Hardware Raid on pSeries RedHat

I'm not familiar with Redhat other than stumbling through an install on two partitions through the HMC on raid devices.

Now, we need to install additional disks and the customer wants it set up as hardware raid.

Is there a document that explains how this happens?

Re: Hardware Raid on pSeries RedHat

What type of storage are you using? The best and easiest way is to define the RAID arrays and provision LUNs from the storage device, such as a DS4300.

But if your storage is JBOD, then you have to make sure your adapters are RAID adapters. If not, you simply can't do it via hardware. That means software RAID which will degrade performance noticably.

Re: Hardware Raid on pSeries RedHat

Hi,

To configure RAID in Linux, please use ServerRAID CD to boot and go straight forward (make sure you connect all the disk drives to appropriate raid controller).

To configure RAID in AIX, with DS4000 series we can use StorageManager CD (FAStT) or if we use local disk drives to build RAID, we can use Raid Array Manager function in diag command
