The system drive to be expanded must be online and in Optimal state.
The capacity of each of the added disk drives must be greater than or equal to that of the smallest disk drive in the RAID
set.
Using the enlarge system drive option, the system drive specified is enlarged as well as having its data striped across a
larger number of physical disk drives. For this option, the system drive specified must be the only system drive on the
pack of disk drives being migrated.
Add capacity input parameters and execution parameters are kept in NVRAM and COD. The process is restarted
automatically by the firmware after a power failure.
In the event that this process must be terminated (for example, two disk drives fail and cannot be recovered), the
controller automatically aborts the migration process.
Expanding a Logical Drive, Background initialization, Initialize system drive, Automatic rebuild, and Consistency
check are mutually exclusive operations. Only one process can run at a time.
No configuration update commands issued from the host are allowed during this process.
Write-back is disabled during the process but resumes at the end of the operation.
Removing and replacing a controller, during migration can result in data loss. A hardware error, which renders the
controller unusable or the NVRAM unreadable, also results in data loss during migration.
CAUTION:
It is highly recommended that you backup all of your data and your current configuration before
making modifications. See 5.11 Backing Up a Controller Configuration on page 107.
To perform an Array Expansion, follow these steps:
To expand an array, the partner controller must be stopped. Click Controller -> Stop Partner Controller.
Note:
It may take a few minutes to stop the partner controller.
In the navigation area, select the array that you need to expand.
Click Array->Expand from the menu bar.
The Manual Storage Configuration: Expand Logical Drive window opens.
