About adding 2U12 storage shelves to an operational appliance

The NetBackup 5230 Appliance supports up to four storage shelves. The following
scenarios define the supported and unsupported configurations.
Configurations
The following scenarios define the supported and unsupported configurations.
You can add up to four 2U12 shelves to a standalone NetBackup 5230 Appliance
■
that has no storage shelves attached.
You can add 2U12 shelves to an appliance that already has at least one 3U16
■
shelf for a total of four shelves. In doing so, you must connect the 2U12 storage
shelf to the last daisy-chained 3U16 storage shelf that is connected to the
appliance.
For example, NetBackup 5230 Appliance + 3U16 24TB Storage Shelf + 3U16
24TB Storage Shelf + 3U16 36TB Storage Shelf + 2U12 49TB Storage Shelf.
In addition, attaching a 2U12 storage shelf to a 3U16 storage shelf requires a
SAS3-to-SAS2 cable to connect the shelves. Finally, the SAS3 data transfer
rate of the 2U12 storage shelf drops to match the SAS2 data transfer rate of
the 3U16 storage shelf.
You cannot add any storage shelves to an appliance that already has four
■
connected shelves.
Note: Veritas does not support adding additional storage shelves to an existing
system without first shutting down the NetBackup 5230 Appliance and all attached
storage shelves.
See "Shutting down the appliance"
