ADD RAIDSET

Creates a RAIDset from a number of containers.

Format

ADD RAIDSET

container-name container-name1 container-name2 [container-nameN]

Parameters

container-name

Speciﬁes the name that is used to refer to this RAIDset. The name must start

with a letter (A–Z) and can then consist of up to eight more characters made up

of letters A–Z, numbers 0–9, periods (.), dashes (-), or underscores (_), for a total

of nine characters.

container-name1 container-name2 container-nameN

The containers that will make up this RAIDset. A RAIDset may be made up of

from 3 to 14 containers.

Description

Adds a RAIDset to the list of known RAIDsets and names the RAIDset. This

command must be used when a new RAIDset is to be added to the conﬁguration.

Qualiﬁers

POLICY=BEST_FIT

POLICY=BEST_PERFORMANCE (Default)

NOPOLICY

Speciﬁes the replacement policy to use when a member within the RAIDset fails.

BEST_FIT gives highest priority to ﬁnding a replacement device within the

spareset that most closely matches the sizes of the remaining members of the

RAIDset. After ﬁnding the most closely matching devices, the device that gives

the best performance is selected.

BEST_PERFORMANCE (default) gives highest priority to ﬁnding a replacement

device within the spareset that results in the best performance of the RAIDset.

After ﬁnding the best performing devices, the device that most closely matches

the size of the remaining members of the RAIDset is selected.

NOPOLICY retires a failing device from the RAIDset without selecting a

replacement. This causes the RAIDset to run in a reduced state until a BEST_

FIT or BEST_PERFORMANCE policy is selected, or a member is manually

replaced in the RAIDset (see SET raidset-container-name).

RECONSTRUCT=NORMAL (Default)

RECONSTRUCT=FAST

NORECONSTRUCT

Speciﬁes the speed at which a RAIDset will be reconstructed when a new member

is added to the RAIDset or immediately after the RAIDset is initialized.

RECONSTRUCT=NORMAL (default) balances overall performance of the

controller against the demand of reconstructing the RAIDset.
