DRIVES NOT LISTING ON SSMS WHILE CREATING MAINTENANCE PLAN

The Recently added Luns(added as drives from windows) were not getting listed in the cluster SQL Server.

When I tried backing up the database through scripts mentioning the newly added drives the backup was successful.When We we tried to create  a maintenance plan , I was not able to see the drives from there.

FROM SSMS New query window I issued XP_FIXDRIVES , I was able to see all the drives including the newly added drives .

To fix the issue ,

• From the Cluster administrator brought the newly created drives offline.
• Brought the SQL Services offline.
• From the properties of SQL Services -->Dependencies -->Modify-->Added the drives.
• Brought the SQL Services online.
• Disconnected the Management Studio and connected back to Management  Studio.

Now I again tried to create maintenance plan, I was able to see the Drives Successfully.
