Dell iDRAC Service Module 5.3.0.0 User’s Guide
Software RAID configuration
Using the Software RAID feature on iDRAC Service Module (iSM), you can enable the configuration of PERC S140, S150, and S160 software RAID controllers on Dell PowerEdge 14G and later generation of PowerEdge servers. Software RAID configuration enables creation and deletion of virtual disks of software RAID volumes RAID 0, RAID 1, RAID 5, and RAID 10 on Microsoft Windows operating systems.
The operating system administrator can run the dcismcfg commands on the host operating system to create and delete virtual disks. To notify the successful creation and deletion of the virtual disks, iSM sends the configuration events to iDRAC from the host operating system. The following table lists the dcismcfg CLI options for configuration software RAID:
| iSM utility name | CLI option | Description |
|---|---|---|
| dcismcfg.exe -swraid | -getctrl | To display the software RAID controller properties. |
| dcismcfg.exe -swraid | -ctrlID=0/1 -getpd | To display the physical disk properties that are managed by the controller 0 or 1. |
| dcismcfg.exe -swraid | -ctrlID=0/1 -getvd | To display the virtual disk properties that are managed by the controller 0 or 1. |
| dcismcfg.exe -swraid | -getpd | To display the physical disk properties. |
| dcismcfg.exe -swraid | -getvd | To display the virtual disk properties. |
| dcismcfg.exe -swraid | -getSWRAIDfeatureState | To display the current software RAID feature status. |
| dcismcfg.exe -swraid | -ctrlID=0/1 -createVD/-cvd -raidlevel/-rl -pdisk/-pd=<Disk ID> -vdName/-vdn -size/-s -rwpolicy/-rp -wpolicy/-wp -diskCachePolicy/-dcp | Ensure to split the IDs of multiple physical disks with a comma.
Virtual disk name (-vdName), virtual disk size (-size), read policy (-rwpolicy), write policy (-wpolicy), disk cache policy (-diskCachePolicy), global and dedicated hot spare are optional parameters. NOTE: The
-vdName or
-vdn commands support a maximum of 32 characters.
NOTE:Configuring the virtual disk read policy, write policy, and disk cache policy are supported only on SATA drives.
