FLI offline: Verifying migration results

Contributors

A verify job is optional, but recommended. It is a block-by-block comparison of the source and destination LUNs. Verify jobs take almost the same or slightly more time than migration time.

Steps

  1. Start the verify job to compare source and destination LUN. Monitor the verify progress.

    DataMig-cmode::*> lun import verify start -vserver datamig -path /vol/winvol/bootlun

DataMig-cmode::*> lun import verify start -vserver datamig -path /vol/winvol/fdrive

DataMig-cmode::*> lun import verify start -vserver datamig -path /vol/winvol/gdrive

  2. Monitor the verify job status.

    DataMig-cmode::*> lun import show -vserver datamig -fields vserver, foreign-disk, path, admin-state, operational-state, percent-complete, imported-blocks, total-blocks, , estimated-remaining-duration
vserver foreign-disk path               admin-state operational-state percent-complete imported-blocks total-blocks estimated-remaining-duration
------- ------------ ------------------ ----------- ----------------- ---------------- --------------- ------------ ----------------------------
datamig 83017542000E /vol/winvol/fdrive started     in_progress       57               -               4194304      00:01:19
datamig 83017542000F /vol/winvol/gdrive started     in_progress       40               -               6291456      00:02:44
datamig 830175420010 /vol/linuxvol/bootlun
                                        started     in_progress       8                -               41943040     00:20:29
3 entries were displayed.

  3. Confirm that verify jobs are completed.

    DataMig-cmode::*> lun import show -vserver datamig -fields vserver, foreign-disk, path, admin-state, operational-state, percent-complete, imported-blocks, total-blocks, , estimated-remaining-duration
vserver foreign-disk path               admin-state operational-state percent-complete imported-blocks total-blocks estimated-remaining-duration
------- ------------ ------------------ ----------- ----------------- ---------------- --------------- ------------ ----------------------------
datamig 83017542000E /vol/winvol/fdrive started     completed         100              -               4194304      -
datamig 83017542000F /vol/winvol/gdrive started     completed         100              -               6291456      -
datamig 830175420010 /vol/linuxvol/bootlun
                                        started     completed         100              -               41943040     -
3 entries were displayed.

  4. Stop the verify job after verify is completed.

    DataMig-cmode::*> lun import verify stop -vserver datamig -path /vol/esxvol/winrdmplun

  5. Delete the import relationship to remove the migration job.

    DataMig-cmode::*> lun import delete -vserver datamig -path /vol/winvol/bootlun

DataMig-cmode::*> lun import delete -vserver datamig -path /vol/winvol/fdrive

DataMig-cmode::*> lun import delete -vserver datamig -path /vol/winvol/gdrive

  6. Verify import jobs are deleted.

    DataMig-cmode::*> lun import show -vserver datamig
There are no entries matching your query.

  7. Mark the foreign LUN attribute to false.

    DataMig-cmode::*> storage disk modify { -serial-number 83017542001E }
-is-foreign false

DataMig-cmode::*> storage disk modify { -serial-number 83017542000E }
-is-foreign false

DataMig-cmode::*> storage disk modify { -serial-number 83017542000F }
-is-foreign false

  8. Verify the foreign LUNs are marked as false after import.

    DataMig-cmode::*> storage disk show -array-name HITACHI_DF600F_1 -fields disk, serial-number, container-type, owner,import-in-progress, is-foreign
disk     owner is-foreign container-type import-in-progress serial-number
-------- ----- ---------- -------------- ------------------ -------------
HIT-1.2  -     false      unassigned     false              83017542001E
HIT-1.3  -     false      unassigned     false              83017542000E
HIT-1.4  -     false      unassigned     false              83017542000F
3 entries were displayed.

  9. Bring the destination LUNs online using the lun online command.

    DataMig-cmode::*> lun online -vserver datamig -path /vol/winvol/bootlun

DataMig-cmode::*> lun online -vserver datamig -path /vol/winvol/fdrive

DataMig-cmode::*> lun online -vserver datamig -path /vol/winvol/gdrive

  10. Verify the LUNs are online.

    DataMig-cmode::*> lun show -vserver datamig
Vserver   Path                            State   Mapped   Type        Size
--------- ------------------------------- ------- -------- -------- --------
datamig   /vol/esxvol/bootlun             online  mapped   vmware       20GB
datamig   /vol/esxvol/linuxrdmvlun        online  mapped   linux         2GB
datamig   /vol/esxvol/solrdmplun          online  mapped   solaris       2GB
3 entries were displayed.
    Note

    Import logs are stored in cluster event log file.
