    Question ESX 4.1 loses iSCSI connection after reboot

    Hi,
    I'm running ESX 4.1 and planning to move the iSCSI storage from a single Windows Storage Server to two Open-E DSS V6 16TB Storage System which should run than Failover.
    Right now I have the strange problem, that after a ESX reboot for example the connection to the open-e iSCSI LUN can't be restored nor will any rebooted ESX find any LUN from the Open-E System.
    Quite disappointing.
    Only Solution is to reset the iSCSI Connections manually with the Web GUI of the Open-E System.
    This couldn't be a solution for an HA setup.

    How to fix this?

    be sure to assign static paths to the targets for the HBA, only pointing to the virtual IP(s).

    Hi that's all done.
    After I changed from File IO to Block IO this problem only appears with with Volumes greater than 1TB.
    I also get a huge amount of cmnd_abord 1143 errors.
    What could be the reason?


    Thx

    Those steps I've already tried...
    Another strange behavior is that an ESX Host crashed today due to my failure, and this host was creating a VM at an iSCSI target of the Open-E DSS V6. This target was totally lost - ESX will only find it with 0,00B size now.
    So what is the advice to create a stable and good running Open-E DSS V6 iSCSI Failover Cluster for VmWare ESX 4.1 ?

    Thanks

    You might want to check out VMware site about missing LUNs from the ESX side and how to get it back.
