Possibilites to Code ESX Shell Commands to all ESXi Hosts

Hello,

our Storage configuration need to be update in order to funktion better, so we got a list of commands we need to apply.

 

Is it possible to script this? We have like 500 Esx Hosts. Becaus we need to apply Esxshell commands to EsxHosts  and PowerCli over the vCenter

 

esxcli system module parameters set -p ql2xmaxqdepth=32 -m qlnativefc

Get-AdvancedSetting -Entity EsxHost -Name VMFS3.UseATSForHBOnVMFS5 | Set-AdvancedSetting -Value 0 -Confirm:$false

for i in `esxcfg-scsidevs -c | awk '{print$1}' | grep naa.600 `; do esxcli storage nmp psp roundrobin deviceconfig set --type=iops --iops=1 --device=$i; done

Get-AdvancedSetting -Entity $esx -Name Disk.DiskMaxIOSize | Set-AdvancedSetting -Value 256 -Confirm:$false | Out-Null

esxcli storage core device set --device device_uid --queue-full-threshold 32 --queue-full-sample-size 8

Not too sure what the actual question is.

The esxcli commands you can run via the Get-EsxCli cmdlet. There are numerous examples on how to do this in this community, just use the handy Search functionality.

The *-AdvancedSetting cmdlets are PowerCLI cmdlet, not sure what the question is here?

ok it is possible that was the Question and now it is how do I do this for like

for i in `esxcfg-scsidevs -c | awk '{print$1}' | grep naa.600 `; do esxcli storage nmp psp roundrobin deviceconfig set --type=iops --iops=1 --device=$i; done

I dont even know how to make it into a Get-ESXcli and then I need so do this all for every ESX and all commands how can I do this.

It is not clear to me if that last esxcli command is for all device or only the ones where the CanonicalName starts with 'naa.600'.

If it is for all LUNs, it will require a separate loop with the the Where-Object clause.

 

$sMod = @{
    module = 'qlnativefc'
    parameterstring = 'ql2xmaxqdepth=32'
}

Get-VMHost -PipelineVariable esx |
ForEach-Object -Process {
    $esxcli = Get-EsxCli -VMHost $esx -V2
    $esxcli.system.module.parameters.set.Invoke($smod)
    $esxcli.storage.core.device.list.Invoke() | where{$_.Device -match "^naa.600"} |
    ForEach-Object -Process {
        $sRR = @{
            device = $_.Device
            type = 'iops'
            iops = 1
        }
        $esxcli.storage.nmp.psp.roundrobin.deviceconfig.set.Invoke($sRR)
        $sDev = @{
            device = $_.Device
            queuefullthreshold = 32
            queuefullsamplesize = 8
        }
        $esxcli.storage.core.device.set.Invoke($sDev)
    }
    
    Get-AdvancedSetting -Entity $esx -Name VMFS3.UseATSForHBOnVMFS5 | 
    Set-AdvancedSetting -Value 0 -Confirm:$false | Out-Null
    Get-AdvancedSetting -Entity $esx -Name Disk.DiskMaxIOSize | 
    Set-AdvancedSetting -Value 256 -Confirm:$false | Out-Null
}

Hi,

Those parameters, like NMP SATP rules are set per Vendor instead of per LUN.

This is an example for PURE storage.

 

 

Get-VMhost | Get-EsxCli –V2 | % {$_.storage.nmp.satp.rule.add.Invoke(@{description='Pure Storage FlashArray SATP';model='FlashArray';vendor='PURE';satp='VMW_SATP_ALUA';psp='VMW_PSP_RR'; option='iops=1'})}

 

 

Most of the storage providers shared their best practices with the relevant parameters.

Did you check that the following line is returning something?

$esxcli.storage.core.device.list.Invoke() | where{$_.Device -match "^naa.600"}

I think the error is clear, the value on the threshold parameter must be smaller or equal than the value on the samplesize parameter.
