1-8 Volumes Used for Migration
Migration source and target volumes must satisfy the following conditions in a migration using Tiered Storage
Manager:
• The emulation types of the migration source volumes and migration target volumes match.
• The sizes of the migration source and migration target volumes match.
The emulation types of the migration source volumes and the migration target volumes are not OPEN-V,
but the volumes are both CVS or both normal.
You can check the emulation type and size of a volume in the Volume Detailed Information – Device Number
popup window. For details on this window, see the GUI Help.
• Volumes that cannot be migrated
For volumes that cannot be migrated, you can check the status from the Volume Detailed Information -
Device Number pop-up window - Can Migrate or Volume Status.
Can Migrate
When Yes is specified for Can Migrate, you can perform migration using the volume as a source
volume.
When No is specified, you cannot perform migration using the volume as a source volume. An error
occurs when you click the Migration button.
Volume Status
When Unused is specified for Volume Status, it is available as a source target.
When Used is specified, the volume will not be displayed as a candidate for the migration target
volume.
When No is specified for Can Migrate, or Used is specified for Volume Status, the reasons are displayed in
Reasons that a volume cannot become source/target volume in the Volume Detailed Information - Device
Number pop-up window. For details on the character strings to be displayed and their descriptions, see Table
1.5 Character Strings Representing Reasons a Volume Cannot Be a Migration Source or Target, and a
Description of those Character Strings.
• Volumes that cannot be checked for migration suitability
The following volumes cannot be checked for suitability by using Can Migrate or Volume Status. An error
occurs when executing a migration task with these volumes selected as a source volume. Also, an error
occurs when creating a migration task that has these volumes selected as migration target volumes.
• A volume that makes up a Cross-system Copy pair
• A volume that is the target of XRC (Extended Remote Copy, which is the IBM remote copy function)
• A volume that is the target of Concurrent copy
• A volume that cannot be accessed because it has a blocked status or is being formatted
An error occurs when executing a migration task using the following volumes together:
• For a migration source volume: volume made up of a TrueCopy pair
• For a migration target volume: externally connected volumes
• Information displayed as reasons that a volume cannot be a migration source or target
When migration suitability checks can be performed from Tiered Storage Manager, if volumes are
determined to be unsuitable as a migration source or target, the reasons are displayed in Reasons that a
volume cannot become source/target volume in the Volume Detailed Information - Device Number pop-up
window.
The following table shows the character strings representing the reasons that a volume cannot be a
migration source or target.
Volumes that can be checked by Tiered Storage Manager, and for which a migration task or data deletion task
is being executed, are not displayed in Reasons that a volume cannot become source/target volume. Such
volumes cannot be used as either migration source volumes or migration target volumes.
