I wanted to start utilizing an iSCSI storage system that we had for our ESX servers but didn’t want to have the iSCSI traffic using any of the existing NIC’s in these ESX servers. So the first step was to\u00a0put the NIC’s we previously added to the servers into a new VSwitch. Connection type for ISCSI will use vkernel.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

Once the VSwitch\u00a0is created take note of \u00a0use the name assigned. In this case vmk3<\/strong><\/p>\n

The default software iSCSI adapter listed under configuration -> storage adapters on the ESX host show up on my system as vmhba37.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

To view\u00a0which NIC’s, if any, have been assigned to the iSCSI software adapter\u00a0(vmhba37)you can run the following command:<\/p>\n

[acct@esxserver ~]# esxcli swiscsi nic list -d vmhba37 Errors: No nics found for this adapter.<\/strong><\/p>\n

In this instance there are no NIC’s assigned to vmhba37.\u00a0Since none are specified, by default the system will pick an existing one at random and use it.<\/p>\n

To assign specific NIC(s) to the iSCSI software adapter you can run the following command(s).<\/p>\n

<\/strong>[acct@esxserver ~]#esxcli swiscsi nic add -n vmk3 -d vmhba37<\/strong><\/p>\n

[acct@esxserver ~]#esxcli swiscsi nic list -d vmhba37 <\/strong>vmk3 \u00a0\u00a0\u00a0 pNic name: vmnic5 \u00a0\u00a0\u00a0 ipv4 address: 10.10.10.42\u00a0\u00a0\u00a0\u00a0 ipv4 net mask: 255.255.255.0 \u00a0\u00a0\u00a0 ipv6 addresses: \u00a0\u00a0\u00a0 mac address: g4:de:56:a4:3c:42\u00a0\u00a0\u00a0\u00a0 mtu: 1500 \u00a0\u00a0\u00a0 toe: false \u00a0\u00a0\u00a0 tso: true \u00a0\u00a0\u00a0 tcp checksum: false \u00a0\u00a0\u00a0 vlan: true \u00a0\u00a0\u00a0 vlanId: 0 \u00a0\u00a0\u00a0 ports reserved: 63488~65536 \u00a0\u00a0\u00a0 link connected: true \u00a0\u00a0\u00a0 ethernet speed: 1000 \u00a0\u00a0\u00a0 packets received: 5270264 \u00a0\u00a0\u00a0 packets sent: 26 \u00a0\u00a0\u00a0 NIC driver: igb \u00a0\u00a0\u00a0 driver version: 3.1.17 \u00a0\u00a0\u00a0 firmware version: 3.19-0<\/strong><\/p>\n

You can see by running the “list” command that after you’ve assigned the NIC to the iSCSI software adapter it now shows additional info, specifically network info for\u00a0the assigned NIC.<\/p>\n","protected":false},"excerpt":{"rendered":"
