# xtremlib

xtremlib is a PowerShell Module that wraps interactions with the XtremIO RESTful API This is the 4.0 (for use with XIOS 4.0 +) module. Much has changed since the older release, if you want to use the previous version it is still available under releases. The old release will be compatible with XIOS 3.X and 4.X, but this release will only work with 4.0+. Due to significant API changes, this module has undergone alot of rewrite so commands have changed, with alot of new functionality. If you use the old module for automation, you should still be able to use it even after upgrading to 4.0... but new features will only be available here.

Looking for testers! If you work at EMC or are a customer with XtremIO and want an easy way to contribute to the {Code} community, this would be huge!

Upcoming changes

  • Ability to leverage new 4.0 capabilities (CGs, Snapshot Sets, Snapshot Refresh, Perf metrics, etc)
  • Allowing for object piping between cmdlets, positional parameters, and other 'PowerShell' things
  • Implementation of v2 API as well as filters for selecting only information you want.
  • Ability to run against XMS managing more than one system
  • And more!


  • Looking for testers!
  • For feature request, please raise an issue
  • For bugs, please, raise an issue


Installing the Module

Place all contents into your PowerShell Module folder, or use Import-Module


Run Get-XtremHelp in PowerShell for list of commands and examples. Use the xtremlib functions to get information from and make changes to XtremIO. Most function switch input is case-sensitive, so assume that when entering names and information capitalization must match. One-time credential setting is now possible using New-XtremSession. Credentials can also be specified for each command. Here are some examples (the below use special formatting for output, you can use your own custom object formatting):

First generate and store secure credentials:

New-XtremSecureCreds -path C:\temp

Then start an XtremIO session (this stores creds (encrypted pw)) as global vars for the PowerShell session:

New-XtremSession -XmsName -XtremioName xio10 -CredLocation C:\temp

4.0 Introduced the ability for a single XMS to manage multiple XtremIO clusters. Even if you only manage one cluster, it's mandatory in this module to include the name. If you aren't sure of the name, run this:


Get All Cluster Statistics

Get-XtremCluster xio11

Or you can return specific properties like this:

Get-XtremCluster -Properties iops,logical-capacity-in-use

Retrieve a list of all volumes:


Or retrieve all volumes including certain properties. Most GET commands allow you to supply a properties list:

Get-XtremVolumes -Properties iops,wr-bw,vol-id,creation-time

Retrieve a specific volume

Get-XtremVolume -VolumeName navi

Positional parameters exist for most GET/DELETE commands, as well as less complex PUT/POST commands:

Get-XtremVolume navi

Create a Volume

New-XtremVolume -VolumeName navi -VolumeSize 1048g
New-XtremVolume navi 1048g

Edit a Volume

Edit-XtremVolume -VolumeName navi -ParameterToModify vol-name -NewValue navi2
Edit-XtremVolume -VolumeName navi -ParameterToModify vol-size -NewValue 16g

Return list of all snapshots


Return list of all snapshot sets


Create a snapshot set of volume(s), consistency group, volumes with certain tag(s), or snapshot set

New-XtremSnapshot -ParentType volume-list -ParentNames navi,navi1 -SnapshotSetName navisnaps
New-XtremSnapshot -ParentType volume-list -ParentNames navi -SnapshotSetName navisnap
New-XtremSnapshot -ParentType consistency-group-id -ParentNames navicg -SnapshotSetName navisnaps
New-XtremSnapshot -ParentType tag-list -ParentNames PROD,PRODUCTION -SnapshotSetName navisnaps

Create a snapshot of a volume, consistency group, or snapshot set and refresh a volume, consistency group, or snapshot set

New-XtremSnapshotRefresh -ParentType from-volume-id -ParentName navi -RefreshType to-snapshot-set-id -RefreshName navisnaps -NewName navisnaps1
New-XtremSnapshotRefresh -ParentType from-consistency-group-id -ParentName navicg -RefreshType to-snapshot-set-id -RefreshName navisnaps -NewName navisnaps1
New-XtremSnapshotRefresh -ParentType from-snapshot-set-id -ParentName navisnaps -RefreshType to-consistency-group-id -RefreshName navicg -NewName navicg1

Delete a volume or snapshot set

Remove-XtremVolume -VolumeName navi

This also deletes a snapshot if you like it more

Remove-XtremSnapshot -SnapshotName navisnap

Remove a snapshot set

Remove-XtremSnapshotSet -SnapshotSetName navisnapset
Remove-XtremSnapshotSet navisnapset

How to Retrieve Historical Perf/Capacity Statistics

This was a new feature in 4.0, and because there are alot of options this is getting its own section. The command to be ran is like this:

Get-XtremPerformance -ObjectType -Granularity -ObjectList -Properties -FromDateTime -ToDateTime 

These are the possible ObjectTypes:

SnapshotGroup, Initiator, Target, XEnv, DataProtectionGroup, Volume, Cluster, Tag, InitiatorGroup, SSD, TargetGroup, Xms

FromDateTime and ToDateTime are optional - default time range is 30 days from the current date. If you input specific ranges, they must be parseable by Get-Date, such as the below examples:

Get-XtremPerformance -ObjectType Cluster -Granularity one_day -FromDateTime '08/28/2015' -ToDateTime '09/4/2015'
Get-XtremPerformance -ObjectType Cluster -Granularity one_minute -FromDateTime '09/4/2015 08:00' -ToDateTime '09/4/2015 10:00'
Get-XtremPerformance -ObjectType Cluster -Properties avg__iops,avg__bw -Granularity one_hour -FromDateTime '09/4/2015 08:00' -ToDateTime '09/4/2015 11:00'

Object-List is optional. It is a comma separated list of instances of the object you selected...For instance, a list of volumes:

Get-XtremPerformance -ObjectType Volume -Granularity one_day -Properties avg__bw -ObjectList (Get-XtremVolumes).name
Get-XtremPerformance -ObjectType Volume -Granularity one_day -Properties avg__bw -ObjectList navi,navi1,navi2

Properties are optional (default is ALL). These are the possible properties for the 'Cluster' object:


As you can see, there are a ton, and they vary from object to object. To see the properties for your desired object, do this and check the properties that come back:

Get-XtremPerformance -ObjectType <objecttype> -Granularity one_minute

Then run the command with only a subset of the properties returned in the previous command:

Get-XtremPerformance -ObjectType Cluster -Properties avg__iops,avg__bw

The returned object has 4 properties: counters, members, links, and granularity. You probably want to do something with this data, so understanding the layout is pretty key.

'Members' are your columns, such as 'timestamp', 'guid', 'name', 'index', 'avg__iops', 'avg__bw'. Take note of the double '_'

'Counters' contains many objects, and each one contains values for each of the 'Members' in order (essentially, statistics at a particular time stamp) 

You can think of 'Members' as the columns, and 'Counters' as the rows. Powershell's Export-CSV won't just handle this object the way you'd expect without some specialized object formatting. Since I figure that many people will like to use this, I made module command that will do this for you. So putting it all together:

Get-XtremPerformance -ObjectType Cluster -Properties avg__iops,avg__bw | Export-XtremCSV -ExportPath C:\temp\performance.csv

That will create a CSV that you can use to create graphs or whatever. I've even taken care of the epoch conversion for you (the timestamps are Unix Epoch time).

####Capacity Trending Examples If you wanted to get a report showing the used logical/physical capacity and the dedupe/compression over a 3 month period, this would work:

Get-XtremPerformance -ObjectType Cluster -Properties avg__ud_ssd_space_in_use_in_base10,avg__logical_space_in_use,avg__dedup_ratio,avg__compression_factor -Granularity one_day -FromDateTime '06/4/2015 08:00' -ToDateTime '09/4/2015 10:00' | Export-XtremCSV -ExportPath C:\temp\capacity.csv

A minute later, you can make charts like this: Dedupe/Compression

Or like this: Physical/Logical Capacity
