![]() ![]() Physicaldrive 1:1 (port 1:id 1, Parallel SCSI, 146.8 GB, OK) ![]() Physicaldrive 1:0 (port 1:id 0, Parallel SCSI, 146.8 GB, Rebuilding) Logicaldrive 2 (136.7 GB, RAID 1, Recovering, 21% complete) When you insert a new disk, it will automatically start mirroring and you can see the status of the hard disk mirror using the hpacucli command as shown below: hpacucliĪrray A (Parallel SCSI, Unused Space: 0 MB) If you have a spare disk you can easily replace it because it uses hot swappable hard disks. For example, if a hard drive fails, you will receive an alert from HPSIM. You will receive a mail from HPSIM for any hardware failures because you would have configured this during server build. How to Check Disk Mirroring Status on HP ProLiant Servers using hpacucli Tool Both disks are healthy, which is why it shows ‘OK’.Physical drives are sitting on Bay-1 and Bay-2.Two physical drives has added and each drive size is 146GB.Physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 146 GB, OK) Physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 146 GB, OK) Type "help" for a list of supported commands. HP Array Configuration Utility CLI 8.30-5.0 Use the ‘hpacucli’ (aka HP Array Configuration Utility) tool to check other configurations about HP Smart Array controllers such as list of hard disks, hard disk health, Raid level, disk bay location, etc. /dev/cciss/ c0d0p1 – Controller 0, disk 0, partition 1Ĭhecking Hardware RAID Configuration on HP ProLiant Servers using hpacucli Tool./dev/cciss/ c0d0 – Controller 0, disk 0, whole device.Max # commands on controller since init: 240 The below output clearly shows that 'RAID 1' is configured on the 'cciss0' array controller. You can identify the device name using the df command as shown below: df -h | grep cciss To view the configuration of each controller, use the following command. lspci | grep -i raidĠc:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)Ĭciss is a block driver for older HP Smart Array RAID controllers. The below output shows the raid controller is present on the system, which doesn’t mean that we have already configured RAID on the server. Use the lspci command to check if your system has physical RAID controller or not, in most cases physical servers use to have hardware raid controller. How to Check Hardware RAID Configuration on HP ProLiant Servers In this guide, we’ll show you how to check hardware RAID configured on HP ProLiant servers from Linux. It combines multiple physical hard disk drives into one or more logical drive to improve performance and reliability. RAID stands for Redundant Array of Inexpensive Disks. ![]() It means, it does not take any resources from the operating system to perform raid related tasks. The RAID controller manages and performs all RAID-related tasks independently of the OS. Hardware RAID is configured on the physical servers, which use a dedicated RAID controller to manage the raid configuration. ![]()
