• How to clean and do a fresh install with attached iscsi LUN?

  I intend to migrate both esx 4.1 with esxi5.1 hosts before you wipe and do a clean install.  Each host is connected to two iscis without, with 4 LUNS of each SAN attached to each host.  Each lun
  spread over 3 degrees is. I plan on vmotion (not storage vmotion) guests from one host to another to make the upgrade.  I'm stuck on the determination of what will happen to the iSCSI LUNS after I
  upgrade to esxi5.1 guests.  It seems that I should just be able to reattach, but I'm not sure.  Can I just attach the LUNS to the new installation 5.1 hosts and see all the
  VMDK intact, or is there something that I am on?

  And should the migrated to another host virtual machine continues to run on the iscsi san, while I upgrade of the host, they were released since then?  It seems that storage must be removed from the process as the LUNS
  should not remain attached to the host after it is cleared and the iqn name no longer exists.

  
  Am that I on the right track here?  What Miss me?

  jackjack2, understand you this? I went ahead and moved to esxi 5.0 U2 of ESX 3.5 u5. Had to perform clean install and I have an iSCSI SAN. That's what I did:

  1 a taken a screenshot from all my ESX host configurations. Go to configuration-> software adapter-> click on the iSCSI--> properties--> iqn copy map and alias-> click the dynamic discovery tab and note any IP address. You may need these IPs with the discovery of data warehouses later.

  2. after having documented the configs, put the host in maintenance mode.

  3. after maintenance, remove the host from the vcenter server. Connect directly to the host and close.

  4. remove all the network cables. Cable marking help before you detach the cables.

  5. clean install esxi 5.0.

  6. after installation, before rebooting, set the network cables.

  7. configure and test the management network. If your network management test fails, see if you have anything that is entered in the id vlan. Chances are that your port is not shared resources in the physical switch. In this case, remove the id vlan (during the configuration management network) work.

  8 bring the vcenter server host.

  9 configure the network, dns, time, etc.

  10 Add a software iSCSI adapter. This card will have a new iqn. Either you provide this iqn to your SAN administrator so that it can update side SAN, or you can use the old iqn name.

  11. in my case, I made a copy of the new iqn and then deleted. Entered the old iqn name obtained in step 1. Additionally, entered the alias (since one was present before). After that, a new analysis and update still does not fill in data warehouses. So, I went to the properties of the iSCSI adapter and then discovered added tab dynamic addresses IP that did not exist before (otherwise, you will need to enter the virtual IP address of the cluster that you data store (s) belong to). Once the IP addresses have been added to the dynamic discovery tab, he asked if I wanted to rescan the HBAs. I said yes and viola! my data stores have been populated.

  12 Add the host to the cluster.

  Note that you can add iSCSI adapter when you affiliate you the host to the cluster. However, in this case HA will not be happy because no heartbeat of data storages will be detected. In addition, when data warehouses are discovered it may appear initially as not mounted. Don't panic. After a minute or two it will be mounted.

  I hope this helps!

• How to use a larger than 2 TB iSCSI LUN?

  I have a server ESXi (4.1 U1) connected to an iSCSI NAS network, where 4 LUNS have been defined and presented to this host. all LUNS are 3 TB in size. ESXi correctly sees the LUNS and recognizes their size 3 to.

  I know that the maximum size for a VMFS data store is 2 TB, so creating a single data store for each logic unit number would be a waste of space. I know also that the creation of multiple data on a single LUN warehouses is not recommended, and it does not seem work either: If there is already a data store on a LUN, the just vSphere Client won't let me create something else here, it is not even list it in the list of available devices for the creation of data warehouses.

  I know that I can use extensions to create a store of data from more than 2 TB, but it seems to work across multiple LUNS: when I try to increase the size of a data store using the same logic unit number where he resides, ESXi is trying to increase it in fact, it won't go above 2 TB in size.

  My question is: is it possible to combine two extensions in the same logical unit number, so actually creating a composed of 2 extensions 1.5 TB 3 TB data store?

  If this is not possible, is it possible to create two data warehouses in the same iSCSI LUN? I know that this is not recommended, but it should at least be possilbe... but looks like it's not.

  If this is not possible, then... How to make use of these 3 to LUN?

  You can carve up the LUN and then it recombine.

  How to use these LUNS 3 TB is to get rid of them and the re - present as< 2tb="">

• Error creating the store of data on iSCSI LUN (EMC CX4/120)

  I run an error when you try to create a data store on a Clariion CX4/120 system.  Connectivity to the San is performed via iSCSI.  I exhibited with success the target on the storage card and it shows in Configuration > storage adapters > vmhba33 > Details.  It has a capacity of 5.37 to.

  When I go to Configuration > storage and select Add..., I can select the disk/LUN.  The LUN appears here as well.  When I click Next, it fills the device information and location and also reported "the HDD is empty."  After 10 minutes, it generates the following error...

  Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" of object "ha-datastoresystem" on ESXi '172.20.100.78' failed.

  I did some research on Google and looked around here on the website of VMware, and I can't find any references to this error.  Are there log files for the process that I can look into?  I must engage EMC and see if there is a problem with the SAN itself?

  It has a capacity of 5.37 to.

  VMFS data storage limit is 2 TB less than 512 bytes. Try presenting small LUN, then it should work.

• Retrieve iscsi LUNs

  Hello

  I have an iSCSI LUNS presented via OpenFiler to host ESXi 4 (standalone).  For some reason, the host has lost connectivity to the LUN and, of course, the virtual machines that were running.

  I reboot the host which did not help.  I can see the device THAT LUN is presented with success under the section of storage card from the vSphere client.  When I run through the Add Wizard storage, in the storage section, the disk is visible.  However in the next step of the wizard it ends by crashes with an error message "unable to get disk partition information.

  I don't want to just reset the partition table, and re-create the file system I want to retrieve the LUN and virtual computers that it contains.

  Any ideas?

  Thanks in advance,

  Richard

  Did you find anything in the newspapers of the OpenFiler? You have more than three LUNS on the OpenFiler? If so, this logic unit number could be a different LUN then what you think it is? Is there a chance that there is a windows or Linux machine that could have this locked LUN? Or you configured permissions so that those LUNS is available for this single ESXi host? The ESXi host for some reason any seems to think that this LUN does not contain a VMFS partition. The OpenFiler there snapshots of this LUN?

  If the ESXi host can see the LUN, I'd start looking for storage and see if you can find configuration problems there.

• VMotion using on OpenFiler iSCSI LUNS

  Does anyone know if it is possible to 'share' a logic unit number on an OpenFiler iSCSI target so I can use VMotion? So far, I can't my second ESX server to connect to the LUN.

  Should not be a problem,

• 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?

• ESX 3.5 and iSCSI LUNS

  Good so I'm setting up my servers ESX using iSCSI LUNS.  I do not have the LUN in a VM, I want the servers to use.  Is it possible to do?  And how can I do for that implemented?

  Scott

  You must enable initiator initiator or software hardware

  If you go to the inititiator of the software, you must enable on each ESX host, by going to the configuration of the VI Client storage adapter tab. (you will see something like vmhba32, activate it)

  Once it is enabled, you must add your target (as we are talking about software initiator, it supports only dinamic discovery).  Recommendation, isolate the network cards that will connect to the iSCSI network.

  Why my printer say my appears not connected to my computer

  Hello @momodeda!

  Thanks for posting on the HP Forums!

  I don't know why the computer does not show the printer offline, but I would be happy to provide help to try and get communicating them again!

  The first thing I would suggest is to power cycle all the devices.  Remove the power to the printer, shut down the computer and remove the power to the router.  Wait 20 seconds, then reconnect the router.  Wait for the lights on the router to return.

  Plug the printer in and turn on the computer.  Once all devices are back on, try printing again.

  If this does not work then I would recommend uninstalling the HP software.  Once the uninstall is complete, it would be wise to perform a cleanup of the computer disk. A disk cleanup will improve the performance of the computer and remove the temporary files that may cause problems during the installation of the software. Once disk cleanup you must restart the computer and reinstall the HP software.
