          Hi.

          From post is not clear: Is problem LDOM  guest or control?

          1. Check what device was configured for boot:  

                     printenv boot-device

                     printenv diag-device

                     printenv diag-switch?

           

          2. Check what disks available for LDOM:

                      probe-scsi-all

           

          3.  In case it guest   LDOM, check from configuration from Control LDOM

                     ldm list-bindings -e <LDOM_NAME>

           

          Regards,

              Nik

            Hello Team,

             

            Make sure back-end disk device is visible and showing up in the format output on the control domain.

             

            Check these outputs.

             

            ldm ls-services

            echo | format | grep -i c0t*d*

             

            Thanks

              As you try to boot from a 'disk0', you might check that as well.

              Here is some output from a logical domain with four disks attached. disk0 and disk1 form a mirrored rpool.

              {0} ok printenv boot-device

              boot-device =           /virtual-devices@100/channel-devices@200/disk@0:a /virtual-devices@100/channel-devices@200/disk@1:a disk net

              {0} ok devalias

              vdisks-2                 /virtual-devices@100/channel-devices@200/disk@3

              vdiskv-2                 /virtual-devices@100/channel-devices@200/disk@2

              vdisks-1                 /virtual-devices@100/channel-devices@200/disk@1

              vdiskv-1                 /virtual-devices@100/channel-devices@200/disk@0

              vnet0                    /virtual-devices@100/channel-devices@200/network@0

              net                      /virtual-devices@100/channel-devices@200/network@0

              disk                     /virtual-devices@100/channel-devices@200/disk@0

              virtual-console          /virtual-devices/console@1

              name                     aliases

               

              If disk0 is not defined, you might end up providing arguments to some boot target rather than selecting a boot device:

               

              {0} ok boot disk7

              Boot device: /virtual-devices@100/channel-devices@200/disk@0:a  File and args: disk7

              \

              Can't open disk7
