How to identify XC Series volume group volumes in Linux guest

How to identify XC Series volume group volumes in Linux guest

  • ABS exposes the Nutanix DSF through the iSCSI protocol directly into the virtualized guests or physical systems. On the virtualized guests or physical systems, iSCSI services would be required to connect to ABS.

    Perform the following steps:

    1. Connect to one of the CVMs.
    1. Invoke the ncli interface.
    2. Issue the volume-group list command. A list of volume groups and the volumes within each volume group would be shown.
    3. Look for the Disks attribute in the output. All the virtual disks and their attributes including the VM Disk UUID would be listed.

    1. On Linux guest (Red Hat/Oracle Linux 6 or 7), extract the UUID with scsi_id commands:

    [root@oracle-node10 ~]# ls -1 /dev/sd?|while read device; do echo -n $device :; /lib/udev/scsi_id --page=0x83 --whitelisted --device=$device; done

    1. Match up results from steps 3 and 4 to show the vmdk and Linux device file relationship.
