I got your point but my question(s) are 1) I agree that if I add two attempts for the same NIC, there will be a war= ning popup. But my question is whether the second attempt also be tried for= connection if first attempt fails to connect? 2) Is it valid to add two attempts where both are 'Enable for MPIO' for the= same NIC? I'm not clear about IPv6, you mean to say we need to configure an IPv6 addr= ess apart from adding the Attempt?

For 2), Enabled for MPIO means you have enabled multi path I/O in iSCSI for= supporting failover. For 3 and 4), iSCSI does not allow configuring one new IPv6 address using i= SCSI menu so Attempt #1 does not show initiator address. Instead, iSCSI driver will let IPv6 driver to perform source address select= ion according to the configured iSCSI target IP address. You need assign IP= v6 source address using ifconfig6 or autoconfiguration before using iSCSI o= n IPv6 stack.

Please help me out. 1. If I have added two attempts and are enabled for the same MAC, if = the first attempt fails to connect, will the second attempt be tried? 2. If answer to the above is YES, then what's the difference between = ISCSI Modes 'Enabled' and 'Enable for MPIO'? 3. In our observation, we've found that the behavior is not same when= two attempts are added for IPv4 and IPv6. 4. Are there any standard set of test procedures for ISCSI behavior? The following is the conflict Case 1: Attempt#1------Enabled for MPIO------IPv6-----DHCP Attempt#2------Enabled f= or MPIO------IPv6-----DHCP Actual behavior: Attempt#2 doesn't show any initiator IPv6 address. Case 2: Attempt 1------Enabled for MPIO------IPv4-----DHCP Attempt 2------Enabled f= or MPIO------IPv4-----DHCP Actual behavior: Attempt#2 shows Initiator IPv4 address. Please provide your suggestions. Thank you Naveen _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
