• An argument must directly follow the option or subcommand it is modifying and is required

on the command line, unless otherwise specified (for example: removealert –i

<alert_ID>).

• Multiple options and arguments on a command line are separated with a space.

• Specifiers follow options.

• User supplied input is identified by angled brackets (< >).

• Unless noted otherwise, valid character formats include alphanumeric characters, periods,

dashes, and underscores. In general, the following length limits are enforced by the HP 3PAR

OS CLI:

◦ virtual volume name ≤ 31 characters

◦ Thinly Provisioned Virtual Volume (TPVV) name ≤ 31 characters

◦ virtual copy names ≤ 31 characters

◦ logical disk name ≤ 31 characters

◦ host name ≤ 31 characters

◦ Common Provisioning Group (CPG) name ≤ 31 characters

◦ template name ≤ 31 characters

◦ domain name ≤ 31 characters

◦ snapshot name ≤ 31 characters

◦ user name ≤ 31 characters

◦ system name ≤ 31 characters

Glob-Style Pattern

Several of the commands in this reference allow a pattern to be specified to refine the output of

the commands. The patterns are used to match against a string. Strings are typically names such

as host or virtual volume names. For example, in the showhost host_name|pattern...

command, a pattern can be specified to refine the command output for a string of host names

matching the specified pattern.

The pattern specifier, as used in the CLI commands, is specified in the form of a glob-style pattern.

Glob-style matching in the CLI is implemented by Tcl. A glob-style pattern consists of the symbols

in the following table.

Explanation of ActionSymbol

a null string.

Matches any single character in a string.?

Matches any character in the set given by chars. A range

of chars can be specified using a dash (–). For example,

[a–z] represents all the ASCII characters from a through z.

[chars]

Matches the single character x.\x
