Here is a quick script that will add an additional volume to your ESX environment.

It requires the Nimble PowerShell Module and PowerCLI

 

 

#Connect to VCenter and Nimble Array

Connect-VIServer -Server $vcenter

Connect-NSArray -SystemName $ip -Password $password

#define settings

$vmhost = get-vmhost $VMHostName

$volumeName = "Nimble04"

$InitGroupName = "ESX"

$Size = 2tb

 

 

# Create a new volume

$vol = New-NSVolume -Name $volumeName -Size $Size -MultipleInitiator -PerformancePolicy 'VMware ESX 5'

# Provide the ESX hosts access to that volume

Add-NSInitiatorGroupToVolume -InitiatorGroup $InitGroupName -Volume $volumeName -Access Both

# Find the volume on the ESX host

$target = $vol.serialnumber

Get-VMHost -Server $nvm | Get-VMHostStorage -RescanAllHba

 

 

$lun = Get-ScsiLun -VmHost $vmhost -CanonicalName "eui.$target"

$canonicalName = $lun.canonicalname

# Create the new DataStore

New-Datastore -Name $volumeName -Path $canonicalName -Vmfs -VMHost $vmhost

 

 

Get-VMHost | Get-VMHostStorage -RescanAllHba

# Make sure the Multipathing is setup correctly (RoundRobin)

get-vmhost | Get-ScsiLun -CanonicalName $canonicalName | ?{$_.multipathpolicy -ne "RoundRobin"} | Set-ScsiLun -MultipathPolicy RoundRobin
