• SAN Multi-pathing recommended?

  Hello

  I have a few questions on multiple paths SAN using UCS.

  I will be detailed for each question.

  1. Since there is no option to switch to vHBA, should use the features underlying the o/s (e.g. ESX/ESXi) MPIO? I think that MPIO for ESX/ESXi is enabled by default but to Win2008, we will need to activate it?
  2. My Clariion Bay has 2 SPS (SP - A and SP - B). Each processor has 2 ports. I have these 2 ports cracks to two MDS with a MDS connection to a fabric of interconnection respectively. Should I create two SAN fabrics for these 2 lanes (2 different VSAN)?
  3. What is the convergence time the host to use a different path of failure? (a few seconds or a minute or two?) This is related to question 2, if, for example, the convergence time should take approximately 1 min +, then it makes no difference with 2 different fabrics of SAN compared to 1, because Let's experience downtime anyway.
  4. I have a LUN (0 logic unit number) of start-up and LUN 1 as the store of data LUNS for each host. Since then, my strategy of UCS start-up (for blade/host 1) aura vHBA1 (Primary-> SP-A/port-0, secondary-> SP-B/port-0) and vHBA2 (Primary-> SP-A/port-1, secondary-> SP-B/port-1), should I give to the property for all LUNS for host1 to SP - A?
     • Will I have problems if I put the boot logical unit number (LUN 0) in SP - A and the data store logic (LUN 1) in SP - B unit number? In this case, I don't know how the selection of the path as the path in writing is always on SP - A, and only in the event of failure of the path or the SP failures, it will use the secondary path. Would appreciate some advice on this

  Thank you.

  Hi,
  I have a few questions on SAN Multi-pathing using UCS.
  I will itemized each questions.
  Since there's no failover option for vHBA, we would need to use the underlying MPIO features of the O/S (e.g. ESX/ESXi)? I believe MPIO for ESX/ESXi is enabled by default but for Win2008, we'll need to enable it?
  [Robert] - Correct.  There's a native multipathing pluging (NMP) in VMware, but for Windows you'll need additional config/software.
  2. My Clariion array has 2 Storage Processors (SP-A and SP-B). Each SP has 2 ports. I have these 2 ports meshed to two MDS with one MDS connecting to one Fabric Interconnect respectively. Should I be creating two SAN fabrics for these 2 paths (2 different VSANs)?
  
  [Robert] - Yes.  Connect one VSAN on each FI.  Your FC uplinks will each connect to an upstream MDS (assuming each MDS is not connected to each FI).  You will still have 4 storage paths available to each host using two vHBAs.  3.  What is the convergence time for the host to use another path when failure occurs? (few seconds or a minute or so?) This is related to  question 2 if for example, the convergence time were to take around 1 min+, then it makes no differences having 2 different SAN fabrics as compared to 1 because we'll be experiencing downtime anyway.
  
  [Robert] - Failover for FC traffic is handled by the host, not UCS.  It's up to the host OS to decide how & when to redirect traffic to the alternate path. Normally FC failover is pretty seamless.  FC traffic can't tolerate any lengthy of delays.  As soon as the SCSI command times out, it will jump to the other path. Again, this will vary from OS to OS, but generally its seamless to the application/OS.
  4. I'd like have one boot LUN (LUN 0) and LUN 1 as the datastore LUN for each host. Since, my boot policy in UCS (for blade/host 1) will have vHBA1 (Primary -> SP-A/port-0, Secondary -> SP-B/port-0) and vHBA2 (Primary -> SP-A/port-1, Secondary -> SP-B/port-1), should I give the ownership for all the LUNs for host1 to SP-A?
  
  [Robert]  Yes.  Your primary boot target must be the "owner" of the LUN (and should be the "default" owner for that matter).  Only when SPA fails, will the LUN tresspass to SP-B and the secondary boot path will succeed during server boot up.   Keep in mind, this is only for booting.  Once its up & running, the OS handles failover activities.  5. Will I have problems if I only put the boot LUN (LUN 0) in SP-A and the datastore LUN (LUN 1) in SP-B? For this case, I'm not sure how the path selection will work as the writeable path is always on SP-A and only if path failure occurs or SP failures, it will only use the secondary path. Would appreciate some advice on this
  [Robert] Boot policy & data path selection are two different things.  If your boot LUN is targeting SPA, it will likely maintain that path as the OS loads.  Once the OS loads you can manipulate the path for any LUN. If desired you could set the "Active" path of your Datastore LUN within vCenter to be the other SP (SPB in your case) by modifying the path selection policy and setting it to "Fixed" PSP.  The default Path Selection Policy is MRU (Most recently Used).  This is normally adequate, but if you want to manually load balance your traffic the Fixed PSP policy is the way to go.

• Change of MSCS RDM disk offline after VMware Server or patching firmware finishing or multi path IOPS / s - SQL MSCS RDM disk

  Hello

  Yesterday, we installed a fifth ESXi host at our development center and along that we also had a window of maintenance for other hosts.

  We made:

  • HP Proliant HP Service Pack upgrade to 2014.06.0_784915_001. We have HP BL460c Gen8 servers. The old PSP performed from September 2013
  • Installed patches for ESXi 5.1 U1, the latest 10-15 patches since February. Do not install 5.1 U2.
  • Upgrade VMware Tools on virtual machines.
  • Changed multi path IOPS / s for HP 3PAR from 100 to 1. (esxcli storage nmp ATAS add s "VMW_SATP_ALUA' Pei"VMW_PSP_RR"- IOPS O / s = 1 - c"tpgs_on"v '3PARdata' - M 'VV' EI 'HP 3PAR Custom iSCSI/FC/FCoE ALUA rule')

  After this interview little MSCS SQL cluster stopped working. It does not start because it cannot access the drive. I can see the drive in disk management, but they are all in an offline mode. Can't do anything about them, except a single disc. This one is online!

  Did anyone here have no idea what on Earth is wrong? If I does not tomorrow I have to list a species of Microsoft or VMware. I have not tried to remove/add the RDM-disc.

  Windows 2008 x 64 Enterprise

  SQL 2008 R2

  ESXi 5.1 U1 (latest patches)

  Thank you!

  Finally solved with assistance from HP support.

  Solved this KB KB VMware: change a LUN to use a policy different selection of the path (PSP)

  The "funny", it is that the cluster has been around for 4-5 years and works on EVA SAN and now 3PAR with RR as a policy path, and all of a sudden it stopped working. Perhaps a host profile political trigged in, I don't know. And I could also see and access 5/6 disks, why not 6? And was on the way from RR.

  I asked HP about this.

  Thank you for all your help.

  "I am using a script in actions to clear all roads, since the web found the 'activeDocument.pathItems.removeAll (); " and it works fine when it is called in the menu script not these dialogs at all but when I try to use it in shares, it still appears a dialog box asking for confirmation if I really want to remove" path regardless.

  Try

  or

  app.displayDialogs = DisplayModes.NO;

  In both cases, you probably want to reset to its original state when you are finished.

• iSCSI/NIC bonding/Multi Pathing

  My entire ESX environment consists of all Dell PE2950s, each with 2 x 1 GB NIC in them.

  both my iSCSI servers have 2 x 1 GB ethernet which are NIC glued to maximize throughput.

  For most areas of development, so these are his especially iSCSI and vm vm traffic traffic (like IIS, SQL, etc.)

  What is the best way to config the vNetwork in ESX so that I can use two NICs for ISCSI, but not to lose the LAN feature?  Can I spend 1 iSCSI NETWORK card and the other card NETWORK ISCSI/LAN?

  I posted about this before and I was told that the collage of NIC is not supported for iSCSI in ESX.  I don't know anything about multiple paths...

  I fixed that in the script in my first post. Now he has to work and only to retrieve information about the two groups.

• Political multi-channel Fixed and enter preffered paths balance for a set of RDM Lun

  Hi all

  I was hoping that someone with some experience PowerCLI might help me with the following problem.

  Short version:

  I need to adapt this script http://vmjunkie.wordpress.com/2009/01/29/balancing-lun-paths-on-your-esx-hosts-with-powershell/ to accept the entry of a canonical name text file...

  Long version:

  We have a number of LUNS of RDM used by Microsoft the Failover Clusters, in accordance with the recommendation from the storage provider (Dell), we need to define all teas LUN to have a multi-path of FIXED policy and want to balance these on both paths.

  I can get the canonical name for each LUN RDM using this script;

  Get-VM-Location"Cluster Name" | Get-HardDisk -DiskType "RawPhysical","RawVirtual"| SelectParent,Name,DiskType,ScsiCanonicalName

  (Of http://www.definit.co.uk/2013/03/powercli-script-to-set-rdm-luns-to-perennially-reserved-fixes-slow-boot-of-esxi-5-1-with-mscs-rdms/#more-1526( )

  I then manually identify the LUNS that have to be changed since the text output.  So, basically, I have a text file containing the canonical each of the RDM LUN name I need to change to fixed.

• Impossible to create RDM on sharing NFS - unimplemented function

  Hi all

  I have a problem, creating a map of CRUDE device on a NFS share. Get an error "failed to create ramdisk: function not implemented (2490377)' when you use vmkfstools:

  / usr/sbin/vmkfstools z - /vmfs/devices/disks/naa.60a9800050336d755a5a5a3473355659 /vmfs/volumes/VMDATANFS/eea-cl1-rdm/eeacl1-sbd1.vmdk - a free

  Tried several suggestion in forums, such as from the creation of inside the right way, but it just doesn't work.

  The environment is a vShere 4.1 new installation that has storage NFS was assigned a 2040 of NetApp FAS. For a virtualized Linux cluster we want or need to create a bundel of RDM disks. When I add a disk in the CR of the host (or the customer vSpere directly connected to the ESX host) and select Raw Device Mappings, and then select the LUN exposed, then I need to specify the data store but only can select 'local' and not the NFS share my VM runs on. The store just does not appear here in the list, or I can select 'Save with Virtual Machine' it (the virtual machine is sitting on the store NFS of course).

  To test, I created the NFS name lowercase. does not work

  Also created a VMFS on the NetApp volume and attached to the host iSCSI hollow. This volume appears in the list to store ROW on the use of VC to add a RDM disk for a virtual machine, also I can use the vmkfstools command line successfully this way.

  I think a RDM link must be supported on an NFS share, right?

  Thanks in advance!

  Welcome to the forums!

  You need a number of logic unit or soemthing which are accessible through SCSI (such as iSCSI). NFS is not supported for this feature.

• How to identify the lun has a fixed path, SRM or rr on esx4 policy?

  After reclassification of esx 3.5 to esx 4.0 and Netapp Storage ALUA political path should change from fixed to Round Robin.

  Release	Mode	Recommended Political path	Firmware	Device (s)	Configuration
  ESX 4.0	VMW_SATP_ALUA	VMW_PSP_MRU	Data ONTAP 7.3	N/A	Switched FC

  For alua esx4i can be configured on vsphere cli

  Command for esx and Esxi 4 4 by vsphere cli

  esxcli - Server esxhost ATAS setdefaultpsp psp - VMW_PSP_RR - ATAS VMW_SATP_ALUA nmp

  Command for esx (service console)

  esxcli - Server esxhost ATAS setdefaultpsp psp - VMW_PSP_RR - ATAS VMW_SATP_ALUA nmp

  After setting this LUN ALUA config only new created have the parameter ALUA and alternating by default.

  For the existing LUN political path was with esx 3.5, the fixed value. After upgrading to esx 4.0, they will be set to fixed.

  What is the command to find out what old LUNS are set on a fixed policy and the new LUN is set to Round Robin.

  This vmware blog, there is an example to all. Y at - it a get to find fixed command, rr or mru?

  http://blogs.VMware.com/vipowershell/2008/07/managing-Storag.html

  After a few PMs that I must conclude that the script, which emulates the esxcfg-mpath command, does not support the NAA address that is used by NetApp.

  As a quick fix, you can use the other script I gave above that uses cmdlets Get-ScsiLun and Get-ScsiLunPath .

  Who should at least show you what multi-path strategy is used.

  ypts [9] = 0;
      
  position [0] = 0;

  by offset [2] = 5;

  If you see the commented drawPathOutline draws the i.e two channels, 0 to 3 & 5 to 8 are drawn correctly. However, when it comes to drawFilledPath(), it throws exception saying invalid arguments. I tried different ways to define the offset, but of no use. It works fine when I used the null value for offset, but what attracts as a single path which is not what I want.

  Some how the Blackberry SDK document gives the impressino which he must start and end offset for each path in the case of multi path scenario. However, we need only three shifts for two channels

  That is to say

  shift at the beginning of the first path

  lag at the end & beginning of second road

  offset to end second path

  In the above example we don't need (0,0) coordinate between the paths, so points can be

  int [] xpts = new int [8];
  int [] ypts = new int [8];
  Ptypes = new ubyte [] byte [8];
  int offset [] = new int [3];

  Path 1
  xpts [0] = 50;
  ypts [0] = 100;
  xpts [1] = 150;
  ypts [1] = 100;
  xpts [2] = 150;
  ypts [2] = 200;
  xpts [3] = 50;
  ypts [3] = 200;

  Path 2

  xpts [4] = 70;
  ypts [4] = 130;
  xpts [5] = 120;
  ypts [5] = 130;
  xpts [6] = 120;
  ypts [6] = 170;
  xpts [7] = 70;
  ypts [7] = 170;

  offsets
  position [0] = 0;
  Offset [1] = 4;
  by offset [2] = 8;

  gt.setColor (net.rim.device.api.ui.Color.BLACK);
              
  gt.drawPathOutline (xpts ypts, null, offset, true);
  gt.drawFilledPath (xpts, ypts, null, offset);

  This time drawPathOutline & drawFilledPath works very well.

• The path selected with the pencil tool editing... CS5 vs CC

  I know this is an old issue and I've complained about this over and over. In CS5 I can select several paths and then, using the pencil tool, freely change paths without losing the multi-path selection. It is a great way to tweak a form of paint. CC (2014), it is no longer possible (at least on Mac). Technical support Adobe told me once he was a Bug "Mac admits. Can someone tell me if this feature was "set in CC 2015? Unfortunately, Adobe doesn't bother to fix bugs in the 'old' version They drive just a new version.

  This small function is of the main reasons that I refuse to CS5 to let die on my computer. If this is fixed, I would consider 'redeveloped' to 2015 CC.

  Here is an old video explaining the problem:

  Not been resolved in CC2015 (although I can't see the video, I have to sign).

  As soon as you change a selected path, others get deselected.

• Multi-NIC vMotion with ESXi/vCenter 4.1

  We take running ESXi and vCenter 4.1 and after the secure Channel secure Channel 5.5 class and sitting for my exam in a few weeks, I have actively tried to improve our environment. Previously, to the study and trying to learn more about VMware, we were in pretty bad condition. Relevant material (AMD, Intel CPU, generations of Intel CPU, amount of RAM and CPU), versions hyperviosr Mismatched ESXi and ESX and no redundancy, vmotion and TONS of snapshots as backups.

  In the two weeks since my course, I have eliminated all snapshots (performance daily vCheck to check on the health of the venvironment), emigrated to 5 similar hosts (and memory/cpu configurations) that we had to drag do not, connected to all ports card NETWORK 6 to 2 x 3560g cisco switches and connected the second switch updated ESX to ESXi 4.1 and patched all hosts with Update Manager (nobody used), created the host profiles and compliance on the cluster and hosts, activated DRS and HA, set up a couple of VAPP for STM systems... the list is long

  I still have a lot to learn, but now I'm a bit confused about one thing...

  We use Fibre Channel SAN, one side get our second Fibre Channel switch hooked up for redundancy and I guess that Multi - pathing (?) I have a couple questions question...

  1. set up the second fiber switch would give me several warehouses of data, correct paths?

  2 can I create and separate vMotion in our configuration, using the CF WITHOUT? Any flow of traffic (for vmotion) through the vswitches or he remains behind the FC switch?

  -I know with iSCSI, you want to create a vSwitche separated and installation multi-nic vmotion

  3. in the configuration of the redundant management interfaces do I need to create two vSwitches with vmkernel with separate IP addresses management ports or just create on vSwitch with a vmkernel port and two network cards is assigned to the (two different connected to 2 physical switches physical cards)?

  -We will most likely use VST if we can get the trunk ports to pass traffic defaullt VLAN, so I think it is still acceptable to create separate vSwitches for management, vMotion (if necessary because of the CF) and port VM group? The designs I see online usually use only a vSwitch for VST and multiple is.

  That's all I can think of for now... Just some things that need to be clarified on... I guess I still need a vSwitch vMotion (allocate 2 of 6 network adapters in it) because some type of traffic would pass over him, but I think that most of the vMotion and all the SvMotion would remain behind the FC switch.

  Thanks for any help!

  With regard to the topic of discussion: Multi-NIC vMotion introduced with vSphere 5.x and is not available in earlier versions.

  1.) Multipathing is not related the number of FC switches, but only for the number of initiator and target. However, using several CF toggle availability increases due to redundancy.

  2.) you must differentiate here. vMotion is a live VM migration process to other hosts, i.e. only the workload of the migration. vMotion only uses the network. Storage vMotion on the other side generally used storage connections - i.e. the CF in your case - to migrate files/folders to the virtual machine.

  3.) redundancy for management traffic can be reached in several ways. The easiest is to simply assign multiple uplinks (vmnic) to vSwitch network management. So, a simple 'Netowrk management' will do, and redundancy is made based on recovery of the vSwitch.

  From a design point of view you can use multiple vSwitches for different traffic types, or combine them on a vSwitch by configuring the failover policies for groups (Active/Standby/Unused) port for example.
