Tag: PowerCLI

Here’s the short and sweet for configuring the best practice SATP rule for XtremIO storage on ESXi 5.5 using PowerCLI (5.8 Release 1, in my case). I can’t claim any credit beyond aggregation and adaptation: the parameters are from the XtremIO user guide and the script comes from VirtuallyHyper.com (thanks!). See my earlier post about the SATP rule itself and how to manually implement it: VMware ESXi Round Robin NMP IOPS=1.

#Variables
$cluster = "Production"

foreach($esx in Get-Cluster $cluster | Get-VMHost){
$esxcli = Get-EsxCli -VMHost $esx
# List XtremIO SATP rules
# $esxcli.storage.nmp.satp.rule.list() | where {$_.description -like "*XtremIO*"}
# Create a new SATP rule for XtremIO
$result = $esxcli.storage.nmp.satp.rule.add($null,"tpgs_off","XtremIO Active/Active",$null,$null,$null,"XtremApp",$null,"VMW_PSP_RR","iops=1","VMW_SATP_DEFAULT_AA",$null,"vendor","XtremIO")
# List XtremIO Rules
# $esxcli.storage.nmp.satp.rule.list() | where {$_.description -like "*XtremIO*"}
Write-Host "Host:", $esx.Name, "Result", $result
}

Storage Technology Virtualization

PowerCLIScripting and automation are ashamedly new territories for me. I’ve heard enough clarion calls to grow and develop personally and professionally, though, that I know I have to gain ground here. Hopefully this is the first step in building my knowledge base of such tools.

In this entry, I need to solve for two configuration tasks.

Syslog

First, I am concluding an evaluation of Splunk and need to reset my vSphere ESXi 5.5 hosts’ syslog global log hosts to only our existing syslog server. My inclination was to click through the vSphere Client and change it host by host, as it would have taken less time than it has to write the words in the post so far. However, as I am in search of a new syslog solution, possibly VMware LogInsight, I know I will need to do this again.

BP1: Get-View returns full copy of the server-side object
– otherwise the get- commands only return a subset of the properties

BP2: Finding Properties
– what you see is not what is there
– – can edit the .ps1xml files to change returned properties
– use Get-Member to return all of the properties
– ex. Get-VMHost | Get-Member
– complex (nested) objects
– – Select-Object -ExpandProperties
– – Get-Member in a loop
– – Format-Custom Depth

BP3: Make Your Own Properties
– use the New-VIProperty cmdlet
– adds a CodeProperty to the object
– valid until Remove-VIProperty or end of session
