Script to get Virtual machine RDM SCSI Controller & Bus Sharing Mode Report

[Narayanan_5245]

Hi Team,

Can anyone please help to suggest if we can have a script to pull the VM RDM SCSI Controller & Bus Sharing Mode along with host and cluster from the vCenter.

Thank you

Regards

Narayanan.

[LucD]

Yes, you can.

[Narayanan_5245]

Hi LuCD,

Used the below which you already suggested in other thread, but couldn't get the controller & sharing mode of the RDM disks. Can you help.

Get-VM | Get-HardDisk |

where {"RawPhysical","RawVirtual" -contains $_.DiskType -and

       "Physical","Virtual" -contains (Get-ScsiController -HardDisk $_).BusSharingMode} |

Select @{N='VM';E={$_.Parent.Name}},

    Name,

    FileName,

    CapacityGB,

    DiskType,

    ScsiCanonicalName,

    @{N='BusSharing';E={(Get-ScsiController -HardDisk $_).BusSharingMode}}

Regards

Narayanan.

You could do

Get-Cluster -PipelineVariable cluster |

Get-VMHost -PipelineVariable esx  |

Get-VM -PipelineVariable vm |

Get-HardDisk -DiskType RawPhysical,RawVirtual |

Select @{N='Cluster';E={$cluster.Name}},

    @{N='VMHost';E={$esx.Name}},

    @{N='VM';E={$vm.Name}},

    Name,

    @{N='HDSharingMode';E={$_.ExtensionData.Backing.Sharing}},

    @{N='Controller';E={

        $script:ctrl = Get-ScsiController -HardDisk $_

        $script:ctrl.Name  

    }},

    @{N='CtrlType';E={$script:ctrl.Type}},

    @{N='CtrlBusSharing';E={$script:ctrl.BusSharingMode}}

Works Perfectly LuCD. Great.

One additional request, Is it possible to include the HD Disk Compatibility mode (Physical) & Virtual device node (1:5) number along with this report as well.

Regards

Narayanan.

Try like this

Get-Cluster -PipelineVariable cluster |

Get-VMHost -PipelineVariable esx  |

Get-VM -PipelineVariable vm |

Get-HardDisk -DiskType RawPhysical,RawVirtual |

Select @{N='Cluster';E={$cluster.Name}},

    @{N='VMHost';E={$esx.Name}},

    @{N='VM';E={$vm.Name}},

    Name,DiskType,

    @{N='HDSharingMode';E={$_.ExtensionData.Backing.Sharing}},

    @{N='Controller';E={

        $script:ctrl = Get-ScsiController -HardDisk $_

        $script:ctrl.Name

    }},

    @{N='vDevNode';E={

        "{0}:{1}" -f $script:ctrl.ExtensionData.BusNumber,$_.ExtensionData.UnitNumber

    }},

    @{N='CtrlType';E={$script:ctrl.Type}},

    @{N='CtrlBusSharing';E={$script:ctrl.BusSharingMode}}

Got the expected Output and made it very easy. Thank you for your support LuCD. Genius!!.

One last request, if this possible can we able to run this script on 2 Center servers (different credentials) simultaneously and make it to single report.

I have tried to ran Connect-VI server vCenter1, vCenter2 but the last one only taking for the consideration and pulling a report for the second vCenter server.

Set-PowerCli configuration to Multiple mode & All users, session as well, no luck. Please advise.

Regards

Narayanan.

Did you check you actually have 2 connections open?
What is in $global:defaultVIServers?

[Narayanan_5245]

seems the first session getting overridden while connecting the second vCenter server. Please find below the output

Windows PowerShell

Then it looks as if the DefaultViServer mode is still set to 'Single'.
Check with Get-PowerCLIConfiguration, and eventually change with Set-PowerCLIConfiguration.

Note that these settings have different scopes.

[Narayanan_5245]

Set the mode to Multiple but got the only output of one vCenter server other throws error.

Do you get the same error when you do a simple Get-VM from the PS prompt?

[Narayanan_5245]

Hi LuCD,

Tried with other 2 vCenter servers that have VMs with RDMs and could get the report of both vCenter reports.

Maybe earlier it's not reported due to one of the vCenter doesn't have any VMs attached with RDMs.

But curious to understand the below error while running the script for multiple vCenter servers.

PowerCLI C:\compaq> .\RDMLUN8.ps1

No clue why that happened on that specific vCenter.
Did you try the Get-VM on that vCenter I asked earlier?

[Narayanan_5245]

yes LuCD. Get-VM works fine and able to get both vCenter vms without any error.

Regards

Narayanan.

[Narayanan_5245]

if I try to run the script, getting the output details but getting "Exception has been thrown by the target of an invocation".

Regards

Narayanan.

[LucD]

And does this work in both vCenters?

Get-VM | Get-HardDisk -DiskType RawPhysical, RawVirtual

[Narayanan_5245]

yes LuCD. Get-VM | Get-HardDisk -DiskType RawPhysical, RawVirtual command works fine and getting the output of both the vCenter virtual machines with RDM attached.

[LucD]

Then I have no clue why that error is happening on one of your vCenters

[Narayanan_5245]

LuCD,

Thanks for checking and all the help.

Just realized the error is getting throwing is due to PowerCLI version VMware PowerCLI 6.5 Release 1 build 4624819. The same script tried in the latest version (VMware PowerCLI 10.1.0 build 8346946) and works without any errors.
