Re: Question on Iscsi Behavior

[Ye, Ting]

Hi Karunakar,

In "Enabled" mode, only connected attempts will be recorded in iBFT while in "Enabled for MPIO", all configured attempts will be recorded in iBFT.
In "Enabled for MPIO" mode, the first configured attempt (according to attempt order displayed) is preferred. If the first attempt is valid it will not connect other attempts. While in "Enabled" mode, all configured attempts will be tried.

Thanks,
Ting Ye

Hello All,

Could you please help in clarifying below question on ISCSI behavior.

2 ISCSI Attempts are added with different configuration

Case 1:
Attempt 1------Enabled(ISCSI Mode)------IP4-----DHCP ---> In Valid Attempt (In Valid Target Details) Attempt 2------Enabled(ISCSI Mode)------IP4-----DHCP ---> Valid Attempt
Result:-
-> Initiator IP Assigned for Attempt1 and Attempt2(2 times DHCP process 
->done) ISCSI connection success with Attempt2 and same Details was 
->found in Shell

Case 2:
Attempt 1------Enabled for MPIO(ISCSI Mode)------IP4-----DHCP ---> In Valid Attempt (In Valid Target Details) Attempt 2------Enabled for MPIO(ISCSI Mode)------IP4-----DHCP ---> Valid Attempt
Result:-
-> Initiator IP Assigned for Attempt1 and Attempt2(2 times DHCP process 
->done) ISCSI connection success with Attempt2 and same Details was 
->found in Shell

Note: Same behavior seen with adding attempts for 2 different MAC addresses


1.        What is the difference between ISCSI Mode Enable & Enabled for MPIO ?
Because irrespective of ISCSI Mode, Attempt2 will be processed if Attempt1 is In Valid


Thanks,
karunakar
