How to Recover Data from RAID0 and 5 Based on HP P822 Controller. Two RAID systems on one controller - Hetman Software
find out how to create two RAID systems based on one controller. How to create RAID level 0 and 5 on an HP controller with the help of Array Configuration Utility. You-ll also learn why people may need several arrays built on one controller, and how to recover data from a RAID system based on HP P822 controller.

The first step is to find the utility on the HPE official website and download it.
Run the utility and check the information about our controller. In order to address a specific controller to build a RAID system, you need to identify the slot to which it is connected. This can be done with the command below:
controller all show
This command addresses all controllers and shows their status. As a result, you-ll see the list of controllers and the slots where each of them belongs.
Now you need to find out what disks are connected to the controller. Here is the command to use:
controller slot=1 physicaldrive all show
The command addresses the controller in the first slot and displays all physical disks connected to it, as well as the drives united into a RAID system.
When you identify the disks that the future array will consist of, you can start building this RAID. Use the command -create-:
hpacucli controller slot=1 create type=ld drives=allunassigned raid=5 size=max
hpacucli controller slot=1 create type=ld drives=1:5,1:6,1:7 raid=5 size=max
This command contains the following attributes:
Controller slot - 1.
Device type to be created: -ld- which stands for logical disk.
The disks to be included into this RAID can be presented as a list of drives, or you can select all unassigned drives.
Another part of the command is the RAID level to be created.
Finally, you specify the size of the logical disk you want to create. You can either give it in megabytes or select all available capacity, by adding -max.-
To check if this command was successful, use another one to check:
hpacucli controller slot=1 show config
As a result, you-ll get the information about all arrays created on this controller in a specific slot.
