Create RAID Disk using hpacucli in Linux


1. CHECK UNASSIGNED DRIVES THAT CAN BE USED 

server1:~ # hpacucli
HP Array Configuration Utility CLI 8.70-8.0
Detecting Controllers...Done.
Type "help" for a list of supported commands.
Type "exit" to close the console. 
 => hpacucli ctrl all show config 

Smart Array P400 in Slot 9 (sn: P61XXXXXXXXXN)
 array A (SAS, Unused Space: 0 MB)
 logicaldrive 1 (68.3 GB, RAID 1+0, OK)
 physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
 physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)
 unassigned      
 physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 146 GB, OK)  
 physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 146 GB, OK) 

Note: Last two drives in the output are free and we gonna use them to create RAID  


2. NOW WE ARE GOING TO CREATE RAID 1+0 DISK ARRAY 

=> hpacucli ctrl slot=9 create type=logicaldrive drives=1I:1:3,1I:1:4 raid=1

3. VERIFY THAT THE DISK ARRAY WAS CREATED 

hpasmcli> hpacucli ctrl all show config
 Smart Array P400 in Slot 9 (sn: P61XXXXXXXXXN)
 array A (SAS, Unused Space: 0 MB)
 logicaldrive 1 (68.3 GB, RAID 1+0, OK)
 physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
 physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)
 array B (SAS, Unused Space: 0 MB)   ß NEW DISK ARRAY
 logicaldrive 2 (136.7 GB, RAID 1+0, OK)
 physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 146 GB, OK)
 physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 146 GB, OK) 


VERIFY NEW DISK DRIVE WAS CREATED IN OS LEVEL (LINUX)

server1# cat /proc/driver/cciss/cciss0
