Mixed Mode (Raid And Jbod) - HP MR Gen10 Plus User Manual

Mixed mode (RAID and JBOD)

Mixed mode (RAID and JBOD)
Mixed mode allows for any drive to be a member of a logical drive (logical volume or RAID volume), unconfigured and hidden from the
operating system, or in a JBOD drive state which exposes the drive to the host operating system as a physical drive.
When you power down a controller and insert a new drive and if the inserted drive does not contain valid DDF metadata, the drive
status is listed as JBOD (Just a Bunch of Drives) when you power on the system again. When you power down a controller and insert a
new drive and if the drive contains valid DDF metadata, its drive state is Unconfigured Good. A new drive in the JBOD drive state is
exposed to the host operating system as a standalone drive. You cannot use JBOD drives to create a RAID configuration, because they
do not have valid DDF records. Therefore, you must convert JBOD drives to unconfigured good drives.
The MR Storage Administrator includes options for converting JBOD drives to an unconfigured good drive, or an unconfigured good
drive to a JBOD drive.
