RDX 8000
Linux CentOS:
Use the following commands to install the iSCSI Initiator and Connect and Disconnect the RDX 8000 as an iSCSI
Target in Linux operating systems:
To Connect:
1. Install Open-iSCSI initiator by entering the following command:
# yum install iscsi-initiator-utils
For Ubuntu and Debian operating systems, enter the following command:
$ sudo apt-get install open-iscsi
2. Discover iSCSI Targets using the following command, replacing the variable IP address with the actual IP
address for your RDX 8000:
# iscsiadm -m discovery -t sendtargets [or st]-p ip address
For example:
# iscsiadm –m discovery –t st –p 192.168.64.103
The results will depend on the configured mode of the RDX 8000:
- JBOD – Eight iSCSI targets
- Tape Library mode – one iSCSI target.
3. Connect to the selected iSCSI target(s):
 To connect to all targets:
# iscsiadm -m node -L all
 To connect to an individual target, enter the following command, replacing target IQN name with the iSCSI
qualified name (IQN) of the target and replacing ip address with the RDX A8 IP Address:
# iscsiadm -m node -T target IQN name -p ip address --login
For example :
# iscsiadm –m node –T iqn.2011-05.com.quantum:RDX8000-0000BD-1 –p
192.168.646.103 --login
Once the target is connected, the Linux host can use the iSCSI disks as a normal disk. It appears under
/dev/sdx devices and can be formatted and mounted like a normal disk.
To Disconnect:
1. Use the following command, replacing target IQN name with the iSCSI qualified name (IQN) of the target and
replacing ip address with the RDX 8000 IP Address:
# iscsiadm -m node -T target IQN name -p ip address –-logout
5.5 Cartridge Ejection
The RDX 8000 is configured to ensure the integrity of the data written to the cartridges. For that reason, the
cartridges are put into the Ejection Protection mode when an
iSCSI connection is completed. This mode prevents the
user
from ejecting the cartridges using the front panel eject buttons or the Eject function in the RDX 8000. The user
can
work through the operating system to eject the cartridge using the Eject function.
The
RDX 8000 does have a Windows based Eject Service that can be installed to provide front-panel eject capability
while
an iSCSI connection is established. This service watches the data transfers and allows the transfer to
successfully complete before allowing the ejection of the cartridge. The service is
packaged with an RDX utility that
allows the user
to view specific details of the RDX cartridges. The service can be installed on each host that creates
an
iSCSI connection with the RDX 8000.
The
Eject Service/Utility can be downloaded from the RDX 8000 Web site at:
