6224 dont work stack with vmware 5.1

i have 2 switches 6224 with stack and config its ok.

dell#show switch

    Management Standby   Preconfig     Plugged-in    Switch        Code  
SW  Status     Status    Model ID      Model ID      Status        Version
--- ---------- --------- ------------- ------------- ------------- -----------
1   Mgmt Sw              PCT6224       PCT6224       OK            3.3.3.3    
2   Stack Mbr  Oper Stby PCT6224       PCT6224       OK            3.3.3.3


but, i have same problem in my enviroment VMWare 5.1 with HA

example:

i have 3 server with 4 ports at each server

Server 1  > 2 ports for iSCSI and 2 ports for traffic of networks
Server 2  > 2 ports for iSCSI and 2 ports for traffic of networks
Server 3  > 2 ports for iSCSI and 2 ports for traffic of networks

Traffic Networks

Server 1 > 1 port in port 1 switch 1,  port 2 in port 1 in swtich 2
Server 2 > 1 port in port 2 switch 1,  port 2 in port 2 in swtich 2
Server 3 > 1 port in port 3 switch 1,  port 2 in port 3 in swtich 2

The problem, if i disconnect all ports in switch 2 of traffic networks, the enviroment works ok, but when i connect cable in switch 2
the enviroment crash and back work just when i disconnect the cable of switch 2.
In my VMWare Distributed Switch i have configure 2 ports with route base on ip hash.

i would like have in my enviroment the switchs in stack work together with vmware HA in nics of servers.

sameone have sugestion of this problem for vmware works ok with dell 6224 stacked

    Hi,

    Can you update the switch firmware to the latest version? There was a fix for some failover issues. http://www.dell.com/support/drivers/us/en/04/DriverDetails/Product/powerconnect-6224?driverId=77XG3&osCode=NAA&fileId=3288111910&languageCode=en&categoryId=NI

     

    Are the ports in a static or LACP lag?

    Are both units showing that they are unit one in the stack? Or does switch one work correctly and you only get an error on switch 2, if they are stacked all commands are run through the master. If you run show stack port what does it show?

    Does show switch 2 from the switch 1 cli show the 2nd switch?

    yes, each port of servers-esxi have lag configuration on each switch, but the traffic bettwen switch dont happen, the second switch dont work active-active with master, and i need config each port, jumbo frames in each switch, i cant config just one and replicate for other automatically, is this correct ??

    That looks like the stack is operating correctly. Is each server in its own lag with one more on each of the switches?

    Stacking makes the two switches act like a single switch, so if you need to configure ports on switch 2, it is done from the switch 1 cli, as it is the master,

    ok, but the switch 1 i had her work in my enviroment, i add the 2 switch after. and for example, if i disconect the cable 1 port 1 of  switch 1, the enviroment
    dont can stop, because the switch 2 and stack have work with this port and this not happen, i lost connection with this server. you can understand me ??

    i need that 2 switch stay with HA, work active-active.
