ADD Stripeset, 24CLI Commands, Stripeset-name | Compaq HSZ80

5–24CLI Commands

ADD STRIPESET

Names a stripeset and adds it to the controller configuration. Stripesets are sometimes referred to as RAID level 0 storagesets. The number of members in the stripeset is determined by the number of container-nameparameters specified.

Syntax

ADD STRIPESET stripeset-name container-name1 container-name2 [container-nameN]

Parameters

stripeset-name

Assigns a name to the stripeset. This is the name used with the ADD UNIT command to identify the stripeset as a host-addressable unit.

container-name1 container-name2 [container-nameN]

Identifies the members (disk drives or mirrorsets) making up the stripeset. Stripesets can contain between 2 and 24 members.

The container name must start with a letter (A through Z) and may consist of a maximum of nine characters including letters A through Z, numbers 0 through 9, periods (.), dashes (-), or underscores (_).

IMPORTANT: It is common to name a stripeset STRIPEn, where n is a sequen- tially assigned, unique identifier. This naming convention presents to the user both the type of container and its unique identifier.

NOTE: A 240-character limit exists for the command line. If you are configuring a stripeset with multiple members (for example, more than 20), you will have to rename the members in order to execute the command.
