Configure iSNS Server in an iSCSI Initiator with PowerShell

This will just be a very quick post today.

Configuring an iSCSI Initiator to use an iSNS Server is fairly easy using the iSCSI configuration utility:

ss_isns_guiinitiatorconfig

But lets face it, that’s no fun and it really doesn’t fit well when when we have to configure 10’s or 100’s of initiators or we’re using Server Core. Not to mention that this is something we’d really want to do with Desired State Configuration. Besides, this is a PowerShell blog.

It is easy enough to configure iSCSI Targets to register with an iSNS Server:

But unfortunately I couldn’t find any documentation on how to do this on an iSCSI Initiator. But after a little bit of digging around WMI I found the appropriate class:

MSiSCSIInitiator_iSNSServerClass

So, to add the iSNS Server to the iSCSI Initiator:

Notice that the WMI Class argument name for the setting the iSNS Server name in an iSCSI Initiator is different (iSNSServerAddress) compared to setting it for an iSCSI Target (ServerName).

To list the currently set iSNS Servers:

ss_isns_getlistservers

And if you need to remove an iSNS Server from the iSCSI Initiator:

Pretty easy right?

In a few weeks I plan to integrate iSNS registration with my iSCSI DSC Resources (also available on PowerShell Gallery) so that the whole process of registering iSCSI Initiators and Targets with iSNS is just a little bit easier.

Thanks for reading.
