I am trying to connect Dell MD3200i iSCSI SAN from my 2 Dell R720 servers from Hardware iSCSI initiator (bios). Below is my configuration:
MD3200i HBA ConfigurationHBA1port0: 192.168.30.100port1: 192.168.31.100port2: 192.168.32.100port3: 192.168.33.100HBA2port0: 192.168.30.101port1: 192.168.31.101port2: 192.168.32.101port3: 192.168.33.101Dell R720 Configuration(Server 1)Nic0: 192.168.30.102 - Connected to HBA1 Port0Nic1: 192.168.30.103 - Connected to HBA2 Port0Nic2: 192.168.32.102 - Connected to HBA1 Port2Nic3: 192.168.32.103 - Connected to HBA2 Port2Dell R720 Configuration(Server 2)Nic0: 192.168.31.102 - Connected to HBA1 Port1Nic1: 192.168.31.103 - Connected to HBA2 Port1Nic2: 192.168.33.102 - Connected to HBA1 Port3Nic3: 192.168.33.103 - Connected to HBA2 Port3
The problem is servers shows it is connected to the SAN but I cannot find the iqn of my server in the san. I cannot connect to SAN from hardware iscsi but same configuration works well with vmware. Any idea would be of great help.
A server cannot/should not use the same subnet on 2 isolated networks (including direct-connected cables as this is considered a 2-port network). This is not an MD SAN or iSCSI limitation, but IP limitation.
So you'll need to stagger you connectivity.
Dell R720 Configuration(Server 1)
Nic0: 192.168.30.102 - Connected to HBA1 Port0
Nic1: 192.168.30.102 - Connected to HBA2 Port1
Nic2: 192.168.33.102 - Connected to HBA1 Port2
Nic3: 192.168.33.102 - Connected to HBA2 Port3
Dell R720 Configuration(Server 2)
Nic0: 192.168.30.103 - Connected to HBA1 Port0
Nic1: 192.168.31.103 - Connected to HBA2 Port1
Nic2: 192.168.32.103 - Connected to HBA1 Port2
Nic3: 192.168.33.103 - Connected to HBA2 Port3
Note: HBA stands for Host Bus Adapter, which is an (iSCSI, SAS or fiber) adapter that is put in a host (server). A better term to use for the iSCSI ports on the SAN is something like "Controller 0 iSCSI port 0". The NIC/iSCSI card in the server could/would be considered the HBA.

Are you trying to do a boot from san for your 2 servers or are you just wanting to connect the MD3200i via hardware instead of software iSCSI. Also what OS are you running on the 2 R720 & are the R720’s direct connected to the MD3200i or is it going through a switch.
Please let us know if you have any other questions.

I am trying to connect MD3200i via hardware instead of software iSCSI. I am using Vmware ESXi.5.1 on both of my servers. I have directly connected san with my servers without using a switch. Also, do I need crossover cable to directly connect to servers.
