Automatic Rebuild Management (ARM) controls whether the controller
will automatically begin a rebuild operation on an existing hot spare drive
when an active drive fails. If ARM is disabled, the controller will not
automatically initiate a rebuild operation. However, the rebuild operation
can be initiated manually through the VT100 emulator or AdminiStor PC
Utilities – RAIDfx program. If ARM is enabled, the controller will
automatically initiate a rebuild operation if an appropriately sized hot
spare drive is available at the time of a drive failure.
Operational Fault Management (OFM) controls whether the controller
performs any environmental monitoring (AEMI or SAF-TE). OFM must
be enabled for the controller to detect power supply, fan, and temperature
failures. OFM must also be enabled for drive push/pulls to be detected
and for ARM to work.
The default and recommended setting should be for both ARM and OFM
to be enabled.
The "Disconnect on First Command" option should be set to Disabled.
With this bit enabled the controller will not grant disconnect privileges
on the first command issued to back-end devices after a bus reset. This
setting should be disabled.
