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
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.
