hello

Thanks for your answer.
I've checked the version of the DSS-Module: 1.15.DB00000000.2553
There are four NIC's in this server, where three of them are bonded while the fourth is standalone for mantanance.
As far as i can see, the MS iSCSI Initiator is configured to use MPIO

I will check dmesg, cable, switch and will post the result as soon as possible. I also will do an check disk on the W2k3-Servers

thanks

kind regards
