HP NetRAID 1 Controller - Manual (Page 19)

PFS is enabled/disabled through either the NetRAID Express Tools or NetRAID Config utilities.
The default setting is disabled. Since there is only a performance penalty during the reconstruction
operation itself, it is recommended to enable the feature unless there are some rigid time constraints
on reconstruction activities.
I. Autorebuild Feature
The Autorebuild feature detects the replacement of a failed disk drive and automatically rebuilds
onto it the data that was on the failed disk. For Autorebuild to occur, all of the following conditions
must be satisfied:
•
The HP NetRAID adapter BIOS firmware is version A.02.00 or later.
•
Autorebuild was enabled in HP NetRAID Express Tools for the adapter controlling the failed
drive.
•
The failed drive was replaced with a good drive in the SAME physical slot as the failed drive.
•
The replacement drive capacity is at least as large as the failed drive capacity.
To enable the Autorebuild feature in HP NetRAID Express Tools, do the following:
1. Restart the NetServer.
2. When the following prompt appears, immediately press <Ctrl> <m> to start HP NetRAID
Express Tools.
Option: Experienced users may press <Ctrl> <M> for HP NetRAID

3. When the system stops scanning, HP NetRAID Express Tools immediately starts and
displays the Management menu. Choose the Objects option from it.
4. From the Objects menu, choose Adapter. If more than one HP NetRAID or HP NetRAID-1
adapter is installed in the NetServer, the Adapter Selection box appears; select the desired
adapter.
5. The Adapter menu lists Auto Rebuild in its Disabled default state. Choose Auto Rebuild, and
then enable it.
6. If Autorebuild must be enabled on another adapter, press ESC to back up to the Objects
menu. Then repeat Steps 5 and 6 for that adapter.
7. When all adapters have Autorebuild enabled, press ESC repeatedly to back up to the
Management menu.
8. To exit HP NetRAID Express Tools, press ESC at the Management menu display. Choose
Yes at the prompt. You must then reboot the NetServer.
