The SAN Volume Controller supports
Logical Unit Size Expansion (LUSE) with certain restrictions.
The following restrictions apply:
- Before LUSE can be performed on an LU, the LU must be unmounted
from a host and have no available paths. The LUSE function destroys
all data that exists on the LU, except for LUs on a Windows® operating system.
- LUSE must not be performed on any disk that is managed by the SAN Volume Controller.
- If data exists on a disk and you want to use image mode to import
the data, do not use LUSE on the disk before you import the data.
