The following example shows the Summary screen after the Capacity Upgrade Kit has been installed
and the HP D2D Backup System has two shelves with 24 disks.
Planning for the Capacity Upgrade
IMPORTANT: The HP D2D Backup System will be offline while the Capacity Upgrade Kit is
installed and the expansion process is completed to expand to the increased shelf capacity. This
means that the HP D2D Backup System cannot be used for backup or replication during the
expansion process.
It is important to allow sufficient downtime for the expansion process to complete. Depending upon
the amount of data on the original system, this can take from 5 minutes to more than 12 hours to
complete with the HP D2D4100 Series. With the HP D2D4300 Series, it could be considerably
longer (up to 36 hours) depending upon the shelf configuration and the amount of data.
Make sure that host users are aware that the system will not be available for backup and restore
and check to see how any scheduled jobs, such as replication and tape backup, may be affected.
An overview of the capacity upgrade process
1. Install the rails for the Capacity Upgrade Kit, which should be located directly below or above
the HP D2D Backup System (Shelf 0 or Internal), see Chapter 2.
2. Install the Capacity Upgrade Kit (HP D2D4100 Series: Shelf 1 or HP D2D4300 Seies: Shelf
1/2/3), see Chapter 2.
3. Connect the Capacity Upgrade Kit (HP D2D4100 Series: Shelf 1 or HP D2D4300 Series:
Shelf 1/2/3) to the HP D2D Backup System (Shelf 0 or Internal), see Chapter 2.
4. Power on the Capacity Upgrade Kit, see Chapter 2.
5. Make sure you know both the HP entitlement order number (supplied with the Capacity Upgrade
Kit) and the HP D2D serial number (found on the label on the top of the unit). Obtain a License
To Use (LTU) from the HP Licensing website, see Chapter 3. If you are installing several upgrade
kits with an HP D2D4300 Series Backup System, be sure to obtain all LTUs before step 6.
