• Add the host to the cluster vmware and SAN equilogic

  Hello...

  I will add 2 new for our cluster vmware vsphere host... I have not done this before, but think that I got the hang of it...

  But one thing that I am uncertain the San connectivity, is it just to create the map of iscsi on the vsphere host software and then add the adapters iqn name to access the San volumes page and rescan for the accessible volumes in the vmware host?

  That's about all.   Reported Tech on how to do so expressly.

  en.community.dell.com/.../TR1075-Configure-iSCSI-Connectivity-with-VMware-vSphere-5.pdf

  TR1091 shows how to configure VMware ESXi for best practices with storage EQL.

  en.Community.Dell.com/.../Download

  In my environment I use CHAP credentials for clusters of ESXi.  In this way a specific set of ESXi nodes use the CHAP username/password to access EQL volumes.  Advantage is when you add a new node, you only need to provide the name of user and password c.  You will not have to change anything on the side of EQL to add/remove a node.

  Kind regards

• Internet deal with VMware and SAN?

  I am designing my first VI3.5 environment in the face of internet and I was wondering if there are problems with sharing a single SAN network between a data center VMware internal and an external datacenter, VMware.

  At this stage of design I'm not concerned with the network, just a storage security.

  Hello

  I am designing my first VI3.5 environment in the face of internet and I was wondering if there are problems with sharing a single SAN network between a data center VMware internal and an external datacenter, VMware.

  Use different LUN for internal vs external

  Do not use the iSCSI initiators in DMZ VMs

  Do not use NPIV in DMZ VMs

  Set your virtual computer security settings.

  At this stage of design I'm not concerned with the network, just a storage security.

  There usually no problem as long as your security policy supports these actions, because everything goes through ESX (with the advice above isolation). Your concern is to make sure that your San is separated from any hostile VM. IE if the CF is to be default. If it's iSCSI then separate your networks/VMs VM iSCSI networks. I would not use VLAN for that, but that's just me.

• VM (invalid) after deleting a snapshot in VMWare ESXi

  All,

  I if I could delete any snapshot at any time to free up space on my drive, especially when I need one instant more.

  Thus, using the Snapshot Manager, I took a snapshot. Since then, my VM is considered invalid. She is still in progress, but I can't do anything with that (summary is empty, shows considered events null, empty and the console is nothing more than a black window).

  Is it possible for me to get this machine? I was about to make a new snapshot... and I really wouldn't want to see my work as missing.

  Thanks for any help,

  See you soon,.

  OD.

  I just got the phone with support, and in our case, it was the cake.  On the VM host console, vmware-cmd-l showed all the VMS in the inventory except the one in question.  In Virtualcenter, we have removed the server greyed out which was "invalid" inventory, then re-added.  Now all is well and everything seems normal.

• ASM and SAN issues HQ

  Hello

  I have a few problems in ASM 4.6 and SAN HQ 3.0.

  SAN AC 3.0:
  I get alerts email saying that network connectivity is not even if there is no network connectivity issues.  The message is below:

  • [ID: 14.2] A connection could not be made.
  • The HQ SAN server issued the group SNMP requests, some or all failed.  This condition is probably due to the congestion of the network or has no network connectivity.  The server will try again in 60 seconds.  Check your network connectivity and that the storage group is online.  If the problem persists, contact your Dell support provider.

  ASM 4.6:
  For some reason when ASM is refreshing the host, it never ends with one of the hosts (in a cluster).  It sticks to the discovery of Cluster connectivity and I don't understand why.  I also get e-mail alerts saying that Smart snapshots failed.

  Can someone please?

  Thank you.

  There SANHQ available from eqlsupport.dell.com/.../download.aspx 3.0.1

  From the release notes:

  Elements fixed in SAN HQ Version 3.0.1

  The following question has been corrected in the version 3.0.1 SAN headquarters maintenance release:

  Previously, after SAN HQ 3.0 upgrade HQ SAN server could not connect to the newsgroups under firmware version 7 or more and SAN HQ has published an alert (HQ SAN event ID: 14.2) indicating that some or all SNMP requests the group failed.

  This condition is resolved.

• Take snapshots of VMware preferred Cisco Infrastructure

  Hello community,

  We have several Cisco first 2.x and 3.x facilities in the area. All are virtual machines on ESX servers. Before the operations of the crtitcal system (as updates, etc.) I used to take a snapshot of VMware. So far, I never had to use a snapshot to revert to the previous state of the system, but I was always sure to have a snapshot, just in case something goes wrong.

  Now a customer recently asked me if the database would not get damaged if I just take a snapshot of the currently running system. I was courious and tried to look this up, but could not find clear instructions for this. The question that bothers me is: what should I stop NCS before taking a shot or not? Does anyone know what Cisco recommends (kind of best practices) for making snaphsot of VMware?

  Best regards

  Benjamin

  Hi Benjamin,

  Please see the release below notes... Snapshots are supported but recommended to take during their stop. I made quite a few installations and upgrades, and always take snapshots while the virtual machine is turned off, is faster and safer on big high transaction VMs.

• a few questions about ESXi and SAN CF with HP P2000 G3

  Hello everyone!

  I am new to ESXi and SAN, then I need help for her.

  I have Encolosure C7000 system with 4 blades BL460c already installed ESXi 5.1U1 (HP custome ISO image). Everything works fine now, but I do not understand something:

  -What is the management network which I use vSphare Client to connect to? It is a private network to manage ESXi servers what difference with VMnetwork used by Virtual Machines? Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

  -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

  -When I install successful ESXi, I don't know how to start working with SAN. What should I configure P2000 before it be plugged into the SAN switch? Or I can plug it then config later? Because I don't see it on the ESXi server. And on the OS I installed on the Guest Virtual Machines, I see nothing new in Device Manager. I thought that this guest operating system will detect the mezzanine card. But I see only mezzanine card that connect to the P2000 by SAN switch in ESXi (see image here http://img203.imageshack.us/img203/684/dsc04088k.jpg ). To my knowledge, I think that ESXi server have to detect the P2000 as hardware device. Can someone teach me step by step install and configure a San on ESXi? Or show me a tutorial because I searched but only iSCSI results.

  My devices:

  01 7.1 HP BLc7000 CTO 3 IN LCD ROHS Encl.

  04 BL460c G8 servers HP FlexFabric 8.5 10 Gb 2 p 554FLB FIO blade adapter

Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

  Yes, it's a separate network used only for traffic management between ESXi hosts and vCenter - it is also the network used to connect to the environment - that's different, then the network used by your virtual machines

  -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

  Yes the license keys can be reused, and if you use vCenter licenses will be managed by vCenter

  -When I install successful ESXi, I don't know how to start working with SAN. What should I configure P2000 before it be plugged into the SAN switch? Or I can plug it then config later?

Or show me a tutorial because I searched but only iSCSI results.

  Yes, you will be able to configure the San later - by default, the virtual machine will not see the SAn, as it is virtualized by your ESXi host - all the VM will see is a virtual SCSi disk - this doc's guide to vmware for storage - http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-511-storage-guide.pdf - you can visit the website of HP they might have documentation on configuring P2000 for vSphere -.

• What is the best practice for a 'regular' Server VMware and VDI environment?

  What is the best practice for a "regular" VMware Server and VDI environment?   A single environment (ESXi and SAN) can accommodate two if it is a whole new configuration?  Or even better to keep separate?

  Enjoying inputs.

  Quick and dirty answer is that "it depends."

  serioulsy, it depends really two things budget and IO.  If you had the money for two without then buy two and don't have to host your server environment and the other for VDI desktop, their IO profiles are completely different.

  If this is not the case, try to keep each type of use for their own dedicated LUN.

• New to VMware and Exchange 2010

  Hello

  I'm new to VMware and have some questions about the installer.  We just bought a HP DL380 G7 server and Exchange 2010.  I want to virtualize this server with a BES.  I'm trying to understand the best way to proceed.  We also have a Dell EqualLogic iSCSI SAN (PS4000).  Wouldn't it be better for me to boot from SAN and have ESxi installed on the SAN?  Or would it be preferable for ESxi installed on the server and have my VM hosted/installed on the SAN?  Thanks for the help.

  Hello owblueiii,

  I almose same infrastructure such as this, when I started the virtualization process was confused in this place, finally, we kept the boot on local, VMs oniSCSI SAN.

  advantages: 1. because if you have any questions you can the Como.

  2 and also a little difficult to troubleshoot if you have the on iscsi san boot partition.

  3. you can register your vms on san iscsi timing if you want the new ESX installation.

  Hope it's useful to your question.

• Sharing files between Windows and SAN VMFS

  Hello

  I just started the implementation of VMware and have no previous experience with it, so it's been fun.

  I have VMware ESX4 and vSphere works 2 host cluster, ha and FC connections to a San.

  Host1

  Host2

  are both connected to a LUN (vmfs) where I p2v of 600 GB has 2 comments for the test servers.

  Everything works fine, but I want to know now, how do I get the ISO files I have on our area (windows), and I want to bring on the 600 GB LUNS in their own directory so I can load then OS new machines to the host.

  (1) how can I do this?

  1.1) can I take vCenter machine we have and which connect to the LUN (Windows Server 2008)?

  1.2) can the vCenter Server running Windows read the VMFS? or is that something should be added to the machine.

• VMWare and Server 2008 R2 64-bit data recovery

  Hello

  Y at - it no problem using the plugin of VMWare and MS Server 2008 R2 (64-bit) data recovery?  Whenever I try to back up a virtual computer with the operating system 2008 R2 on it, she returns with the error:

  Failed to create the snapshot for VMName, error - 1 (unknown)

  The status message in the Panel said recent jobs:

  Cannot create a snapshot suspended because the snapshot creation operation has exceeded the time off I/O forholding in the frozen VM.

  When I use the same application to save a regular 32-bit version of 2008, it works very well.

  Any ideas?

  Thank you

  Windows 2008R2 isn't an entirely guest OS support on vSphere 4 and VMware Data Recovery.  We are aware of the problem and must lean into it by a version update - for now, 64-bit Windows 2008 R2 is not supported.

• HA and SAN traffic on dedicated NIC port

  Hello

  We have a small vmware network 2 HP servers and a SAN. We buy ESS Vsphere with HA.

  If I understand correctly, it is considered preferable for HA and SAN traffic on a port on the network adapter.

  What I need is help with how to implement that.

  We will have 2 spare nic per server ports dedicate to this, one for HA and one for SAN traffic.

  Currently, we use 2 ports per server in swarming mode connected to a subnet and two ports more connected to another subnet, for a total of 4 ports per server. We will buy a 6 port of HP network card very soon, it is most important that they do for our DL 365 HP. This will give us the extra 2 ports per server, to devote to SAN and HA traffic.

  OR should we just use the spare ports 2 Teemed in the SAN and forget to devote to the HA.

  Thank you!!!

  Peter

  HA the traffic runs on the service console / management network. It is advisable to separate, but it is not a must. I will say if you don't have enough NIC to use the grouping of network cards to introduce redundancy, it is more important than anything else, when you run HA.

• Error removing snapshot using vmware-cmd on ESX 3.5

  Hello VMware specialists,.

  whenever I try to delete a snapshot using vmware-cmd ("" / usr/bin/vmware-vim-cmd vmsvc/snapshot.remove vmid ' ") I get the following error:

  {(vmodl.fault.InvalidArgument)

  dynamicType = & lt; unset & gt;

  "

  }

  What is the problem?

  Can someone help me?

  thx a lot

  Rilli

  You have more than one snapshot? in this case, you will need to provide arguments to inform additional cli command which instant you want missing. If you want that all went snapshots just use

  VMware-vim-cmd vmsvc/snapshot.removeall vmid

  Use the following command to get more information on the State of snapshot for VM

  VMware-vim-cmd vmsvc/get.snapshotinfo vmid

  Hello

  I installed an Alfred Workflow (see code below) that will mark all my mails as read. After you run it for a minute, the mail has crashed and I had to forcequit. However, now, when you open the Mail it crashes instantly, even after restart and repair the permissions. I also used the Ctrl + C and CTRL-Z commands in the Terminal to leave the alfred_script, but nothing helped. I'm running out of ideas here, so I hope you could help me either reinstall the mail.app. I could always just switch to a different mail application, but it's kind of a last resort.

  Code:

  Tell application "Mail".

  Define allAccounts on each account name

  Repeat with currAccount in allAccounts

  the unreadMboxes value (each mailbox to the account currAccount the unread number is not 0)

  Repeat with currMbox in unreadMboxes

  (read status of each message to currMbox including the playback State is set to false) true value

  end repeat

  end repeat

  tell the end

  Any input would be greatly appreciated. Can post the report of crash on demand.

  Not sure that Alfred's, but it's just an Applescript script and it would not cause Mail to be planted.

  However, when running through all the messages, it is possible Mail database has been corrupted and it crashes because of this.

  I'll probably get anything out of the accident report, but others might.

  My first instinct would be to rebuild the mailbox. Because you can't do that with him crashing, you can simply delete the databases and it will rebuild them.

  Navigate to this folder:

  ~/Library/Mail/v3/MailData/

  You can either manually through the files, or copy the full path and paste it into go the folder in the menu go to the Finder.

  Remove the envelope Index files. Open Mail and see if it works well.

  If your library does not appear in your folder, hold down the Option key and select library in the menu go to in the Finder.
