Migrating a volume manually
A volume can be migrated manually through the Manual Plan window.
Prerequisites
•
The Auto Migration function is disabled. See “Stopping the Auto Migration function” (page 28) .
•
The user has permission to access the source and target volume
•
The volumes meet all requirements as source and target volume candidates
•
You can also migrate a Thin Provisioning or Thin Provisioning Z virtual volume or an external
volume manually. However, you cannot examine the estimated usage rate after migration
because the usage rate of an external volume cannot be collected.
•
OPEN-V volumes other than the Thin Provisioning or Thin Provisioning Z virtual volumes might
not be displayed as target volumes.
•
The system disk cannot be migrated.
Procedure 1 To migrate a volume manually:
1. Click Actions
→Other Function→Auto LUN.
2. Click to change to Modify mode.
3. In the Monitoring Term section, specify the starting time and ending time to collect performance
and usage statistics, and click Apply.
In a later step, a graph will be created based on this specified period.
NOTE: Do not include the period when an error occurred. Resource usage can become
unbalanced when the storage system experiences an error.
4. In the Auto LUN window, click Plan. A different window appears and the Manual Migration
window is displayed.
5. Click the Manual Plan tab to display the “Manual Migration window” (page 50) .
6. In the navigation tree, click the parity group that contains the volume you want to migrate. To
display the usage rate of the parity groups, click Display usage rate.
The volumes contained in the selected parity group load in the “LDEVs list” (page 53) .
7. In the “LDEVs list” (page 53) , select the volume you want to migrate and then click Target.
The “Target (Reserved) LDEV list” (page 53) displays the reserved volumes that can be used
as a target volume.
8. In the “Target (Reserved) LDEV list” (page 53) , select the target volume.
