H.6 Post-migration Cleanup of Source Workloads

Source workloads might occasionally need a post-migration cleanup. For example, you might need to clean up a source workload of all PlateSpin software components after an unsuccessful migration.

H.6.1 Cleaning Up Windows Workloads

The following are instructions for cleaning up Windows workloads by component and use case.

Component

Use Case

Removal Instructions

File-based Transfer Component

All Migrations

At root level for each volume migrated, remove all files named PlateSpinCatalog*.dat

Workload discovery software

All migrations

  1. In the Servers view, undiscover the source (right-click, then select Undiscover).

  2. In the source workload’s Windows directory:

    • Remove all files named machinediscovery*.

    • Remove the subdirectory named platespin.

Controller software

All migrations

  1. In the Servers view, undiscover the source (right-click, then select Undiscover).

  2. Open a command prompt and change the current directory to:

    • \Program Files\platespin* (32-bit systems)

    • \Program Files (x86)\platespin (64-bit systems)

  3. Run the following command:

    ofxcontroller.exe /uninstall

  4. Remove the platespin* directory

H.6.2 Cleaning Up Linux Workloads

The following are instructions for cleaning up Linux workloads by component and use case.

Controller software

Offline migrations

In the source workload’s file system, under /boot, remove the ofx directory with its contents.

All live migrations

  • Kill these processes:

    • pkill -9 ofxcontrollerd

    • pkill -9 ofxjobexec

  • remove the OFX controller rpm package:

    rpm -e ofxcontrollerd

  • In the source workload’s file system, remove the /usr/lib/ofx directory with its contents.

Block-level data transfer software

All block-level migrations

  1. Check if the driver is active:

    lsmod | grep blkwatch

    If the driver is still loaded in memory, the result should contain a line, similar to the following:

    blkwatch_7616  70924  0

  2. (Conditional) If the driver is still loaded, remove it from memory:

    rmmod blkwatch_7616

  3. Remove the driver from the boot sequence:

    blkconfig -u

  4. Remove the driver files by deleting the following directory with its contents:

    /lib/modules/[Kernel_Version]/Platespin

  5. Delete the following file:

    /etc/blkwatch.conf

LVM snapshots

Block-level migrations using LVM snapshots

  1. In the Jobs view, generate a Job Report for the failed job, then note the name of the snapshot.

  2. Remove the snapshot device by using the following command:

    lvremove snapshot_name
