3. In the menu that displays, from the Change/Show option, select the number of the adapter you are
configuring (Examples: ics0, ics1). The following is an example of the settings displayed when you
select an adapter number:
iSCSI Adapter
Description
Status
Location
iSCSI Initiator Name
Maximum number of Commands to Queue to Adapter
Maximum Transfer Size
Discovery Filename
Discovery Policy
Automatic Discovery Secrets Filename
Adapter IP Address
Adapter Subnet Mask
Adapter Gateway Address

Notes:
v Set the value for the Maximum number of Commands to Queue to Adapter to be greater than the
queue depth times the number of LUNs. For example, for 20 LUNs with a queue depth of 20, the
value should be greater than 400.
v To use flat file discovery, the Discovery Policy must be set to "file."
v Change the default file name /etc/iscsi/targetshw from targetshw to targetshwx where x is the adapter
instance number (Examples: ics0, ics1 ).
v The user may specify the iSCSI node name. If it is not specified, the adapter will use the default iSCSI
node name provided by the adapter. To display the iSCSI node name used by a particular adapter, use
the lscfg command to display the adapter VPD. For example, to display the iSCSI node name for ics0,
use lscfg -vl ics0. The iSCSI node name is in the Z1 field of the displayed VPD. The initiator's iSCSI
node name may be required to configure some iSCSI targets.
v If the rmdev command with the -d option is issued, then you must reenter the data in the specified
fields.
Updating the iSCSI targets flat file:
When autodiscovery is not used, the 1 Gigabit iSCSI TOE PCI-X adapter obtains the iSCSI target
descriptions from a flat file. The default file name is /etc/iscsi/targetshw. The information in this file
must accurately describe the target devices for this adapter.
For an explanation of this file format, see http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/
files/aixfiles/targets.htm.
Configuring the storage device:
To be visible to the adapter, storage devices must be correctly configured. Often the storage device must
be informed of the adapter iSCSI name, and the adapter must be informed of the storage device iSCSI
name. Additionally, either or both may need specific permissions to access the other side of the iSCSI
connection.
For instruction on configuring the storage device, refer to the support documentation provided by the
manufacturer of the storage device.
