NAME

arrayfmt — formats a LUN or an entire disk array.

SYNOPSIS

arrayfmt -L LUN [-V] [-?] array-id

arrayfmt -F [-h] [-V] [-?] array-id

DESCRIPTION

arrayfmt formats the LUN (logical devices) identified by LUN or the entire disk array identified by array-id.

WARNING: This is a destructive command. Data on the selected LUN or disk array will be destroyed following successful completion of this command. Backup all vital data before performing a format.

The array-id used to address the disk array can be the disk array serial number, the character device file name of any LUN on the array (LUN 0 if no LUNs are created), or the alias text string assigned to the disk array.

Options

arrayfmt supports the following options:

-F [ -h ]: Format the entire disk array identified by array-id. By default, only disks currently included in the array configuration will be formatted. If the -h option is specified, all disks installed in the cabinet will be formatted, even those that are not included in the array configuration.
-L LUN: Format the LUN specified by LUN.
-V: Verbose mode displays additional command execution, state, and/or status messages.
-?: Display expanded usage message. This option overrides all others.

EXTERNAL INFLUENCES

Environment Variables

LC_MESSAGES determines the language in which messages are displayed. The current language settings can be checked with locale(1).

RETURN VALUE

arrayfmt returns the following values:

0: Successful completion.
1: An error in execution (I/O, subsystem, security, etc.) occurred.
2: An error in command syntax occurred: for example, an unknown command-line option was passed.
3: Timeout in communication to server. May indicate ARMServer is not running.

DIAGNOSTICS

The following messages can be generated by arrayfmt:

Usage: arrayfmt {-L LUN | -F [-h]} [-V] [-?] <array-id>

An error in command syntax has occurred. Re-enter the command with all necessary arguments.

arrayfmt: Arg out of range

One of the arguments has exceeded its maximum or minimum size, or is incorrect in form. Check the size and form of each argument.

arrayfmt: Unknown argument

An invalid argument was specified. Check command usage.

arrayfmt: No such file or directory

The specified array-id does not exist or does not identify a disk array that is communicating with the system. Verify the correct array-id with ioscan(1M).

arrayfmt: Error in command execution, <Additional Error Info>: 
<Error Info Decode> 

The command failed due to a device error, an internal error, or a system error. The Additional Error Info and Error Info Decode fields will hold specifics about the failure and its cause.

arrayfmt: Cannot format array while a diagnostic is running.

An attempt was made to format the array while a diagnostic was in progress. Allow the diagnostic to complete or cancel the test using dteststat.

arrayfmt: Device was just powered-on or reset.

A command failed because the disk array has been powered-on or reset. Reissue the command and it should succeed.

EXAMPLES

Format LUN 1 on disk array serial number 00786b5c0000:

arrayfmt -L 1 00786b5c0000 

Format the entire disk array identified by device file /dev/rdsk/c2t0d0:

arrayfmt -F /dev/rdsk/c2t0d0 

DEPENDENCIES

ARMServer must be running to execute this command. See ARMServer(1M).

SECURITY CONFIGURATION

This command is modified for all security configurations.

Security Behavior/Restrictions

Use of this command is restricted to authorized users only.

Command Authorizations

This command requires the sysadmin authorization to successfully execute.

Privileges

The command has been modified to support least privilege. The potential privileges possessed by the command and their uses include:

allowdacread: This privilege is raised to provide discretionary read access to the devices.
allowdacwrite: This privilege is raised to provide discretionary write access to the devices.
allowmacread: This privilege is raised to provide mandatory read access to the devices.
allowmacwrite: This privilege is raised to provide mandatory write access to the devices.
filesysops: This privilege is raised to allow the mknod(2) system call to succeed.
writeaudit: The command generates its own audit records and submits these directly to the system audit trail. This privilege is raised whenever the command needs to write an audit record.
