How To Set Up The HP ProLiant RAID Rebuild Priority

In this article, I’ll show you how you can adjust HP ProLiant RAID rebuild priority. This will set the level of precedence you have assigned to a RAID array rebuild as compared to routine I/O tasks. If you set the priority to low, the rebuild will occur only when the controller is not busy with normal I/O operations. As a result, you’ll show minimum effect on routine I/O tasks.

But it is important to note here that any array rebuilt using a low priority setting can actually create a possibility of compromising default tolerance level at the time of rebuild. This can lead to a failure which requires professional HP ProLiant recovery.

However, if you set the rebuild priority level to medium, that rebuild will be done using 50% of the resources, leaving of course the remaining fifty percent, which will be allocated to normal I/O operations. If you apply a priority level setting, the rebuild will take place at the expense of typical I/O jobs. This setting has negative impact on overall performance but it ensures more efficient data protection. Therefore, we would suggest the high priority setting for any HP ProLiant RAID rebuild.

To apply your desired HP ProLiant RAID rebuild priority level setting, highlight the controller in the logical configuration view panel and hit Enter. Now highlight the option for Controller Settings and hit Enter. In the controller settings panel, highlight the rebuild priority setting you want to apply and press Enter. You are done; your desired setting has been applied.
