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 uncongured.
• All congured virtual disk on the physical disk are deleted
System needs to be rebooted after performing foreign import.
To check for previous virtual disk metadata, see Controller Information. Only a virtual disk or physical disk native to adapter will be
presented to the operating system.
Upon migrating two foreign drives to a controller, you must do either of the following:
• Clear the Controller Conguration if using uncongured drives — Clear Controller Conguration.
• Import the virtual disk if using congured drives — Virtual Disk Import.
SMART info
SMART monitors certain physical aspects of all motors, heads, and physical disk electronics to help detect predictable physical disk failures.
Data on SMART-compliant physical disks can be monitored to identify changes in values and determine whether the values are within
threshold limits. Many mechanical and electrical failures display some degradation in performance before failure.
A SMART failure is also referred to as predicted failure. There are numerous factors that are predicted physical disk failures, such as a
bearing failure, a broken read/write head, and changes in spin-up rate. In addition, there are factors related to read/write surface failure,
such as seek error rate and excessive bad sectors.
NOTE
: BOSS-S1 CLI displays error message with the status OK and NOT OK along with smart attributes.
