Customizing the chassis name
The Chassis Name field is available for a user-defined, customized name that
helps define the connection between the server HBA and the storage system
controller. This field prevents the user from relying entirely on the adapter ID of
the host controller for identification purposes.
Enabling chassis identification
The Identify Chassis field enables the user to set the Chassis Blink Status. When
enabled through the server HBA, CPQONLIN directs the storage system
controller to start flashing the hard drives LEDs in the storage system chassis.
When the setting is disabled, the hard drive LEDs stop flashing.
Setting drive rebuild, expand priority, and accelerator ratio
1. Go to the Main Configuration View screen.
2. Highlight the controller.
3. Select the Controller Settings option below Controller Options. The
Controller Settings screen appears.
Drive rebuild
Drive rebuild occurs after a physical drive fails and is replaced. Only logical
drives configured for fault tolerance (RAID 1, RAID 5, ADG) on the array with
the failed physical drive will rebuild.
Priority settings
To set the drive rebuild priority:
1. Highlight the MSA500 G2 controller.
2. Select the controller settings:
– If you choose low priority for drive rebuild, drive rebuilding occurs when
I/O to the drive is inactive.
– If you choose high priority, drive rebuilding occurs faster, at the expense
of normal I/O operations.
