esxcfg-mpath-l - driven script

Hi all...

I recently had a problem with some of my ESX hosts, where some HBA ports on the host saw not all paths of our SAN that I expect.

I want to do is to have a script that could collect similar results to the command of esxcfg-mpath-l for each host in a particular cluster, and then export to csv format so that I can have a weekly check to ensure that there no any SAN issues associated with this particular problem...

I have really no idea where to start, or if a similar output is available using commands in the vi toolkit. I had done some reading on the use of plink to do similar things, but id prefer not to go down this road if I have to.

Anyone have any ideas?

My bad. The previous script are several servers ESX because at the time where I was hooked only to one and I don't have a lot of sleep the previous night. Here is a version that accepts VMhost to the pipeline information. However, to do a filtering for discs inapplicable.

filter Get-VMHostMpath {
     $hostview = $_ | Get-View
     $VMHostName = $_.Name
     $mPathLun = $hostview.Config.StorageDevice.MultipathInfo.Lun
     foreach ( $lun in $mPathLun ) {
          $lunName = $lun.Id
          $pathCount = $lun.Path.Length
          $mPathPolicy = $lun.Policy.Policy
          Write-Host -foregroundcolor Yellow "Host server: $VMHostName"
          Write-Host "Disk $lunName has $pathCount paths and policy of $mPathPolicy."
     }
}

Use:

PS >. .\filename.ps1 # you need to point source to make the service in the current scope

PS > Get-VMHost | Get-VMHostMpath

esxcfg-mpath command problem

Hi guys,.
I have a problem with the command 'esxcfg-mpath-l ' -.
as you probably know, in previous versions of esx the release order was clear and understandeable, like the attached photo.
in esx4 the same command generates a ridiculous amount of text which is not understandeable at all...
do you know if there is another command or another way to get the information I'm looking for?
Thanks in advance...

esxcfg-mpath has been redesigned to cope with the reality of the new PSA infrastructure. The old format contains information that are no long guaranteed to be available on a LUN (policies, device COS etc.), he used old style vmhba appoint and confined to Fibre Channel and iSCSI, when you want to identify the paths.

specifically, esxcfg-mpath - b has been added to match the old behavior of-l esxcfg-mpath as closely as possible with the new infrastructure. You can use this with a d flag to limit the output of esxcfg-mpath - b to a single LUN.

You said specifically that esxcfg-mpath cannot see political. This is because not each LUN will have a policy in 4.0. If a user uses a third-party MPP, as the path of the power, then the policy does not exist. This information has been moved to the list of devices nmp esxcli command when guarantees are made on the ownership of a LUN.

Any specific comment, you have everything that is missing from existing orders, I'll be happy to hear.

How to emulate esxcfg-vmhbadevs - m with the Perl API?

I have an iSCSI target that has been formatted and divided into a volume. I want to be able to map to the UUID volume iSCSI target LUN.
esxcfig-vmhbadev - m do it directly, for example in the LUN low, 207 maps line the UUID 4ac128de-d4b8f7c3-a4a5-001ec9ab7607.
vmhba0:1:0:1/dev/sdb1 47a3995d-bf8312ea-aa8a-0019b9f36fbf
vmhba0:0:0:3/dev/sda3 479f6ab3 - 636688 b 2-277 - 0019b9f36fc1
vmhba1:4:200:1/dev/sdc1 4ac127e9-81fb1fcf-1138-001ec9ab7607
vmhba1:15:207:1/dev/sdd1 4ac128de-d4b8f7c3-a4a5-001ec9ab7607
How can I do this using the Perl API? I can get both halves of the information, but I do not see how to associate.
This snippet gives me information on the LUN and the SCSI UUID
Print "canonical name, UUID\n;
My $scsiLUN = $storageSystem - & gt; storageDeviceInfo - & gt; scsiLun;
{foreach (@$scsiLUN)}
Print "". " $_ - & gt; canonicalName
. ", " . $_ - & gt; UUID
. "\n";
}
Canonical name, UUID
vmhba1:15:207, 0100cf000020202020564952545541
vmhba0:1:0, 020000000050014ee0004544c3574443205744

vmhba1:4:200, 0100 c 8000020202020564952545541
Then this excerpt gives me information on the volume:
My $mountInfo = $storageSystem - & gt; fileSystemVolumeInfo - & gt; mountInfo;
print 'Volume Name, Path, Type, Capacity\n';
{foreach (@$mountInfo)}
Print "". " $_ - & gt; volume - & gt; name
. ", " . $_ - & gt; mountInfo - & gt; path
. ", " . $_ - & gt; volume - & gt; type

. "\n";
}

From vSphere 4.0, esxcfg-vmhbadevs has been replaced by a new order with a lot more information called esxcfg-scsidevs. This script is available on the classic ESX 4.0 w/Service Console of course but also in the context of the new vCLI which uses the new vSphere SDK for Perl 4.0 which can take a look at how this new information is extracted.

The command works on ESX 4.0 and 3.5 and here is the output of ESX 3.5 system example:
```

You have listed the vmhbaC:T:L:P mapped to the VML path and then store data UUID, then the readable name for the data store human. You can certainly create a copy of the script and only what you want exactly and that nobody is re - invent the wheel.

Hot Add Remove lun fails in rescan periodical at the time of the withdrawal, although the path is marked as DEAD as planned

So we run the hot add and remove cases from LUNs in the certification for ESX 5.5 with Workbench 3.0 kit

The hot add succeeds to the two manual add and periodic scan... Deletion succeeds manual extraction, but a failure in periodicals rescan same removal so it lists the path out of SERVICE.

Here are the logs

[August 26, 2014 20:24:27: HOTADDREMO] [0] ERROR: LUN is found not deleted after periodic rescan on the first server

So I checked the Vmware perl code that performs this case... it is available at /opt/vmware/VTAF/storage50-cert/VTAF/Test/Storage/StorageCert/FVT/HotAddRemoveLUNs.pm

Sub RunHotRemoveTest

{

.....

# Remove LUN only cause death I/O path. It does not delete the LUN.

# Evaluate for the dead I/O path.

$deadPathFound = "NO";

LogInfo (channel = > $channel, MSG = > "Check the path to remove LUN on $server");

foreach my {$lun (@lunListBeforePeriodicallyRescan)

#my $lunObj = $host2HbaObj-> CreateScsiLun (name = > $lun);

$cmd = "esxcfg-mpath - bd $lun";

My $cmdObj = new VTAF::Framework:Core:Common:Command)

Home = > $host2Obj-> GetName();

Cmd = > $cmd);

my $rc = $cmdObj-> GetReturnCode();

my $cmdResult = $cmdObj-> GetStdout();

my $cmdError = $cmdObj-> GetStderr();

If ($cmdError) {}

$deadPathFound = "YES";

LogInfo (channel = > $channel, MSG = > "mpath command returned: $cmdError");

LogInfo (channel = > $channel, MSG = > "$lun is deleted after periodic rescan");

}

If ($deadPathFound not 'YES') {}

LogError (channel = > $channel, MSG = > "LUN is not deleted after periodic rescan on the $server");

return FAILURE;

} else {}

LogInfo (channel = > $channel, MSG = > ' delete hot with periodically rescan PASSED on the $server ");

}

So if you see the code above, Vmware itself expected the path to show the death, but they perceive three error codes for the output of esxcfg-mpath - bd < lunname >

I think they expect an error to return to $cmdError... But looks at though it lists the path as DEAD, she returns to success... So the $deadPathFound is always set to no. He goes into the path of "not YES" and not the test case...

I would like to open a folder from supported with VMware, but before that I would like to know if someone has faced this problem and had this problem of VMware using any patch in their Workbench... Or if any new workbench has this problem fixed...

We are using Vmware Test Manager: 3.0.0 - 1610638

5.5 storage certification: 3.0.0 - 1337995

VMware Workbench say 3.0.1

Than I went back to our older certification with ESX 5.1 where this matter has passed... and was able to check the logs. It has been performed with Workbench 2.0. In this they executed a more order "peripheral storage esxcli list d lunname" and lists the path as dead and also properly detects the dead path and scored the try with the...

So basically had the question warm Add Remove Lun. It is a problem in the ESX version we use and scripts of WorkBench. If we use the build ESX GA this would have worked. ESX changed the behavior of the command in version 5.5 of GA to a new approach and then back to the old approach again in 5.5 Update1.

The version we use are two versions higher than the release of GA... Therefore, the behavior of this command is different between these two versions.

How to identify the LUN WWN of ESX 3.5

Hi all
We have Vcenter 2.5 environment with 3 groups each cluster with 4 ESX 3.5 hosts. LUN is assigned to each group of EMC clariion and VNX storage boxes. I want to know how can I identify the LUN WWN of ESX console numbers. I tried esxcfg-vmhbadevs - m and esxcfg-mpath - l, but I'm not able to identify the LUN WWN here numbers are these commands HBA cards. I have numbers of WWN of the two clariion LUN and provided VNX nby our storage from these WWN team I want to identify what data store is using storage?
any suggestions

You can try running the command console and after the release?

Run the following command

esxcfg-mpath-lv | grep ^ disc | grep - v vmhba0 | AWK '{print $2} '.

then choose a vmhba unit... IE: vmhba1:02:03...

Run the following command (replace $entry by the vmhba you chose)

esxcfg-mpath-lv | grep disc | grep - v vmhba0 | AWK '{print $3, $5, $2} "| cut - b15 | Cup c - 1-32, 45 | Sort + 3 | grep w $entry | AWK '{print $1} '.

Let me know if you still get the error...

Otherwise, it is also a way to get what you need to use powerCLI... I have scripts on my other computer, but it is currently not available...

To run commands ESX using PowerCLI

Hello

Please can someone help to get a script to run by Powercli ESX commands and capture the output of the Excel sheet. For example, I want to run esxcfg-mpath - l on all servers in the vCenter, and get the result in the worksheet Excel in a neat way.

There are more that 100 ESX host, also is painful run these commands on each of them one by one.

Thank you.

Nick

In the case of esxcfg-mpath command is not so difficult to produce objects of the output.

Something like this should do the trick

Add-vCLIfunction
$env:VI_USERNAME="root" $env:VI_PASSWORD="password"

 $result = foreach($esx in Get-VMHost){
  esxcfg-mpath -l --server $esx.Name | %{
        if($_.Length -gt 0){
            if($_.Contains(': ')){
                $temp = $_.Split(':')
                Add-Member -InputObject $obj -Name $temp[0].Trim() -Value $temp[1].Trim() -MemberType NoteProperty
            }
            else{
                $obj = New-Object PSObject -Property @{
                    VMHost = $esx.Name
                    Name = $_                }
            }
        }
        else{
            $obj        }
    }
    $obj}

$result | Export-Csv "C:\mpath.csv" -NoTypeInformation -UseCulture

Note that this works that for the esxcfg-mpath-l command, other commands produce different output.

And should be analyzed first of all the output.

Change screen nom_peripherique

Hello world
my request for help to the management of the LUN names on my data center.
Currently on my ESX LUNs are attached over 100 and I wish I could change the entry with the display name LUNS created on the storage device name.
When I run the command ' esxcfg-mpath-l ' I this view;
The Runtime name: vmhba0:C0:T0:L0
Feature: naa.6006016055351f00506decc0459cde11
Full device name: disk of DGC Fibre Channel (naa.6006016055351f00506decc0459cde11)
etc.
etc.
etc.
With vCenter Client I rename the device "Display Name" on Configuration - & gt; Storage adapters - & gt; and after launch ' esxcfg-mpath-l ' ;
The Runtime name: vmhba0:C0:T0:L0
Feature: naa.6006016055351f00506decc0459cde11
Full device name: LUN20_100GB_VM_W2003
etc.
etc.
But is possible to the effect of command line?
Thank you

The method should be called from the host storage system, take a look at the API method to see which parameter it requires. I don't have the time to create an example of script, but after VMworld, I should have some free cycles if all goes well.

In the Service Console the path value preferred on vSphere?

Hello
We have a problem here.
Environmental: political vSphere Host, 8 HBAs, path: fixed path of vmware, on 1,000 paths to storage
To reduce the total number of paths we want to reconfigure our warehouses of data and reduce the number of used HBA for warehouses of test and reference using only 2 of the 8 host bus adapters. We use all the time, then put 6 of them on all our servers of vsphere for people with reduced mobility, only two remain active.
That is why we have active and people with disabilities with the help of a script on paths of console service - it works very well.
But after that we reduce active host bus adapters, vsphere seems to forget reset the preferred path (just checked in the GUI). We put vmhba1 and vmhba7 to be active, 0-8 (except no. 6 as is the lsi controller) should be disabled, but on most of these disabled HBA Lun remains the favorite.
On esx 3.5 service console, we were used to:
/ usr/sbin/esxcfg-mpath - favorite - political fixed = - lun = $lun - path = $: ${lun # *------:}}
but these options (favorite, political) seem to be outdated since vsphere, which apparently obtained these commands on the api storage?
Can someone answer the following questions on this issue:
1 did affect the feature if you prefer the path is one of the disabled?
2 will be the vsphere host keeps this configuration after reboot (disabled HBA to a lun, active paths)?
3. is there a new command to set the access path AND / OR politics (MRU, FIXED, RR) to a logical unit number?
Thanks in advance,
Kind regards
Alex

Hello

for active/passive, please use MRU;

as you know, when fixed in use and the LUNS mapped to multiple hosts, 1 host perhaps selects path fixed-to-controller 0 and 2nd host perhaps selects fixed path to controller 1, then the current path will change between two controllers, way stolen here;

Confusion of multipathing IBM SVC

We run ESX 3.5 update 4 so I know not fixed policy is now supported, but the real question is that should we use? Also, do we have the installation path manually or is this native multipath for IBM SVC? In the past, I've used Netapp and installed on the ESX console tools and managed through that, but I do not think that IBM SVC has something like that. Also our CVS is version 4.2.1.6

It is not any IBM software that does the same thing the NetApp HUK config_mpath script made. IBM did nothing of this complex for VMware, so you will need to manually configure the preferred of all paths.

For CVS, specifically, I highly recommend to keep the same path for each LUN - usually using esxcfg-mpath you can set preferred paths for each LUN, and then set the preferred path using alternating LUN # s vmhba1 target1 and target2 to vmhba2 - so, for example, you have two ways to LUN0 - one for each target through each HBA (initiator/unique area on the switch); then set the path of privileged access to the target of vmhba1 because it is LUN0 - then to LUN1 you define the path preferred to vmhba2 - in this way you are (albeit manually) load balancing between the targets on the SVC.

The config_mpath of NetApp makes this process MUCH easier, because he goes and connects to the file server for you and find what is the path preferred to each unit logic of her number directly.

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.

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?

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.

Config host VMware Inconsitences

I ran Hugo Peters script to check the inconsitency fo my hosts.an noticed in a cluster of 10 serevrs two servers can see a LUN iD including, but not the data store...
I rescaned and updated the HBA without result
ABY ideas?

If you run esxcfg-mpath-l command in the console of the servers, you see the road as well?

iMessage can receive but not send

Just today, iMessage ceased to be able to send my model of MacBook Air mid-2013. I tried to disconnect and return with my Apple ID, have tried the reactivation of the computer from the phone settings and we tried switching where the iMessages originate. It worked very well for my iPhone, so I know this isn't my account itself that has problems. Can I do to solve this problem?

Hello

I'm sure if you deselected the iPhone number on the Mac version you would find that you don't see any iMessages.

(i.e. you are only to see synchronization copies of what is becoming the phone.)

Another Apple ID works?

Your Apple ID works in another Mac on your Mac user account?

The dial-up connection includes the use of the serial number of the Mac to provide a specific connection of device

If you go to the top of the Menu of the icon Apple left and about this Mac only shows the serial number?

If it is not there then you will need to take the Mac and Apple Store and put back it.

If another ID works then the application works correctly.

If your code does not work in another Apple ID then it's like most stuck to the Apple iMessages Server (device specific).

If this is the case you must phone Apple Support (Apple Care)

You have a problem with Apple which are free to set - ID stakeholders a level are driven Script and will try to ignore it.

Ask to speak to someone more important.

Even in this case some level 2s did not hear the question.

Politely, ask them to check the server iMessages and see if your use of the your Mac ID is blocked.

Ask them to reset it.

It will probably mean the engineers involved and statements to be between 24 hours and 5 days being used to solve this (according to other people who have posted on this).

command to get Lun information in ESX 3.5

All master to get information of LUNs in ESX 3.5 associated VMHBA0?

You can use the command and attached are the output you can check and compare too...

for you below should work...

esxcfg-mpath-lv | grep ^ disc | grep - v vmhba0

or

esxcfg-mpath-lv | grep ^ disc | grep - v vmhba0 | AWK '{print substr($3,14,33), $5, $2}' will give you joint out.

hope this will help...
