Setting Up Your iSCSI Storage Array

SESSION STATUS : ESTABLISHED AT Wed May 9 18:20:28 CDT 2007

SESSION ID : ISID 00023d000002 TSIH 4

*******************************************************************************

Viewing the status of your iSCSI connections

In MD Storage Manager, clicking the

iSCSI

tab and then

Configure iSCSI Host Ports

will show the

status of each iSCSI port you attempted to connect and the configuration state of all IP addresses. If
either displays

Disconnected

Unconfigured

, respectively, check the following and repeat the iSCSI

configuration steps:

•

Are all cables securely attached to each port on the host server and storage array?

•

Is TCP/IP correctly configured on all target host ports?

•

Is CHAP set up correctly on both the host server and the storage array?

To review optimal network setup and configuration settings, see

Guidelines for Configuring Your Network

for iSCSI
