I'm utterly new to working with LSI MegaRAID controllers and I'm confused as to what RAID level I am actually running. My server is equipped with 4 disks, 4TB each and I would like to have them running in RAID-10. Searching around for some hints I've found this thread and followed the link in one of the answers.
Now, what confuses me is the output of
# megacli -LDInfo -Lall -aALL | grep RAID RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0
According to the table this should mean I am currently running RAID-1. However according to this I am running RAID-10:
# megasasctl a0 LSI MegaRAID SAS 9260-4i encl:1 ldrv:1 batt:FAULT, module missing, pack missing, charge failed a0d0 7451GiB RAID 10 2x2 optimal a0e252s0 3726GiB a0d0 online a0e252s1 3726GiB a0d0 online a0e252s2 3726GiB a0d0 online a0e252s3 3726GiB a0d0 online
My confusion on this probably couldn't be worse.What am I missing here and which output is the one to be believed?
EDIT (in reply to CharlesH's request)
The output is as follows:
# megacli -LDInfo -Lall -aall Adapter 0 -- Virtual Drive Information: Virtual Drive: 0 (Target Id: 0) Name : RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 Size : 7.276 TB Sector Size : 512 Is VD emulated : Yes Mirror Data : 7.276 TB State : Optimal Strip Size : 256 KB Number Of Drives per span:2 Span Depth : 2 Default Cache Policy: WriteBack, ReadAhead, Direct, No Write Cache if Bad BBU Current Cache Policy: WriteThrough, ReadAhead, Direct, No Write Cache if Bad BBU Default Access Policy: Read/Write Current Access Policy: Read/Write Disk Cache Policy : Disk's Default Encryption Type : None Bad Blocks Exist: No Is VD Cached: No Exit Code: 0x00
