There is information in the Inventory Assessment Workbook that you need in various phases of the transition. You should gather and record this information before you begin the transition so that you can reference it as needed throughout the process.

Steps

  1. Use the Inventory Collect Tool (ICT) to generate the Inventory Assessment Workbook.

  2. Open the Inventory Assessment Workbook.

  3. Go to the LUN tab.

  4. In the LUN name column, identify and record the name of the LUN to be transitioned.

  5. Go to the SAN Host LUNs tab.

  6. In the SCSI Device ID column, identify and record the SCSI device name.

  7. In the OS Device ID column, identify and record the DMMP device name for the LUN to be transitioned.

  8. In the Filesystems column, identify and record the file system configured on the DMMP device.

  9. In the UUID column, identify and record the UUID number for the LUN.

  10. In the Mount column, identify and record the directory on which the DMMP device is mounted.

  11. Go to the LVMs tab.

  12. In the Physical Volume Name column, identify and record the DMMP devices that are used by the logical volume.

  13. Go to the SAN Host LVMs tab.

  14. In the Volume Group Name column, identify and record the volume group.

  15. In the Logical Volume Path column, identify and record the logical volume.

  16. Go to the SAN Host Filesystems tab.

  17. In the Filesystem column, identify and record the file system configured on the logical volume.

  18. In the Mount column, identify and record the directory to which the logical volumes are mounted.

  19. Go to the GRUB Configuration tab.

  20. In the initrd column, identify and record the initrd image to be modified.

  21. Go to the SAN Host HBAs tab.

    You can also see the iSCSI SAN Interfaces tab to identify the iSCSI IQN number and IP addresses that are configured on 7-Mode controllers.

  22. In the Target IPs (iSCSI) column identify and record the iSCSI sessions for the 7-Mode controllers.
