Confirm the eql pssnapin is available, if not do the import again.

Get-PSSnapin -Registered

Once the group is added (new-eqlgroupaccess), modify to add the VSS information, use Set-EqlGroupAccess for example

Set-EqlGroupAccess -VSSUserName vssadmin -VSSPassword vssadmin2012

Ensure you excluded the subnets that are not on the iSCSI network in ASM (MPIO Settings)

In VMM Under Arrays find all the registered groups, and right click to assign managed pools, then after, you can create logical units in the pools

When i "Set-EqlGroupAccess -VSSUserName vssadmin -VSSPassword vssadmin2012", it says group name is not mentioned, so i modify command as "Set-EqlGroupAccess -groupname mygrp -VSSUserName vssad -VSSPassword 123", then it say GROUP NAME IS NOT REGISTERED
