The red area indicates the threshold capacity. The system will send warning messages to email recipients
that the disks are reaching capacity. The Disk Usage icon on the Summary page will also indicate that
disk space is running out and the Disk Capacity LED will flash.
You cannot add physical disk space, but you may be able to create some space. Options for creating
space, if the disks start to get full, include:
•
Review your backup jobs to see if you can reduce the size of backup or retention time.
•
Use the backup application job settings to overwrite or erase data.
•
Export a cartridge to tape, see
Using the Web Management interface to copy/export/import cartridges
Autoloader 1/2/...: This is the amount of data backed up to each device. (This does not include the
default 2 GB space committed for each cartridge slot. If no data has been backed up, the value is 0
GB). Each autoloader and tape drive is shown separately.
Physical disks
This section provides information about the physical disks. If you need to replace a disk, it is very
important to obtain the serial number and the physical location of the failed disk from this page before
you replace it.

Serial No:
This is the serial number of the disk. Always make a note of this before replacing
a failed disk.

This is the firmware version of the disk. It may be useful for troubleshooting and
when replacing a disk.

iSCSI (Status)
This page shows the iSCSI details for all the devices that are configured on the HP D2D Backup System. It
also shows any active connections. All available devices are shown in the top half of the page. Click on
Select to view more detailed information on that device in the bottom half of the screen.
This page is mainly for information and is useful in troubleshooting. The Edit facility is provided only for
users who need to enable authentication. It displays additional fields in the iSCSI Authentication section.
We do not recommend that you use authentication, but it will be necessary if you have enabled the Secret
feature on the General tab in the iSCSI Initiator. Click Edit to make the fields editable.
If a device is showing as not connected, this indicates that the iSCSI Initiator on the host has not logged
on. Log on using the iSCSI Initiator and set the device as a Persistent Target for that host. This ensures that
it will automatically log on again, if the host is rebooted. See “
