You have a server named LON-DC1 that runs Windows Server 2012 R2. An iSCSI virtual disk
named VirtualiSCSI1.vhd exists on LON-DC1 as shown in the exhibit. (Click the Exhibit button.)
You create a new iSCSI virtual disk named VirtualiSCSI2.vhd by using the existing itgt iSCSI target.
VirtualiSCSIl.vhd is removed from LON-DC1.
You need to assign VirtualiSCSI2.vhd a logical unit value of 0.
What should you do?
A.
Modify the properties of the itgt ISCSI target.
B.
Modify the properties of the VirtualiSCSI2.vhd iSCSI virtual disk.
C.
Run the Set-VirtualDisk cmdlet and specify the -Uniqueld parameter.
D.
Run the iscsicli command and specify the reportluns parameter.
Explanation:
The virtual disk has the option to change the lun ID, no other option available in the answers appear
to allow this change.
Note: Logical unit numbers (LUNs) created on an iSCSI disk storage subsystem are not directly
assigned to a server. For iSCSI, LUNs are assigned to logical entities called targets.
I think A
https://technet.microsoft.com/en-us/library/gg232626(v=ws.10).aspx
In that Technet article:
The option to change the LUN of a virtual disk is only available when you view the virtual disk Properties from the Devices node in the Microsoft iSCSI Software Target console.
answer is B
B is right.
You can Do this in powershell:
>Add-IscsiVirtualDiskTargetMapping -targetname MYTarget -path MYPATH -LUN NEWNUMBERLUN
B is correct.
From Exam Ref 70-412, Objective 2.3: Configure and optimize storage, page 135.
The properties dialog box of the iSCSI virtual disk allows you to modify the LUN value assigned
to the disk.
Tested in my lab and it cannot be B.
> create a new iSCSI virtual disk named disk1.vhd
> create a new iSCSI virtual disk named disk2.vhd
> check the properties of each disk. disk1 = lun0, disk2 – lun1
> delete disk1
> open the properties of disk2 and attempt to modify the lun from 1 to 0
> get error >>> LUN 0 conflicts with another virtual disk assigned to the same target
The iSCSI target properties will not show an option to modify the LUN ID.
iscsicli reportluns can not modify the ID http://windowcmc.com/q.php?q=iscsicli-manual
So that only leaves C…
