Known Issue & Workaround for NetApp iSCSI devices on SLES 10
Sometimes the NICs are not ready when iSCSI driver starts up. As a result the targets do not get logged in automatically. The work around is to add 1 minute wait time in the network startup script '/etc/init.d/network'.

Solaris 10 SPARC, and Solaris 10 X64 iSCSI initiator setup.
Note: Storage Foundation 5.0MP3 does not support iSCSI storage devices OS prior to Solaris 10 Update 4.
Note: Make sure the NICs to be used for iSCSI storage connection have IPs associated. The NICs should be able to ping the iSCSI targets IPs on the iSCSI storage. Also, the IPs need to be configured to make them available at boot time.
1. Install iSCSI software packages "SUNWiscsir" and "SUNWiscsiu" on the system if they are not installed already.
SUNWiscsir - iSCSI Devuce Driver
SUNWiscsiu - iSCSI Management Utilities
2. Check the system has met the minimum iSCSI patch requirement: 119090-30 (SPARC), 119091-31 (X64)
3. Issue the following command to configure the static discovery of iSCSI storage LUNs.
iscsiadm add static-config <target-name,target-address[:port-number][,tpgt]>
Note: the "tpgt" value may be required by certain iSCSI storage.
4. Issue the following command to enable the iSCSI static target discovery method.
iscsiadm modify discovery --static enable
5. Issue the following command to verify the iSCSI static target discovery method is enabled.
iscsiadm list discovery
6. Issue the following command to configure the iSCSI devices to the system.
devfsadm -i iscsi
