When you add a new type of drive to an Oracle FS System, the system must be able to determine the Storage Class to which the drive type belongs. Uploading the Oracle-provided XML file that maps all supported drive types to appropriate Storage Classes enables the addition of the type of drive to succeed.
When you replace or add a Drive Enclosure that contains a new type of drive, the Oracle FS System rejects the drives unless the new drive type is already known to the system and is mapped to a specific Storage Class.
To prevent the new type of drives from being rejected, obtain from Oracle the latest XML file that maps this new drive type to an appropriate Storage Class and then upload the file into the system. An alternative is to perform a software update using a software package that contains the new mapping file.
