56 Configuring a Storage Array with Volume Groups
 volumeGroups
– Removes the storage array mapping (volume configuration,
the volume group configuration, disk pools, and thin volumes), but leaves the rest
of the configuration intact.
If you want to create new volume groups and volumes within the storage array, you
can use the
clear storageArray configuration
command with the
volumeGroups
parameter to remove existing volume groups in a pre-existing
configuration. This action destroys the pre-existing configuration. Use the
clear
storageArray configuration
command only when you create a new
configuration.
Configuring a
Storage Array
with Volume
Groups In general, you configure a storage array by defining a volume group and its
associated RAID level, defining the volumes, and defining which hosts have access to
the volumes. This chapter explains how to use the script commands to perform the
general steps to create a volume group configuration from an array of drives.
NOTE
Many of these commands require a thorough understanding of the firmware as
well as an understanding of the network components that need to be mapped. Use the
CLI commands and the script commands with caution.
Using the Auto
Configure
Command
The
autoConfigure storageArray
command creates the volume groups on a
storage array, the volumes in the volume groups, and the hot spares for the storage
array. When you use the
autoConfigure storageArray
command, you define
these parameters:

The type of drives (Fibre, SATA, or SAS)

The RAID level

The number of drives in a volume group

The number of volume groups

The number of volumes in each volume group

The number of hot spares

The size of each segment on the drives

A read ahead multiplier
After you define these parameters, the SANtricity ES Storage Manager software
creates the volume groups, the volumes, and the hot spares. The controllers assign
volume group numbers and volume numbers as they are created. After the SANtricity
ES Storage Manager software creates the initial configuration, you can use the
set
volume
command to define volume labels.
Before you run the
autoConfigure storageArray
command, run the
show
storageArray autoConfigure
command. The
show storageArray
autoConfigure
command returns a list of parameter values that the SANtricity
ES Storage Manager software uses to automatically create a storage array. If you
