you

  G

  I noticed sometimes you need to (manually) sync successful for ntpd works correctly.  Try this:

  service ntpd stop

  ntpdate < ip.of.ntp.peer >

  service ntpd start

  This ntpdate command can be synchronized manually with your counterpart/Server ntp clock.

• ESX 3.5, iSCSI and Cisco 3750

  I have a pretty basic or newly created three ESX environment 3.5 servers, switches from NetApp for storage and a battery (two) of Cisco 3750.

  IM using for my data vmfs iSCSI store and will only run about 15-20 VM at best. This isn't a great environment but I want to plan for future growth and I won't get a second chance to get the stack of 3750 correct configuration.

  I have 2 GB ethernet by the host to the storage and 4 GB of my NAS ethernet ports all converge on the stack of Cisco.

  Can someone point me to a cisco config guide or the white paper which can guide me for the installation to take advantage of the cross battery etherchannel and balancing of load on the side of esx?

  Suggestions?

  Experiences?

  Advice?

  Much appreciated in advance.

• 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

• Install ESX 4 on iSCSI SAN?

  Hello

  I'm quite new for esx and SAN, so perhaps this question is quite simple to answer... I tried google for several hours, but could not find appropriate answers.

  has got 2 dell r610 (broadcom 5709 with toe and iscsi not unloading, NONE of the local disk/controller) and a md3200i. This configuration was performed by dell, I just told them, wie needs a functional eviroment for 2 servers and storage. then they told me: go with no hard drive and install esx a flashdrive...

  I tried, but discovered after several hours that it is not possible to make a flash only installed, because esx need a partition vmfs for serverconsole data store, which will be created during installation. large

  so I thought: hey, I got 2 TB worth of disk space on the md3200, why not use that for the data store... so I created 2 LUNS dedicated and defined a r610 of each host. in the Storage Manager the md3200 detected the boradcomes as initiators...

  If I shot to the top of the installation... and what is the frag, no SAN to choose...

  connection between NIC and md3200 works (when I select the NIC as a boot device, it connects to the md3200)...

  what Miss me? what I did wrong? or is this not possible and we buy local / controllers of discs? (then I'll have a little chat with the dell technician who recommend that installation)...

  Thanks for your help

  This is what Dell recommends that do you. ESXi loads completely in RAM and done very little written to disk (once per hour, it copies the configuration to an alternate boot partition). All logs are written in a ramdisk so it would be wise to create a location on the San, and then point the logs on this directory

• several host esx on an iSCSI LUN?

  I use openfiler as my iSCSI target, and I just traced all the space available for a logic unit number with the intention to use it for the three ESX hosts.

  Can I share a LUN on multiple ESX hosts?

  (or, I have to create three LUNS... one per ESX host).

  The reason I want to do a logic unit number is so I can bring up a VM on another ESX host without adding storage or move the files of the virtual machine.

  It is supported and even necessary for things like vMotion, etc.. Just make sure you have your SAN configured to allow simultaneous access to the same target.

• 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.

• Initiator iSCSI and virutal switching

  Hi all

  When you set up a smaller ESX laboratory with only 2 cards psyhical best practice is to configure it up like this:

  pNIC0 - & gt; vSwitch0 - & gt; Portgroup0 (service console)

  ..................-&gt; Portgroup1 (VMotion)

  ..................-&gt; Portgroup2 (storage area network)

  pNIC1 - & gt; vSwitch0 - & gt; Portgroup3 (the VM network)

  Then, assign pNIC1 as the backup Teddy to Portgroup0, Portgroup1 and Portgroup2. Finally, assign pNIC0 as the Teddy to Portgroup3 backup. It works better but when them VLAN is enabled. You want to configure explicitly each portgroup strict failover mode and not to use any form of load balancing.

  However if you use a device with an initator software iSCSI, you need to install a 2nd Console of Service if the iSCSI is on another network? and you want it to be on another network?  So that being said would be your configuration would look like the following?

  pNIC0 - & gt; vSwitch0 - & gt; Portgroup0 (service console) 10.10.1.20

  ..................-&gt; Portgroup1 (VMotion)

  pNIC1. - & gt; Portgroup2 (storage area network) 172.16.1.10

  pNIC1 - & gt; Portgroup3 (Service Console iSCSI) 172.16.1.11

  pNIC0 - & gt; vSwitch0 - & gt; Portgroup4 (the VM network) 10.10.1.X

  "However since your 2nd nic is on a differnet IP / network switch option custom" really work so what is the best configuration in a situation like that?

  When you set up a smaller ESX laboratory with only 2 cards psyhical best practice is to configure it up like this:

  pNIC0-> vSwitch0-> Portgroup0 (service console)

  ...-> Portgroup1 (VMotion)

  ...-> Portgroup2 (storage area network)

  pNIC1-> vSwitch0-> Portgroup3 (the VM network)

  It is the recommended configuration.

  However if you use a device with an initator software iSCSI, you need to install a 2nd Console of Service if the iSCSI is on another network?

  No you don't need a 2nd port SC. The supreme court should just participate in the iSCSI network. You can do this by using a route/router or firewall.

  HC participates in the iSCSI network as the original configuration will be fine. A second port SC is not necessary but if you really want to add - we do:

  pNIC0->-> Portgroup0 (service console) VLAN100 vSwitch0

  ...-> Portgroup1 (VMotion) VLAN200

  ...-> Portgroup2 (storage area network) VLAN300

  ...-> Portgroup3 (service console) VLAN300

  pNIC1-> vSwitch0-> Portgroup4 (VM Network) VLAN400

  All portgroup on the same VLAN can talk to all the other exchanges on the same VLAN.

• Problems with the initial web page et al.

  Hello

  I just downloaded Foglight and created a virtual machine from the file .ova.

  Logging on to the server Foglight has worked since the console - I need to manually change the IP address.

  I ping the Foglight Server from a computer on a different subnet.

  Following the instructions I can connect with a web browser.

  This fails as if the server is not active.

  Port 80 seems to be open, but tomcat is running.  Netstat - ano says tomcat has no open ports.

  On a likely related note, when I try to use putty (ssh) to the VM guest, I am challenged for a password, and

  Enter by default of the doc to install, but it does not work with access denied.

  When I use ssh from a Linux box on the subnet, it records the machine, then abandon the connection.  The following connections for this host fail with a "man in the middle" warning.

  Ideas?

  Thank you-

  Rob

  Hi Rob,

  When you have changed the IP address, you use the /usr/local/vkernel/scripts/changeIp.sh script?  If you tried to manually set using other methods, Tomcat configuration files will not be updated, and if the web server will not respond.

  The login/password for SSH usage is vkernel/vkernel.  Some people type it as 'vkernal' but it's 'vkernel.  Does not root via SSH.  You will need to "known" to the root once you have logged in as vkernel.
