OCCUPANCY_ALAR

The point when a deﬁned percentage of space is used. When this point is reached, an event log is

generated and sent to the management server (optionally the host system) informing the administrator that

the g roup is becoming full. Do not use the percentage sign (% ) after the number. The d efault is 95%.

SPARE_POLICY=

This parameter determines the amount, if a ny, of storage space set aside for use in the event that d isks

fail. The default is single.

• NONE—Reserves no space within a disk group to allow for da ta reconstruction in case of

failure of disk drives

NOTE:

Using a spare policy of NONE can cause data loss and is not recommended.

• SINGLE—Reserves space within a disk group to allow for data reconstruction for failure of a

single disk drive

• DOUBLE—Reserves space within a disk group to allow for data reconstruction for failure of

two disk drives

NOTE:

The space set aside is not in numbers of physical disks. It is the equivalent amount of storage space

spread across all disks.

Example

ADD DISK_GROUP “\Disk Groups\human_resources” DEVICE_COUNT=12

SPARE_POLICY=SINGLE OCCUPANCY_ALARM=75

This example creates a new disk group, human_resources. It has 12 physical disks with the equivalent

of one disk set aside as a spare and sends an event log to the array when 75% of capacity is reached.

ADD FOLDER

Use the ADD FOLDER comm a nd to create a new folder within the speciﬁed folder to aid in organizing

your array. You can create folders only under the Virtual Disks and Hosts root folders. You

cannot cr

eate root folders.

For example, if you have a controller that is ser ving Human Resources (HR) and Engineering, you could

create four folders—two to separate the virtual disks and two to separate the hosts:

• \Virtual Disks\Engineering and \Virtual Disks\HR

• \Hosts\

Engineering and \Hosts\HR

Creating these folders allows you to put engineering virtual disks and hosts in the Engineering folders

and Human Resources storage\hosts in the HR folders. This makes it easier to keep track of the

components within your array. If you want to nest folders inside folders, you must add one folder at a time.

Syntax

ADD FOLDER <folder_name>

Switch

Only the

COMMENT switch is available with the ADD FOL DER command.
