Hi All
I'm use now ESXi 5 patch2 (iscsi patch) but still have problem with software iscsi.
Software iscsi not works correctly, if You have controllers in Storage A/A configured in 2 different subnets and differents vlan.
Then YOU HAVE PROBLEM!
And You Have configured 2 or more vmkernels on differents subnets. Then Software iscsi try connect from all vmkernels (from different subnets) to all Storage targets. I this moment is all problem start.
For Example:
If you have vmkernel:
vmk1 10.1.1.10/21
vmk2 10.2.1.10/21
2 different subnets in 2 different vlan
Storage with Active/Active
controller1 10.1.1.1/21
controller2 10.2.1.1/21
2 different subnets and different Vlan.
Software ISCSI try connect from vmk1 to controller 1 and controller2 (controller2 is in different subnets - network unreachable You can see in log) and software shouldn't connect from vmk1 to controller2. Becouse this is different subnet on different VLAN - Software iscsi not look on this.
For vmk2 is exactly the same.
Software iscsi try connect from vmk2 to controller 1 and 2 (controller 1 is not available for vmk2 - becouse this is different subnet on separated VLAN)
Then boot ESXi process using iscsi software take more time to connect wrong controller!!!!! 20 minuts boot process for some ESXi configuration!!!!
Software ISCSI should look on mask nad vlan settings on vSwitch and connet only to available subnet mask network vmk1=controller1 and vmk2=controller2
In ESXi is only one iscsi Software adapter - adding 2 will be resolv problem - but add secound software iscsi adapter is not possible!!!!!
Staff of VMware should resolv this problem and look how user configure storage network for redundancy.
BUG BUG BUG BUG BUG in ESXi Software ISCSI!!!!!
