Setting Up Your iSCSI Storage Array 41
If you are using Linux Server
Configuration of the iSCSI initiator for Red Hat
®
Enterprise Linux
®
version 4 and SUSE
®
Linux
Enterprise Server 9 distributions is performed by modifying the /etc/iscsi.conf file, which is installed by
default when you install MD Storage Manager. You can edit the file directly, or replace the default file
with a sample file included on the MD3000i Resource CD.
To use the sample file included on the CD:
1
Save the default
/etc/iscsi.conf
file by naming it to another name of your choice.
2
Copy the appropriate sample file from
/linux/etc
on the CD to
/etc/iscsi.conf
.
3
Rename the sample file to
iscsi.conf
.
4
Edit the
iscsi.conf
file and replace the IP address entries shown for
DiscoveryAddress=
with the
IP addresses assigned to the iSCSI ports on your storage array:
For example, if your MD3000i has two iSCSI controllers (four iSCSI ports), you will need to add four
IP addresses:
DiscoveryAddress=
<your_storage_array_IP_address>
DiscoveryAddress=
<your_storage_array_IP_address>
DiscoveryAddress=
<your_storage_array_IP_address>
DiscoveryAddress=
<your_storage_array_IP_address>
If you elect not to use the sample file on the CD, edit the existing default
/etc/iscsi.conf
file as shown
in the previous example.
