Foreign import
A virtual disk is considered foreign if it is not native to the adapter.
• A virtual disk is considered native to the adapter if:
– the virtual disk was created or imported on the adapter.
• A physical disk is considered native to the adapter if:
– There is no previous virtual disk metadata on the adapter and the physical disk are unconfigured.
– When the virtual disk corresponding to the physical disks is deleted
The system must be rebooted after performing foreign import.
To check for previous virtual disk metadata, see
presented to the operating system.
Upon migrating two foreign drives to a controller, you must do either of the following:
• Clear the controller configuration if using unconfigured drives —
• Import the virtual disk if using configured drives —
SMART info
SMART monitors certain physical aspects of the disk electronics to help detect predictable disk failures. Data on SMART-compliant physical
disks can be monitored to identify changes in values and determine whether the values are within the threshold limits. Any electrical failures
in the disk can cause degradation in the performance before failure.
A SMART failure is also referred to as a predicted failure. There are numerous factors that predict physical disk failures, such as a read error
rate, throughput performance, and changes in spin-up time. In addition, there are factors related to read/write surface failure, such as seek
error rate and excessive bad blocks.
NOTE: The BOSS-S1 CLI displays error messages with the status OK and NOT OK along with smart attributes.
