• Adding data to the ESX host store

  Hi all

  We are automating the process of adding data to the esx host store. We have all the necessary inputs as a host, Cluster, data center, data store name, store (VMFS) Pat data.

  Do we have the cmdlets to get the result? What is the data store should be added after the configuration of the network?

  We need confirm that the data store must be there in vcenter/Cluster?

  Please help explain the process.

  Thanks and greetings

  If the LUNS on which these data warehouses are defined are zoned and correctly configured as a shared, they become automatically visible on the ESXi node.

  Do you see the LUN on different nodes of ESXi under storage adapters?

• Share data warehouses between clustered hosts

  Hello, we had initially a cluster of ESX consisting of two guests who had shared access to different VMFS LUNS on an iSCSI SAN.

  Recently we bought an additional server, and additional storage and we have some problems to get the extra VMFS LUNs to be recognized by all hosts. The additional LUN is recognized by all hosts after a new analysis to Configuration-> storage adapters, but it seems that data warehouses can be added only for the storage of an individual host and not shared by the cluster?

  Adding the extra VMFS LUNS to a host works very well but they are not immediately recognized by the other guests and whenever you try to add data to them warehouses they insists on formatting the LUN and treating it essentially as a data store different.

  Since there is no problem sharing data between hosts warehouses in the original configuration, I wonder what setting it is necessary to enable sharing between all hosts in a cluster of data store? Thanks in advance!

  Probably, you have LUNS in different ways for each ESX Server (or the new ESX). If any information logical unit number (Lun ID, wwwn, etc.) is not the same for all ESX host tend to view this as a snapshot LUN.

  If you can't find what's going on, you can try a workaround (not too recommended but should work in your environment): go to the ESX configuration tab, click Advanced settings, and look for LVM. DisallowSnapshotLun option under LVM. Change it to 0, click OK and perform a new analysis. Repeat this for all of your guests.

  Please let us know if it works.

• Rename local data warehouses of ESXi host

  Hello

  How to rename local data warehouses of 5.0 ESXi hosts.

  Is it simple; Vsphere Client > right click on the local data store > rename?

  Or host must be in maintenance, or reduced, something like that?

  Thank you

  Mihir

  The ESXi host internally uses the data UUID store rather than its "friendly" name

  Example: / vmfs/volumes/3dfd1a21-63969d0d-8d9b-004328272635 /.

  That is why - as mentioned in the other responses - rename a datstore can be done at any time without affecting the functionality.

• With iscsi failover data warehouses

  Hello to all members,

  Im looking for a solution to create a failover (active/active preference) data warehouses (iscsi) with 2 different devices.

  I read on FT but I think that FT do not create a failover with data warehouses (transparent failover) hosts only, correct?

  I need a solution for reading/writing in the two data stores at the same time.

  Thank you very much and sorry my English.

  Welcome to the community,

  you are correct FT so that DRS and HA only care about the workload of VMS, not storage.

  For the requirement type (transparent failover) you will need a storage based replication/mirroring as HP P4000 (formerly Lefthand).

• displacement of the configurations of lab manager between the ESX server host computers / data warehouses

  Hello

  Is it possible to move configurations of lab manager between the ESX server host computers / data warehouses? I don't see an option in the library & gt; Clone library. Thank you!

• ESX host managed by VirtualCenter servers all see the same SAN LUNS / data warehouses

  Scenario of

  I have two separate deployments of VirtualCenter (in the same physical location) VCA and VCB with each deployment management 5 x ESX hosts (10 in total).

  All 10 hosts are allowed to look at the same SAN LUNS / data warehouses?

  Or I have to isolate five VCA hosts and five guests to their own SAN LUNS VCB / data warehouses?

  Box293 wrote:

  Basically, we have our direct environment and we are on the beta program for VI4.

  I want to turn off a virtual machine in the direct environment and then pull it out of the inventory.

  Then I want to go the VI4 Beta and browse the data store and add this virtual machine to inventory.

  These two environments may see the same LUNS / data warehouses.

  I did and it works however I want to make sure that it is an approved practice.

  You can do that normally without any problems. Even if the virtual machine is in a different datacenter inventory and there Powred-Off. You can map the logic unit number on the VI4 and add to the inventory of the VI4 another host.

  Recently, I did this practice to migrate from host with virtual machines in a different subnet to the host who knows the same setting SAN LUN in the other subnet.

• Internal data warehouses DMZ hosts?

  Hi all

  I hope I'm posting in the right section, and this makes sense.

  We currently manage two groups separated, managed by vcenter.  One for all our internal servers and one for our DMZ servers.  We have our guests DMZ nic 1 and nic 2 combined for the console, vmkernel, and data warehouses.  Two of these network adapters are connected to our internal network.  We then nic 3 dmz1 and nic 4 on dmz2.  Each set of network interface cards is assigned its own vswitch.

  Data warehouses for all customers of vm on the DMZ cluster are NFS targets on our internal network of san. Each guest virtual machine is only affected 1 network card with access to it's special DMZ.

  My question is about safety.  We have been operating this way for awhile, but my networks/security guy is concerned that in some way, the virtual machine can be hacked to access all the cards that are connected to the host, or the virtual machine can be hacked and someone might potentially have access to in-house on our SAN data.

  What are the best practices for this scenario?  Should I currently have security vulnerabilities?  Assuming that this configuration is ok, can I give my guy from network to facilitate his concern for information?

  Our san is a Netapp.

  Edit: misspelling of nic4 for dmz2

  Hi SLCSam

  The way I understand how ESXi handles this (and someone please correct me if I'm wrong)

  Is that ESXi handles all the traffic of independent disk of the virtual machine.

  That's why the only VM knows how to send SCSI comarnds to her hyperviser who then rewrote the comarnds and sends it to the virtual disk files.

  This is why each VM has access to its own virtual disk and nothing else on the data store.

  So if one of the VMS is hacked, data on this virtual machine will be on display, but that's all.

  The virtual machines that are running on these clusters are all independent computing environments. And do not have access to each of the other files.

  Consider as turning several independent servers. It cannot write to other discs except via CIFS or similar.

  From what you wrote, you have nic1 and nic2 as a trunk serving admin. and drive networks

  You have 2 different DMZ then nic3 and nic2

  Nic2 therefore seems to be linked to the network disk in the DMZ.

  It is a major problem. Since then, if one of the virtual machines in the DMZ is compromised, VM said could speak to the SAN via NFS (since they are on the same layer 2 network) and this will expose the hard for other virtual machines (possibly internal) files.

  This assumes that there no VLAN involved. Because if the DMZ and the disc of the net are on different VLANS this problem does not occur.

  If it is typo and the network admin and the drive is on nic0 and nic1 or there is configuration of VLANS to separate the traffic of layer 2, then there is no problem with this Setup, even if a virtual DMZ computer is hacked.

• Host does not see some data warehouses

  I add a new host in a cluster of ESX 4.  ISCSI Storage Adapter on all hosts (old and new) detects all available Lun, 10 in total.  However, 2 of the LUNS appear not in the list of data stores in the new host.  Thus, guests see 10 stores of data.  Guests are running live virtual machines that reside on the 2 "missing" data warehouses.  The new host sees only 8 of the 10 stores of data.

  "in/var/log/vmkernel.  What to do with these averages of message?

  It could be due to various reasons:

  1. lost on the host partition table.  Check with fdisk-lu < devname >

  2 LUNS can be detected as snapshot.  -> esxcfg-volumes - l should show snapshot volumes.

  esxcfg-volumes - M < Datastore UUID >

  This will force up the volume.

  vmkfstools v

  to refresh the storage.

  then if all goes well, you should be good to go.

  3. corruption of LUN. -> Please contact VMware support or support from the SAN vendor to fix it.

• ESX 3.5 can not see data warehouses, (but can HBAs)

  I have a problem with multiple ESX servers that I'm putting it online.

  They use a San, and LUNS are configured correctly and are on the configuration of the storage adapters page.  However they are not in a storage configuration.

  I tried to add data warehouses, but the LUNS are not listed. I also tried a new analysis of the HBA and even reboot the host.  LUNS have not appeared.

  In addition, a couple of live servers in the same farm "fell" ONE of their inventory.  I am very reluctant to perform a new analysis on the living hosts where it falls the rest of the LUN.

  Someone at - he seen this before?

  Iain,

  If you can see them, then your zoning is OK, but if you can't access it, you must check your LUN masking is implemented correctly.]

  Check your zoning and your mask and let us know how you go

• If I put in place an openfiler VM as a data store iSCSI &amp; vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

  The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

  Thank you!

  The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.

• Connect an ESX host 4.0 in a store of data VMFS 3.31 with vMotion, and ESX 3.5 hosts

  Hello

  I moved 2 x a new vCenter 4.0 3.5 ESX hosts.  I also have a new ESX 4.0 host.

  Can I connect this ESX host 4.0 for the data store using the 2 x ESX 3.5 hosts?  It is a VMFS 3.31 on a CX3-20 SAN data store. I was then going to vMotion virtual machines to the new host and reinstall the old.

  I just fear that the new ESX 4.0 host will do something to the data store that make it incompatible with the older ESX 3.5 servers.

  Thanks in advance,

  Euan

  Yes, you can connect and use these data with ESX versions warehouses. If you have sVMotion it will work as well. On ESX 3.5 you can only move the guest as a whole on an ESX 4.0 host, you can move the vDisks independently.

  It is perhaps unnecessary, but when I update the ESX 3.5 servers 4.0 I unplug the storage until the update is running. Just in case...

• Removal of host SDR data warehouses

  Hello

  I have a scenario where I want to migrate to a host and the VM between two clusters. I unfortunately had a number of DTS data warehouses attached to the host, no virtual machine is running from these storages of data on this host... I'm trying to disassemble stores but as expected get the error indicating that data warehouses are part of a cluster of EIM.

  Is it possible to no disturbance delete Host data warehouses.

  Thank you

  Steve

  So, what you want, remove some cluster DTS data warehouses and pass a host of a DRS cluster to another's is?

  Try the following steps:

  (1) remove the DTS cluster data warehouses, just move the data store outside the cluster for DTS;

  (2) move the host to the new DRS cluster target, if you have virtual machines running on it and cannot put the host in maintenance mode, you will need disconnect host, remove from the inventory and then add the host again to the new cluster.

  (3) If you wish, add data warehouses to the DTS of the new DRS cluster cluster.

• 5.5u2 ESXi host will not mount CF data warehouses

  I am the admin in a test lab, so many times I have to "make do" with what I have for the material.  I recently reassigned a R910 Dell with 64 GB memory in a 5.5u2 ESXi host.  It has some storage SAS (2.5 to) and some (CT 11) directly connected FC storage and some FC HBAs for use by VMs to send data to the tape library.

  Recently, we had a power failure, and this host does not reconnect to the CF storage when she returned to the top.  (Duty to "make do" with what I means not having is not the capabilities of UPS).  I can tell the host of HBA see it properly and sees the LUNS on RAID controllers, but refuses to mount.  I go through the add storage Wizard, and he sees that there is a store of data storage VMFS, but always refuses to mount.  I also tried to remove the redirection to the two FC HBA that have been set up for this purpose, but it made no difference.

  I have now three users unable to work because they cannot access their virtual machines on storage of this FC.  I can't even transfer them off to use the SAS storage form.

  I think it might be the cause file system damage, but I'm not sure.  Someone at - it suggestions?

  Have you ever tried to set up data warehouses from the command line (see, for example, http://kb.vmware.com/kb/1011387)?
