  • Hi Karthik,

    How are the disks presented to VMs?

    If iSCSI, follow the link that Sandeep posted.

    If through VMware, I suggest you consult VMware technical support for help.

  • Its not iSCSI volumes. it's SCSI virual disk. Disks presented are dedicated LUN(i.e naa id) through mapping to VM server.

    Its dell article not matching our environment that scenario is ISCSI volumes

  • Hi Karthik,

    The procedures in the link not only apply to Dell devices. You could try on your devices.

    Did you mean you connect the iSCSI targets on host or VM?

  • Hi Leo,

    Thanks for your reply.

    All data disks presented dedicated LUN storage to a VM (scsi base not iscsi) will go offline after reboot.

    SCSI targets on host/VM

    NOTE: SCSI and ISCSI are different bus.

  • Hi Karthik,

    >>NOTE: SCSI and ISCSI are different bus.

    I know.

    I'm afraid I don't have the device to reproduce the issue to analyze. And considering the disks are presented through VMWare, I would suggest you contact VMWare support for help:
