Setting Drive Rebuild, Expand Priority, And Accelerator Ratio - HP 273914-B21 - Smart Array 6404/256 RAID Controller User Manual

5. When you have finished configuring the array, save the changes.
The following sections provide details of some typical procedures.

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 controller.
2. Select the controller settings:
If the controller is connected to at least one logical drive, CPQONLIN
continues in manual configuration mode. Use the arrow and Enter keys
to navigate around the screen and set up the logical drive. To get online
help at any time, press the F1 key.
NOTE: Newly created logical drives are invisible to the operating
system. To make the new logical drives available for data storage,
format them using the instructions given in the operating system
documentation.
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.
