Figure 63 LDM volume configuration
Volume discovery function
RAID Manager supports the volume discovery function on three levels showing the relationship
between LDM volumes and the physical volumes.
•
Physical level. RAID Manager shows the relationship between PhysicalDrive and LDEV by
giving $Physical as a KEY WORD for the discovery.
•
LDM volume level. RAID Manager shows the relationship between [LDM volume and
PhysicalDrives] and LDEV by given $Volume as KEY WORD for the discovery.
•
Drive letter level. RAID Manager shows the relationship between [Drive letter and LDM volume
and PhysicalDrives] and LDEV by given $LETALL as KEY WORD for the discovery.
The KEY WORD ($Physical, $Volume, $LETALL)can be used with raidscan -find,
inqraid
, mkconf commands.
In Windows, DOS devices (for example, C:, Volume{}) are linked to a Device Object Name
(\Device\...). RAID Manager indicates as the following by abbreviating a long Device Object
Name.
•
Device Object Name of the LDM for Windows:
\Device\HarddiskVolumeX for Partition : \VolX\DskY
DskY shows that VolX are configured through HarddiskY.
•
Device Object Name of the LDM for Windows 2003/2000:
\Device\HarddiskDM-VOLumes\ ... \VolumeX for spanned volume : \DmsX\DskYs
\Device\HarddiskDM-VOLumes\ ... \StripeX for striped volume : \DmtX\DskYs
\Device\HarddiskDM-VOLumes\ ... \RaidX for Raid-5 volume : \DmrX\DskYs
DskYs shows that DmsX(DmtX,Dmr) volumes are configured through bundling multiple HarddiskY1
Y2….
•
Device Object Name of the PhysicalDrive for Windows:
\Device\HarddiskX\DR?? : HarddiskX
You can determine the relationship between LDM volumes and LDEV by given a KEY WORD to
the inqraid command.
inqraid $LETALL -CLI
