Volume Configuration; Raid Disk Creation - American Megatrends StorTrends User’s guide User Manual

Volume Configuration

Initial volume configuration can be done in three stages.

1. RAID Disk Creation

At the base level is the RAID CONTROLLER.
CLI> list –-type or –t controller
raid <Enter>
Example: list –t controller raid
This will list the available RAID controllers in the system. By default, Software MD will be shown as a RAID
controller with controller number "0". If Hardware RAID controllers present, then they will take precedence
over Software MD.
CLI> list –-type or -t PD
--controllerno or -n 0
raid <Enter>
Example: list –t pd –n 0 raid
This will list the PD's that are available for configuration in controller number zero. PD's can be grouped
through a RAID level to form a Logical disk – LD.
CLI>create –-type or -t LD
–-stripesize or -p 64
–-diskname or -d /dev/sda (use –d 1 or –d 2...15 on a 3U)
–-diskname or –d /dev/sdb
–-diskname or –d /dev/sdc
–-diskname or –d /dev/sdd
--raidlevel or –r 0
--controllerno or –n 0
--cachemode or –m 3
raid <Enter>
Example: create –t ld –p 64 –d 1 –d 2 –r 1 –n 0 –m 2 raid
This will create a RAID 1 Logical Disk – LD with 64K-chunk size and two disks on a 3U.
Example: create –t ld –p 64 –d /dev/sda –d /dev/sdb –d
/dev/sdc –r 5 –n 0 –m 1 raid
This command will crate a RAID 5 Logical disk – LD with 64 k chunk size and three disks on a 1U box.
CLI> list –-type or –t LD
raid <Enter>
Example: list –t ld raid
This will list the available RAID LD's present in the system.
