Configuring OVM Storage
Before you start, logon to the OVM Server and add your NFS and / or iSCSI fully qualified domain named servers to the /etc/host file to avoid hitting OVMRU_000082E.
Can Not Add NFS Server To Oracle VM Manager: OVMRU_000082E Either the hostname or IP address is invalid (Doc ID 2294262.1)
Navigate to the Storage tab, from here we can configure SAN Servers (Block) and File Servers (NFS)
To add NFS Storage, select File Servers and click the folder icon with the green plus, this should show the Discover File Server.. tag.
Enter NFS Server Name, storage network IP address, Description
Move OVM server(s) to Selected Admin Server(s) and click Next.
Move OVM server(s) to Selected Refresh Server(s) and click Next.
Block Storage (iSCSI)
Enter SAN Server Name and Description, as I am planning to use iSCSI there is no need to change Storage Type, click Next.
Check you do not have any leading or trailing spaces in your description, otherwise you will encounter an OVMRU_000096E error.
OVMRU_000096E Cannot set attribute Description of object IscsiStorageArray to value [ xxx ]. Leading or trailing spaces are not allowed.
Enter Access Host(s) and Click Next.
Repeat above step for multipathing, and then click Next
Select OVM Server(s) and click Next
Select the Default access group and click the pencil icon to edit Access Group.
Click on the Storage Initiators tab and move the generic Oracle storage initiator to Selected Storage Initiators and click OK.
Now click Finish to complete the set-up.Follow @RonEkins
