vSphere managment network reconfiguration

[zvitins]

Hi all,

I have 5 VMware ESXi 4.1 hosts + vCenter.

Now I have plans to extend DC, but current subnet for managment and vmotion is too smal.

All current servers are using cSwitch0 for all (vmotion, managment etc)

I have instaled new EXS host, put in different subnet and want to add in HA cluster.

vSwitch0 - managment

vSwitch1 - only vmotion

I got error:

Host vth-01 has the following extra networks not used by other hosts for HA communication:192.168.21.194,. Consider using HA advanced option
das.allowNetwork to control network usage

Host vth-01 does not have the following networks used by other hosts for HA communication:192.168.17.244,. Consider using HA advanced option das.
allowNetwork to control network usage

If in HA advanced options I put "das.AllowVmotionNetworks  True" and "das.AllowNetworks0 Service Console"

I still got error:

Host vth-01 (new ESXi Host)  currently has no available networks for ha comunication. The following networks are currently used by HA: Managmetn Console

what should else I have to do, to put this host in HA cluster?

Thanks.

Hello,

now get different error error:

Host vt-02 (old ESXi Host)  currently has no available networks forHA comunication. The following networks are currently used by HA: Managment Console

I tried to reconfigure HA agents on old ESX hosts, but get same error on 3 of them.

If I remove all parameters from HA advanced options all HA agents on old hosts work fine

Thanks.

Hi

Have you set both parameters ?

das.allowNetwork Service Console
das.bypassNetCompatCheck True

if yes, post a printscreen of networking configuration from old and new esxi servers

Hi,

in HA advanced options I have 3 parameters:

"das.AllowVmotionNetworks  True"

"das.AllowNetworks0 Service Console"

"das.bypassNetCompatCheck True"

picture1 - new ESX host vSwitch0

picture2 - new ESX host vSwitch1

picture3 - old ESX host vSwitch0

All ESX hosts are in one VLAN, but in different subnets.

Thanks.

Host vt-02 (old ESXi Host)  currently has no available networks forHA comunication. The following networks are currently used by HA: Managment Console

hmm

you have ESXi so, I think insted of using Service Console (is in ESX) you should try with Management Network parameter (simply you don't have port group named Service Console in networking configuration)

das.allowNetwork  Management Network

P.S advance option is called das.allowNetwork not das.allowNetworks

"das.AllowNetwork0 Management Network"

"das.bypassNetCompatCheck True"

and all working fine.

Thanks,
