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.

Edit (or add) the following entries to the
/etc/iscsi.conf
file:
HeaderDigest=never
DataDigest=never
LoginTimeout=15
IdleTimeout=15
PingTimeout=5
ConnFailTimeout=144
AbortTimeout=10
ResetTimeout=30
Continuous=no
InitialR2T=no
ImmediateData=yes
MaxRecvDataSegmentLength=65536
