This appendix provides guidelines for migrating a container's
RAID level, expanding its size, or both. The configurations presented in
this appendix are typical; other configurations are possible.
Choosing Disks for Use in a Container
When using either the Container Reconfiguration Wizard or the Container Creation Wizard dialog boxes, the general guidelines in Table can be applied to the selection of disks in the wizards's Disks list for specifying the destination container:
Table 1. Guidelines for Selecting Disks
| If the disk is... |
Used in Destination... |
In Dest column contains... |
| Not selected |
Never |
|
| Selected |
Only if |
X |
| Selected and forced |
Always |
X |
The term destination container applies to both of these dialog boxes. In the Container Creation Wizard, the container being created is referred to as the destination container. In the Container Reconfiguration Wizard, the destination container is the end result of the container's reconfiguration process.
The term source container applies only to the Container Reconfiguration Wizard. The source container is the container being reconfigured.
See Reconfiguring a Container for more information on container reconfiguration.
Note:
To be eligible for reconfiguration (either as a source or destination
container), a container can have no more than 32 physical disks.
