Making a Windows application-managed snapshot available on a server in a Microsoft
cluster
Use this procedure to make an application-managed snapshot available on servers that are in a
Microsoft cluster.
NOTE: We recommend contacting Customer Support before performing this procedure.
1. Disconnect the iSCSI sessions.
2. Do one of the following (based on what you need to do with the application-managed
snapshot):
•
Convert temporary space.
•
Create a SmartClone.
•
Promote a remote volume to a primary volume.
◦
Failover/Failback Volume Wizard and selecting the “Failover the Primary Volume
to the Selected Remote Volume Below” option.
◦
Edit Volume and changing a remote snapshot to a primary volume.
3. Connect the iSCSI sessions to the new target volume.
4. Launch Windows Logical Disk Manager.
5. Bring the disk online.
6. Open the system event log and find the IDs for the disks you are working with.
The disks will have new disk IDs. The log will show errors for the disks, along with the IDs the
cluster was expecting to see for each disk.
7. Open a Windows command line and run
diskpart.exe
.
8. List the disks that appear to this server by typing the command
list disk
.
9. Select the disk you are working with by typing
select disk #
(where # is the corresponding
number of the disk in the list).
10. Display the options set at the disk level by typing
detail disk
.
If the disk is listed as read-only, change it by typing
att disk clear readonly
.
The details show the expected ID for each disk. If the server is running Windows 2003, see
Microsoft KB 280425 for how to change the disk IDs.
11. On Windows 2008 and later, change the disk ID to the expected ID by typing
uniqueid
disk ID=[expected_ID]
(where [expected_ID] is the corresponding number of the disk
in the list).
12. Select the volume you are working with by typing
select volume #
(where # is the
corresponding number of the volume in the list).
