How to change the RAID level from RAID 0 to RAID 1+0 in HP Blade server?

Please find the steps to change the RAID level from RAID 0 to RAID 1+0. Please do in one low priority server in site first and then proceed to do in other servers.

1.    1.  Download and install HP Array configuration utility from below path.

CentOS: HP Array Configuration Utility CLI for Linux  (Download Part-1)

Windows: HP ProLiant Array Configuration Utility (CLI) for Windows

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=468781&prodTypeId=18964&prodSeriesId=468780&swLang=8&taskId=135&swEnvOID=1005

2.   2   Install Array configuration Utility in server (Windows or linux as applicable)

3.   3.   Run Array Configuration Utility as applicable

hpacucli or hpacucli.exe

4.  4.    Verify current raid level of server, and check if it’s RAID 0. And if only one physical drive is added to Logical drive or both physical drive is added to Logical drive.

=> controller slot=0  show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 5001438010FA0BB0)

   array A (SAS, Unused Space: 0 MB)

      logicaldrive 1 (279.4 GB, RAID 0, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 300 GB, OK)

   unassigned

      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 300 GB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 5001438010FA0BBF)

5.    5.  If RAID Level is 0 and you have one unassigned physical drive as above, run below command. If not proceed to step 7.

=> controller slot=0 array A add drives=allunassigned

6.  6.    Above command will take 2-3 hours to add the unassigned drive in logical drive. To check status

=>  controller slot=0 logicaldrive 1 show status

   logicaldrive 1 (279.4 GB, RAID 0): Transforming, 1% complete

Once Transformation is complete go to next step.

controller slot=0 logicaldrive 1 show status

   logicaldrive 1 (279.4 GB, RAID 0): OK

7.   7.   Run below to change the Raid level to RAID 1+0. RAID 1 is same as RAID 1+0 in 2 disk setup.

=>  controller slot=0 logicaldrive 1 modify raid=1 stripsize=256

            The above command will take 2-3 hours to execute. Check the status by running below.

=>  controller slot=0 logicaldrive 1 show status

   logicaldrive 1 (279.4 GB, RAID 1): Transforming, 4% complete

            Once Raid transformation is complete. Go to next step.

            =>  controller slot=0 logicaldrive 1 show status

            logicaldrive 1 (279.4 GB, RAID 1): OK

8.  8.    Check status

=> controller slot=0  show config

Smart Array P410i in Slot 0 (Embedded)    (sn: 5001438012494E00)

   array A (SAS, Unused Space: 0 MB)

      logicaldrive 1 (279.4 GB, RAID 1, OK)

      physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 300 GB, OK)

      physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 300 GB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250 (WWID: 5001438012494E0F)

           

9.     9. Check all services are running, properly in server as before.
