It is recommended that the user establish multiple sessions to the XstreamCORE ET 8100T from each host. Also, the user should set
up one session per "Data Port" to each of the ports of the network cards. This ensures that if a link goes down a session can be
restarted.
Linux
Prerequisites
• Server with a 10GbE adapter running a supported Linux
kernel.
• XstreamCORE data ports configured and connected to the
same network as the 10GbE adapter.
Initiator Setup Instructions
If any command fails with permission denied, prefix
the command with sudo, and try again.
Install the iSCSI Initiator Utilities
For systems using apt package management, enter the
following command: apt install open-iscsi
For systems using yum package management, enter the
following command: yum install iscsi-initiator-utils
To determine which package management software
is used by your Linux distribution, use the following command:
which yum
If the output is similar to /bin/yum, this distribution uses yum,
otherwise it uses apt.
Configure the Data Ports
For iSCSI applications, the in-box driver should be used to
connect the 8100 to the host.
Ports may be auto-configured if connected to a network
with DHCP. Otherwise, they will need to be assigned an
IP address using the ipconfig command.
If Ethernet ports are direct-connected to the
XstreamCORE without the use of a switch and both data ports
are used, the XstreamCORE data ports must not be on the same
subnet.
Test the network connection using the ping command.
Note the IP address of the XstreamCORE data port and
then on the initiator, enter the following command:
ping ipaddress
ipaddress is the address of the XstreamCORE data
port.
Sample output:
5 Initiator Configuration
PING 172.16.1.20 (172.16.1.20) 56(84) bytes of data.
64 bytes from 172.16.1.20: icmp_seq=1 ttl=64 time=0.144 ms
64 bytes from 172.16.1.20: icmp_seq=2 ttl=64 time=0.111 ms
64 bytes from 172.16.1.20: icmp_seq=3 ttl=64 time=0.116 ms
LTFS Setup for Tape Devices
If using tape devices in a LTFS setup, install Linear Tape File
System (LTFS) software provided by the tape device
manufacturer.
Discover XstreamCORE Targets
If one-way or two-way CHAP authentication has been
configured on the XstreamCORE for the discovery session,
open /etc/iscsi/iscsid.conf in a text editor and add or modify
the following lines:
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = username
discovery.sendtargets.auth.password = password
username and password must match the CHAP In
Account Name and CHAP In Secret configured on the
XstreamCORE for discovery. Both username and password are
case-sensitive.
If two-way CHAP authentication has been configured on the
XstreamCORE for discovery, also add or modify the following
lines in /etc/iscsi/iscsid.conf:
discovery.sendtargets.auth.username_in = username_in
discovery.sendtargets.auth.password_in = password_in
username_in and password_in must match the CHAP
Out Account Name and CHAP Out Secret configured on the
XstreamCORE for discovery. Both username_in and
password_in are case-sensitive.
You must log out of any current sessions and re-
perform discovery for the CHAP settings to take effect.
