Adapter parameter -aNThe parameter -aN (where N is a number starting with zero or the string ALL) specifies the PERC5/i adapter ID. If you have only one controller it’s safe to use ALL instead of a specific ID, but you’re encouraged to use the ID for everything that makes changes to your RAID configuration. |
Physical drive parameter -PhysDrv [E:S]For commands that operate on one or more pysical drives, the -PhysDrv [E:S] parameter is used, where E is the enclosure device ID in which the drive resides and S the slot number (starting with zero). You can get the enclosure device ID using “MegaCli -EncInfo -aALL”. The E:S syntax is also used for specifying the physical drives when creating a new RAID virtual drive. |
Virtual drive parameter -LxThe parameter -Lx is used for specifying the virtual drive (where x is a number starting with zero or the string all). |

The number N of the array parameter is the Span Reference you get using “MegaCli -CfgDsply -aALL” and the number N of the row parameter is the Physical Disk in that span or array starting with zero (it’s not the physical disk’s slot!).
