Recover point installation
Hi Guys,
I am stuck at recover point for VM installation, after installing the splitter on ESXi host.
I created software iSCSI adapter but not able to attach it to a VMKernel adapter,vmk adapters are not showing at Bind with VMKernel Network Adapter.
The environment is VMWare VSAN where I am using 2 NIC as standby, I checked VMWare KB article
and it says I cannot bind SCSI adapter if I have a vmnic as standby.
This kill my whole design for VSAN, or it means that I would have to use 2 more NIC to use for Recover point for VM.
Please help me if my understanding is correct.
Thanks
Kapil

Thanks a lot for the reply Fadliz, I am checking RP_VE on VSAN for POC.
In our production environment we generally have many uplinks all most of them are in Active/standby but no unused.
In that environment, do you suggest that I should have 2 more NIC card and they should be as active?
Thanks

Kapil,
You will have to edit the NIC teaming policy under the VMkernel ports to use 1 NIC as Active and the 2nd as Unused. This is a VMware requirement. Later this month will have an updated Guide that talks about one specific implementation where NIC teaming policies have to be modified.
Also since you are using VSAN, make sure you'r using RPVM 4.2.0.1.
Thanks

The VMkernel ports that you created to be used with the software iSCSI adapter need to have their NIC teaming policy edited (it sounds that you are using an existing vswitch with NIC teaming enabled). Edit the policy to use one interface as Activd and make the other 'unused'. Once you do that, the VMkernel port(s) will show up as available when binding ports to the software adapter.
The question on whether you should dedicate interfaces in production all depends on sizing and expected traffic. Those interfaces are used by the splitter to send writes to the vRPAs as well as by the vRPAs to access vmdks.
From config perspective make sure the VMkernel ports are using IP addresses reachable by the vRPAs iSCSI interfaces.

Yes you are right, I am using a distributed switch, and they are configured to as active passive and one NIC is carrying VSAN traffic and other one vMotion and they are acting as active-standby for each other.
so in this case, I do not have any free NICs to be used in a standard vswitch., does it mean I cannot use this product in this setup.
BR,

Even w/ your current vSwitch configuration, you should be able to modify only the VMkernel ports that you created to use one adapter.

Thanks a lot Fadliz, managed to pull through it.
Stuck at other item.
EMC has always frustrated me with documentation, they really need to learn how to write good document.
Even after acquiring VMWARE, they have not learned

Hi Kapil,
Glad to hear that it worked out.
Please make sure you’re using the latest version of the docs, posted on 2/3. We have added some topology diagrams and installation flowcharts.
