How to check the status of the RAID controller

Run the following command to check the status of the DELL PERC H200 RAID controller:

sas2ircu LIST

An output like the following example displays:

How to check the status of the RAID

Run the following command to check the status of the hardware RAID on your Dell PERC H200:

sas2ircu-status

It displays information about the state of the RAID array:

-- Controller informations --
-- ID | Model
c0 | SAS2008
-- Arrays informations --
-- ID | Type | Size | Status
c0u0 | RAID1 | 1907G | Okay (OKY)
-- Disks informations
-- ID | Model | Status
c0u0p0 | ST32000444SS (9WM3NAR0) | Optimal (OPT)
c0u0p1 | ST32000444SS (9WM3MZL2) | Optimal (OPT)

How to optimize the performance of your hardware RAID

For maximum performance, you can activate the cache of your SATA disks. After creating a virtual disk, the cache of SATA disks is disabled by default. Restore maximum performance by re-enabling the cache using rescue mode.

Note

This step can be performed on Dedibox servers equipped with a DELL PERC H200 RAID controller and SATA hard disk drives.

  1. Boot your server into rescue mode using a 64-bit Ubuntu operating system.
  2. Log into the server using the provided SSH credentials and run the following commands to re-enable the disk cache:
    sudo su
    echo 'deb http://linux.dell.com/repo/community/deb/latest /' | sudo tee -a /etc/apt/sources.list.d/linux.dell.com.sources.list
    apt-get update && apt-get install -y --force-yes srvadmin-base
    service dataeng start
    /opt/dell/srvadmin/sbin/omconfig storage vdisk action=changepolicy controller=0 vdisk=0 diskcachepolicy=enabled
