2. Run the command script as shown in Example 18-2. The output is directed to a file called
south-africa.out for later verification. When this file has a size of zero every command in
the command file was executed without errors. However, since we included show
commands to provide some explanation what the commands are doing, the output file will
not be zero because this output goes into the output file.
Example 18-2 SMcli executes the script
amazon:~ # SMcli -n DS3300 -f south-africa.cmd -o south-africa.out -S
amazon:~ #

18.8 Configure the Microsoft iSCSI software initiator

The software initiator must be configured to access the created logical drives. This section will
describe two different variants of target discovery. On node Mara we will show target
discovery using iSNS, and on node Ora, target discovery will use the sendTargets command
for discovery. Once the target discovery is done, the remaining configuration tasks are the
same. If an iSNS server is available, it is recommended to use this - if no iSNS server is
available, the sendTargets method should be used.
We are describing both methods for completeness - normally you would use the same
method on all cluster nodes.

18.8.1 Configure target discovery using iSNS server

Follow these steps (on node Mara in our example), to configure target discovery using iSNS.
1. Open the iSCSI software initiator - Start → Program Files → Microsoft Software
Initiator → Microsoft Software Initiator. A window opens as in Figure 18-15 on
page 414. Click the Discovery tab.
