Using Your Tape Gateway
Connecting to a Linux Client
The following procedure shows a summary of the steps that you follow to connect to an RHEL client.
To connect a Linux client to VTL devices
1. Install the iscsi-initiator-utils RPM package.
You can use the following command to install the package.
sudo yum install iscsi-initiator-utils
2. Make sure that the iSCSI daemon is running.
For RHEL 5 or 6, use the following command.
sudo /etc/init.d/iscsi status
For RHEL 7, use the following command.
sudo service iscsid status
3. Discover the volume or VTL device targets defined for a gateway. Use the following discovery
command.
sudo /sbin/iscsiadm --mode discovery --type sendtargets --portal [GATEWAY_IP]:3260
The output of the discovery command looks like the following example output.
For volume gateways: [GATEWAY_IP]:3260, 1 iqn.1997-05.com.amazon:myvolume
For tape gateways: iqn.1997-05.com.amazon:[GATEWAY_IP]-tapedrive-01
4. Connect to a target.
Make sure to specify the correct [GATEWAY_IP] and IQN in the connect command.
Use the following command.
sudo /sbin/iscsiadm --mode node --targetname iqn.1997-05.com.amazon:[ISCSI_TARGET_NAME]
--portal [GATEWAY_IP]:3260,1 --login
5. Verify that the volume is attached to the client machine (the initiator). To do so, use the following
command.
ls -l /dev/disk/by-path
The output of the command should look like the following example output.
lrwxrwxrwx. 1 root root 9 Apr 16 19:31 ip-[GATEWAY_IP]:3260-iscsi-
iqn.1997-05.com.amazon:myvolume-lun-0 -> ../../sda
We highly recommend that after you set up your initiator you customize your iSCSI settings as
discussed in Customizing Your Linux iSCSI Settings (p. 376).
