• Best way to remove the LUN of ESXi 4.1?

  I know that KB 1015084 talks unpresenting a LUN that contains a store of an ESX/ESXi 4.x host data without deleting the contents of the data store.

  What is the proper procedure to remove LUNS if:

  (a) I moved ALL virtual machines off the LUN to the other storage (DAS, NFS)?

  (b) the SAN will have his replaced controllers (2012i G1 upgrade controllers of P2000 G3 MSA)?

  Thank you, Tom

  If you have empty LUNS that you no longer use, simply remove them from your inventory. Once they have been removed from inventory, have your team of storage not present and remove zoning.  From there rescan your storage adapters to make sure you can't see the LUNS in question

• Problems with masking the LUNS on ESXi 4.1

  Hello

  Im trying to delete a data from a cluster of ESXi 4.1 store but I need to keep the information on here. I read the correct way to proceed is to use LUN masking and delete the data from the end of the storage store.

  When I try to create the rule of the claim using the following command:

  esxcli corestorage claimrule add - rule 192 - location - A vmhba37-C t 0 t 0 L - 1 - P MASK_PATH

  I get the following error:

  Errors: Extra noted arguments of the parameters at the end of the entry: "-'' 192' ' rule - you 'rent' '-has ' 'vmhba37' '-it '0' '-you '0' '-the '1' '-P' 'MASK_PATH'"

  This happens on both hosts that I need to remove the data store of.

  Anyone know how I can add the claimrule with success?

  Thank you

  Try using this: esxcli corestorage claimrule add -rule 192 t - slot - a vmhba37 - C 0 t 0, L - 1 Pei MASK_PATH

• Stream access to the ISCSI LUNs on esxi v4

  Greetings,

  Wonder just anyone could throw me some lights on it?

  Esxi v4 does support stream access to a single lun? The reason behind this is I want to consolidate LUN based on roles (exch, file, etc.), that is to say, a lun (datastore) will host all the servers exch only running on different hosts.

  Thanks in advane.

  Hello

  Yes No... multi host access to iscsi LUNs is possible... that's what san / storage isa he's shared on the subject. Just make sure that Suur iscsi luun u plan on using is in the list compatibilityy supported so that u get the support of vmware in the future if you need. ESX / ESXi have a clustered file system.

  Best practices to eliminate a unit number logic host ESX 4.1, as described in detail in the KB 1015084, are as follows:

  1. Unregister all objects in the database including models and virtual computers
     
  2. Ensure that no tools 3rd party accessing the data store
     
  3. Ensure that no aucune fonctionnalite feature of vSphere, such as storage i/o control, only use the device
     
  4. Hide the ESX host LUN by creating new rules in the PSA (Pluggable Storage Architecture)
     
  5. Anyone physically appropriate LUN of the ESX host using table tools
     
  6. Rescan the SAN

• How to remove safely LUNS of any army of ESXi.

  Dear team,

  I have ha/drs cluster enabled with 4 esxi host. I deleted the 2 ESXi host data store and the same thing is visible in the add storage wizard. I want to cancel the map safely those LUNS of these esxi hosts, before the deletion side SAN I need run commands that we were in esx4.x (rule creation mask)

  need your help to remove these entries from lun to esxi all host them once those LUNS uncharted side san I don't want any kind of errors in the vmkwarning vmkernel\------vmksummary------message log.

  Appreciate your help...

  Mr. VMware

  You can ignore these alarms. They happen to me every time I do it. You have performed the proper procedure. Although I usually remove the LUN manually and do not let the detach operation to do. Also, if you use HA-check is not a heartbeat data store.

  But the alarms are normal, worry not.

• Presentation of vmfs LUNS 3.33 to Esxi 5.0.0,914586

  Dear Experts,

  I have

  1) Esxi 5.0.0 build 914586 on a host

  (2) another host with Esxi 4.0.0 208167 who have a lot of machines

  I want to move a virtual machine from this second host located on LUN with filesystem 3.33, I want to know if it is possible to introduce this system LUNS for Esxi 5.0.0 build 914586 files?

  Waiting for your answers.

  Kind regards

• Expansion of the existing space on LUN

  I wanted to confirm that the following steps are still the best method to expand a LUN formatted with a single VMFS partition space and make sure that I don't have lack of someone who came up with a more elegant solution.

  1. create a new LUN with the space to require it.

  2. move all virtual machine hosted on LUNS with insufficient space for this new logic unit number.

  3 anyone to the ESX host logical unit number and remove it from the storage device.

  Anyone using the following KB:

  Unpresenting a LUN that contains a store of data from ESX 4.x and ESXi 4.x

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1015084

  The increase in the VI client option creates a scope for the partition VMFS and scopes are a tool of the devil.

  With vSphere 4 you can hot - develop the LUN on the storage, and then increase the size of it. This will not generate the extensions. I think that is much more elegant and I can say that it works with Clariion, Symmetrix and Equallogic, EVA (I saw it happen and no problem at all)

• the upgrade to esxi 4.1 and 5.1

  Hello

  I'll be in place upgrade of a host of 4.1 to 5.1 group

  I intend to use using kickstart

  updated - firstdisk = local

  I think the installation is on local disks, but there a lot of LUN fc attached

  question is going to be be sure to use

  updated - firstdisk = local and this installation script?

  should I disconnect all the fc LUNS before installing?

  We do not want to make too many san team

  Thank you

  Since I am the SAN guys too... I always unplug the network storage ESXi when you perform an upgrade because this speed up installation and reduce to the minimum the risk of selecting a wrong option.

• Facing problems of performance with ESXi

  Dear Sir

  I am facing a problem and I couldn't find a solution for her, I have two virtual environment on the site of min and the other on the recovery site, and I use SRM between them.

  The main site contains 12 SUN 6270 blade system 5.1 of VMware ESXi and vcenter 5.1 with clarion Cx4 (SAN storage)

  The DR site contain 5 blade Dell 5.1 of VMware ESXi and vCenter 5.1 with clarion CX4 (SAN storage) system

  I'm Clariion Storage VMAX, my question is on the main site when I add and mount LUN to ESXi hosts when I rescan there took an hour to complete a new analysis, the performance is very bad, in the face of the strange disconnect on the issue of the host, although I checked the compatibility between the Sun and ESXi 5.1 It is compatible

  the DR I'm not confronted with this problem it is fast and the performance is excellent.

  I need a solution please

  Fixed after I removed the clarion and fix some issues on Sun blades fiber cards

• Present LUN storage

  Hello

  Please let me know, what is the process to present the LUN of 256 in single ESXi host, I hired a few parameters to change... Is this true? If true, please share the steps.

  Thanks in advance.

  Hello

  Please note that 256 LUNS by ESXi host is the maximum configuration in vSphere 5.1. This configuration is fully supported by VMware.

  Somehow goes beyond this limit is not recommended and you could not get support if you have problems with this host in the furture.

• How to create LUNS target the same data store?

  In vnx5100, we created two partitions (MON) to be shared separately with 2 VM machines for clustering

  The question here is, that I have assigned the size of the LUN to a new data storage. And when I created ROW for a virtual machine, I had to choose the target LUN, but I wasn't able to see the unit number logic I'm looking for (the one that I have allocated for the storage of data, I created).

  The question here is:

  Why the logic unit number assigned to the storage is not displayed in the list?

  Do we need to create a LUN for the data store and a separate LUN target in Vsphere with the same size of the LUN in VNX?

  What is the target LUN in VMware (vsphere client)?

  Kind regards

  To a RDM and VMFS data store, you must create/submit two LUNS for ESXi hosts. What is stored on the VMFS data store is only the RDM mapping file (this will be created at the time wherever you add the raw LUN to a virtual machine), who shows up with the size of the RDM LUN, but requires no available disk space on the data (as a few bytes) store.

• Anyone ESXi storage

  What is the best credential LUN that I could share with the storage team to get the good ONE of the battery of ESX Servers unpresneted. I have ESX 3.5 running in my farm.

  You can determine this by different target values.  The vmhba2:2:48 translates hba2, target 2, lun 48.  The other is target 3.  Since the other LUNS are different sizes at each target, which should help storage administrator choose the one to delete.

  If you are running 3.5 there is little risk in unpresenting a lun.  Make sure that there is no virtual configs machine (CD with ISO) or backup application or other 3rd party applications access or what causes host to access the lun.  3.5 handles ok, but the PSA architecture with 4.x and above can cause ODA condition.  Check the knowledge base for more details or just google unpresenting a lun in ESX 4.

• How to reach esxi host 5 on storage area network

  I have a Dell PS6000E on my network.  I would like to create a volume on it and use it as a shared storage for a new configuration of esxi5 with 2 hosts.  The PS6000 already contains 2 volumes in use by other servers (physical).  To access the PS6000 via my regular local network hosts.  Is this possible, and is there a documentation on how to put in place?

  Thank you

  Welcome to the community - I guess you access the PS6000E are configured for iSCSI or NAS/NFS, you will be able to access as shared storage long ESXi hosts can reach the unit. Because ESXi hosts will not be able to share the LUNS in use by other servers, you're going to create a new LUN for ESXi hosts. This storage of ESXi - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-storage-guide.pdf - guide that has information on how to configure your ESXi servers to access the storage.
