68 Configuring a Storage Array with Disk Pools
Example of Creating Volumes with User-Assigned Drives
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “create diskpool drives=(1,1,1 1,1,2 1,2,3 ...
2,1,10, 2,2,11)

userLabel=”Engineering_1” warningthreshold=65
criticalthreshold=75 criticalpriority=high
backgroundpriority=medium degradedpriority=high
securitytype=enabled drivemediatype=hdd
dataassurance=enabled;”
This command creates a disk pool with these features:

The list of drives represents the drives found in a high capacity drive tray.

The name of the disk pool is Engineering_1. The disk pool name can be any
combination of alphanumeric characters, hyphens, and underscores. The
maximum length of the disk pool name is 30 characters. You must enclose the
disk pool name with double quotation marks (“ ”).

When you assign drives to a disk pool, you do not need to use the
driveCount
parameter.

When the disk pool consumes 65 percent of its capacity, a warning alert is posted.
The default value is 50 percent. The
warningthreshold
parameter always
must be set to a value lower than the
criticalthreshold
parameter.

When the disk pool consumes 75 percent of its capacity, a critical alert is posted.
The default value is 85 percent.

The priority for reconstruction operations for critical events on the disk pool is
set to high. If a critical condition occurs, such as two drives failing at the same
time, the storage management software makes the reconstruction of the data a
high priority.

The priority for background operations on this disk pool is set to medium. If a
background operation occurs, such as reconstruction or formatting, the
background operation equally shares resources with other storage array
operations.

The priority for correcting the disk pool after it has entered a Degraded state is set
to high. If a condition occurs, such as a single drive failure, the storage
management software makes the correction of the condition a high priority.

The
securitytype
is enabled, so the storage management software uses only
drives that are configured to be security drives.

The type of drive to be used is a hard drive (hdd).

The disk pool uses only drives with protected data capability.
Using the Create
Volume Command
The
create volume diskPool
command enables you to create a volume in a
disk pool. You can create either one of these types of volumes:

Standard volume

Thin volume
