Configuring a Storage Array

55

For optimal performance in a multi-user database or file system storage

environment, set the segment size to minimize the number of physical disks

needed to satisfy an I/O request. Using a single physical disk for a single request

leaves other physical disks available to simultaneously service other requests.
After you have finished creating the disk groups and virtual disks by using the

autoConfigure storageArray

command, you can further define the properties

of the virtual disks in a configuration using the

set virtualDisk

command.

(See "Modifying Your Configuration" on page 55.)

Example of the Auto Configuration Command

client>smcli 123.45.67.89 -c "autoConfigure
storageArray physicalDiskType=SAS raidLevel=5
diskGroupWidth=8 diskGroupCount=3
virtualDisksPerGroupCount=4 hotSpareCount=2
segmentSize=8;"

The command in this example creates a storage array configuration that uses

SAS physical disks set to RAID level 5. Three disk groups are created. Each disk

group consists of eight physical disks configured into four virtual disks. The

storage array has two hot spares, and segment size for each virtual disk is 8 KB.

Modifying Your Configuration

After creating your initial configuration, modify the properties of the

configuration to ensure that it meets your requirements for data storage. Use

the following commands to modify the properties of your configuration:

• autoConfigure storageArray
• create virtualDisk

Use the

set

commands to modify a storage array configuration. This section

explains how to modify the following properties:

• Storage array password
• Simple Mail Transport Protocol (SMTP) and Simple Network

Management Protocol (SNMP) alerts

• RAID controller module clocks
• Storage array host type
• Global hot spares
