PowerShell Specify L2 Cache Setting

[zxu]

Is there a way to specify L2 cache setting/path when creating a device (either local or HA, disk in WT mode with L2 or LSFS)? Additionally, how to turn on dedupe on/off when creating HA-LSFS? There seems to be some disparity between what can be done via PowerShell vs GUI.

Hello, zxu, and thank you for your question. You can find more info on how to manage L2 flash cache here in this article:

And, regarding your question about deduplication on LSFS device. Please find a folder with PowerShell samples scripts. By default it is located here:
C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell\
There is a script called CreateHA_LSFS.ps1 You can enable deduplication, simply adding to the script this command:
Add-DDDevice -DeduplicationEnabled $true
Feel free to edit the sample script according to your needs.

Thanks! Can you use Add-DDDevice to add HA LSFS? The Create-HALSFS is using Add-HADevice. I don't see DeduplicationEnabled an option in Add-HADevice. Is this an undocumented option in Add-HADevice?

Please take a look at CreateDD.ps1 script. I hope this is what you need. Just add "-DeduplicationEnabled $true" option.
P.S. We will release new StarWind version soon, with updated and newly added samples.
