NOTE:
Certain backup applications require their own drivers for both the tape device and medium changer. For
many applications these are installed automatically during the software installation process. If the backup
software is already installed, you may need to update manually the drivers after installing the StoreOnce
System.
After installation, the StoreOnce System does not appear as a device under My Computer and it is not
mapped to a drive letter. The host machine requires a backup application to back up and restore data.
However, if drivers are installed, the backup system can be viewed as a tape drive and medium changer
from the Device Manager.
NOTE:
For a Fibre Channel StoreOnce system, a new “unknown” device will be discovered in Device Manager.
This device is required only to ensure that a Fibre Channel target exists as LUN 0 in the SAN. No
functionality is provided by this device and no driver is required. Note that this device will be replaced by
the Catalyst Over Fibre Channel initiator device if CoFC is configured.
iSCSI Initiator (StoreOnce VTL)
iSCSI is a protocol for sending SCSI commands via Ethernet. It defines how SCSI packets are translated
to Ethernet packets and connects to the required devices. An iSCSI initiator may be hardware or software
and should be running on each host. If the host does not have an iSCSI initiator, it will not be able to
connect to the library configured on the StoreOnce System and will not be able to perform backups.
For Linux and UNIX operating systems an iSCSI initiator is embedded in the operating system. Please
refer to the StoreOnce System Linux and UNIX Configuration Guide for further information. Make sure
that you have downloaded the latest operating system patches before you configure your system.
For Windows systems the Microsoft iSCSI initiator is required to connect to any Virtual Tape Libraries
created on the StoreOnce System. The iSCSI initiator ships with later versions of Microsoft Windows, but
not with Windows 2003 or earlier. So, if required, it must be retrieved from the Microsoft website.
NOTE:
With some versions of Windows the iSCSI initiator service is not started by default. This component must
be configured manually by the user to run on startup. Refer to Windows documentation for more details.
