BIG BUG in ESXi 5 patch2!! - Software iscsi - network unreachable - again - 20 minut boot

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!!!!!
