Round Robin policy with only some HBAs?

• Why you should not use NMP/round robin MPIO with MSCS in ESXi < 5.5?

  There, could someone explain to me why MSCS do not work well with turnstile NMP on ESXi < v5.5?  Best explanation I've seen is that each path is "seen" differently by the guest operating system continuously, send commands to reset and SCSI reservation everything slow.  No doubt this could complicate situations requiring a turnaround as well...

  Looking for a good explanation - which would also help me to understand how it "works" in ESXi 5.5 + now.

  According to Cormac Hogan:

  In the past, political path of round robin might not supported on MSCS shared storage. It was because of the inability to release SCSI reservations on some routes when the reserve has been placed on a different path on the same disk. With the release of vSphere 5.5, this problem has now been addressed and we support RR on storage that is consumed by the MSCS nodes.

• Share with only some members of the homegroup?

  I'm just starting to use networking and Windows 7 homegroups. I have a desktop PC and a laptop, Windows 7 64 bit on my network. Both have 3 user accounts with the same name. My account Steve has the same name and password on both. I want to be able to share files with myself in the residential group and no one else. However when I put my files on the desktop to be shared on the homegroup, it shares with all other accounts on the laptop. I can't share only with Steve on the homegroup.

  It makes no sense at all... How can I do this?

  Hi Steve,.

  Method 1
  When you share the file in the home group, you have an option for specific people. I suggest you to select the specific option and give permissions for people in the home only group. Read the following article.

  File sharing essentials
  http://Windows.Microsoft.com/en-us/Windows7/file-sharing-essentials

  Method 2
  I also suggest you to set the permissions for the share correctly on both computers.

• Make an object query with only some columns?

  I need to make several identical cards using different queries, each using the same columns, e.g. 'name' and 'age '. I thought I could use a makeChart (query) for this function. The trick is, I make sure every request I have pass contains the variables 'name' and 'age '.
  
  Rather than having the app to jump when I don't have the names of right column, I thought I might have makeGraph() accept only a custom request object containing 'name' and 'age' in the form of columns. Then when I run my questions, I can copy the results in this object of the request and which pass to the makeChart() function. Is this possible?

  What about passing as a parameter column names? Then the column names can be dynamic. You can set whatever you want default. Name and age if you wish.

• Change the path to the Round Robin of the newest storage used

  Dear Experts,

  For one of our guests (on two hosts total), which is presented with two data warehouses:

  -Storage 1 (works with RoundRobin vmware)

  -Storage 2 (works with most recent used vmware)

  I need to know if I can change it so that things work and there are two VM in this data store 'storage 2'.

  All the foregoing gave two data warehouses are working with (Round Robin vmware) with host 2nd in our environment

  Please notify

  Just did on one of the used data stores. No problems.

• Can definition of Round Robin way strategy - I just use the GUI?

  I have HP EVA6400 arrays and also HP XP20000.

  I use ESX 4.1 U1 and the recommendation of HP is using Multipathing Round Robin policy.

  I guess I could just use the vSphere client and select configuration > storage > datastore > properties > manage paths > Round Robin > change

  
  This approach would have certainly changed politics of this server for the selected LUN path, then repeat for each.

  But I read something on a blog lastnight that said having to perform the setting of the path of the CLI to set VMW_PSP_RR nmp esxcli.

  
  Can someone enlighten me please.

  
  Thank you

  You can use the command-line like esxcli well:

• Trapezoid with only 2 rounded corners (CS6)

  Hello everyone. I am a beginner in Illustrator and I am familiar with the basic tools and actions, but I couldn't draw a trapezoid (or indeed any shape) with only 2 rounded edges while the other 2 still strong. I work at the CS6.

  I found a workaround to draw a path with a sharp angle, using the effect of round corner, a copy of the mirroring and lining up properly with the original and finally creating a trace (or triangle) to fill in the empty parts. (See pictures attached) but when I unite or join all the corners are rounded or the form becomes disfigured. I can group together and use this way, but I think that there must be an easier way.

  What I want to draw:

  

  How to draw it:

  

  Thanks in advance for anyone who could point me in the right direction.

• Why not want to use Round Robin now (vSphere)?

  Given a configuration of storage fibre channel with more than one of THEM in each server (and more than one switch in the fabric) and what VMWare calls a table "active/passive" (where a single SP both "owns" a logic unit number), I saw messages in the last (see links at the bottom of this message) explaining how over time MRU can cause all of your traffic to fibre channel end on

  a single switch/HBA.

  So I wonder now because it is supported in vSphere, why I would want to use round robin for a table where vSphere uses by default a path MRU policy?  What's the downside for RR?  Is it safe (according to the docs RR is smart enough to only use 'active' paths in an active-passive array, but that is the case)?  Everybody use it now?  Alternatives that involve manually the balancing/re-balancing active links?

  These are positions that made me question initially MRU:

  • http://virtualgeek.typepad.com/virtual_geek/2009/04/understanding-MRU-behavior-in-VMware-ESX-3x.html

  Thanks in advance.

  Hello

  If you have only 2 HBA ports on your host and they are active/passive then alternating really does not benefit anyone. If you have more than 2 ports and more than 1 port zoned on the active storage processor or your San is active/active then alternating would work fine.

• CF, multipath round robin ESXi 4.1 and HP MSA1000

  Hello

  I'm trying to set up a path of multi round robin on the FC san to access the 1 test data store.

  Our FC network is 4 GB. The ESXi server have 2 HBA must provide ~2*4Gb/s path of Round Robin selection.

  But there aren't any.

  By default, the configuration was MRU and one path marked as 'Active i/o' and another 'Active'.

  Change to round robin, reboot, changed the limit of operation I/O 1, nothing has worked. I see in the performance graph, that a path is never used.

  See the screenshots and the results of the following command.

  Any ideas?

  ~ # esxcli nmp roundrobin methods - device naa.60060b0000839530ab5e8a224fc10023

  Hello

  Right, in the creation of 10 X 100 GB LUN then extenting considers them together is certainly NOT a recommended option. Lets take your scenario of 2 virtual machines with 100 GB VMDK, Yes this would spread the work of two controllers, but why bother. Simply create two LUNS to 100 GB with controllers of different managers, and you have reached the same goal end, more removed the complexity and potential problems in the future.

  With extents, the metadata is stored on the first measure, and so when he changes (snapshot, VMDK growth, turn on/off VMs, etc.) then all of the LUNS that make up this data store get "locked". If you have something that does this too in the first measurement, then you will take on the complete data store.

  Other things to think about with extents: If you lose a LUN (one of the scopes), then you lose the entire data store. Damaged metadata will take on the entire data store (all the LUNS that compose). Let's say you must remove a scope, you must destroy the whole extent, etc.. Personally, it is more flexible and easier to manage individual data warehouses, that is if you have the unit number logic that is no longer used (IOs) then you can move the virtual machines assigned to another data store.

  No, I'm not saying that EVA is not able to use two controllers, just that it is not designed to have two controllers maintenance the same LUN (vDisk). Regarding the EVA, you configure the same, i.e. each LUN is assigned to another controller management and so you are balancing the full workload through both of them.

  If you want a unit number logic to use all possible paths (i.e. two controllers) then you need to use Round Robin and configure it to use the non optimized paths. If your unit number logic is mainly written so you can get some benefits from that cache is reflected across both controllers, i.e. any controller made writing as well get it. However, you take a penalty (overhead) for all readings in this configuration as a request for a read on the non management controller is transmitted to the management controller. Since the vm workloads are normally random (ours is 50: 50 read/write) the gains you make on the Scriptures will be lost on read and actually exceed the delivery, i.e. latency increased, controllers overloaded, etc..

  Kind regards.

• move on to the Round Robin

  Hello people,

  I'm a bit confused. I have my now see that they are defined as VMW_SATP_ALUA_CX and storage (EMC CX) defined on the failover mode 4, host rebooted. I think that now, I can go in each data store and change the path of 'Round Robin (VMware)' selection. I do a lot of MSCS and noticed that the Round Robin is not supported with SAM. I found the underside of VMware. He says Round Robin PSP is not supported for the LUNS mapped by RDM, but then there is a "note" that says with NMP, clustering is not supported when the value of the Round Robin. It's my confusion is not the note by repeating exactly what he says just on top of it, or I'm not getting something? Also, I'm running 5.0, are there other changes that I have to do to make this work?

  Strategy selection of the path (PSP)

  Round Robin PSP is not supported for the LUNS mapped by RDM used with shared cluster storage. If you decide to use PSP Round Robin with your storage array, or if the version of vSphere to uses the default values for PSP Round Robin for the table in use, you can change the PSP claiming the RDM LUN above other PSP. For more information, see editing a unit number logic to use another path selection policy (PSP) (1036189).

  Note: with native multipathing (NMP), clustering not is not supported when the strategy of path is set to Round Robin. For more information, see vSphere MSCS Setup Limitations in the configuration for Failover Clustering and Microsoft Cluster Service Guide for ESXi/ESX 4.x or 5.x ESXi.

  Any help would be great. This confuses me

  -MN

  For data warehouses, use RR and ALUA (4 failover mode) mode.

  For members of the MSCS (RDM) cluster, you will need to use fixed.

• Fault of DNS round robin to 2 connection view servers

  Help! We have recently improved view to 4.6 and have now 2 view connection servers (viewconnect2.wheatonma.edu and viewconnect3.wheatonma.edu) set up with DNS round robin. We have customers to enter the name "viewconnect.wheatonma.edu" and there are 2 records to change the name in DNS to what he (to the IP address of viewconnect2, the other to the IP address of viewconnect3). We found only intermittently when a View Client tries to connect they will get the following error

  "View server connection authentication failed. Initialization failed when connecting to the server ""https://viewconnect.wheatonma.edu:443' " "

  Because now we have just removed one of the mentions A name so viewconnect.wheatonma.edu just points to the IP address of viewconnect3.wheatonma.edu and everything seems to work well.

  I have the SSL from GeoTrust certificate issued for viewconnect.wheatonma.edu correctly installed on both servers, so I don't think that is the question.

  In View manager when I check the settings for each server under "Display Configuration"-> "Servers" here is what I got when I edit entry of each server.

  Viewconnect2 settings

  No Tags set

  Secure tunnel HTTP (S)

  External URL: https://viewconnect.wheatonma.edu:443

  PCoIP Secure Gateway

  Am I missing something? Is DNS round robin is not supported for the connection view servers? The firewall is disabled on the connection view servers

  Thank you

  The problem is that your "External URL" settings are wrong.

  These must represent URLS that get directly on the specific login server and cannot be load-balanced or go through a round robin DNS entry.

  Set the external URL:

  Viewconnect2 https://Viewconnect2:443 or https://155.47.24.11:443

  Viewconnect3 https://Viewconnect3:443 or https://155.47.24.12:443

  This way your connection secure tunnel will go to the same server connection as was chosen by repeating alternating DNS or load balancing.

  Your users always enter https://Viewconnect:443 the view of customers.

  There is an example here http://communities.vmware.com/docs/DOC-14974

  Select this option.
