At the release of this document, the importing of virtual drives from one SAS–2 REM to another is only supported if you are replacing a failed REM with an identical REM. For example, if you have a Sun Storage 6Gb SAS REM HBA (SGX-SAS6–REM-Z) connected to the Sun Blade Storage Module M2 and the REM fails (but the drives are good), you can import the existing virtual drives to a replacement Sun Storage 6Gb SAS REM HBA (SGX-SAS6–REM-Z).
Caution - Importing virtual drives between different technology REMs, such as importing IR virtual drives created using an LSI Fustion-MPT IR REM (SGX-SAS6–REM-Z) to an LSI MegaRAID REM (SGX-SAS6–R-REM-Z). is not supported. This is because a mismatch in metadata size can cause an import operation to fail and data to be lost. To migrate virtual disk data from one type of REM to another, first do a full backup. Next, attach the drives to the new REM. Then, clear the existing virtual drive configuration and create a new virtual drive using the new REM. Once that is done, the data can be restored from backup to the new virtual drive.
