HP-UX Chapter 3. Using the ARM Command Line Utilities for HP-UX The AutoRAID software includes a set of AutoRAID Manager (ARM) command line utilities. These commands provide the ability to manage the disk array from the HP-UX command prompt rather than from SAM. The ARM commands can be used to perform a number of tasks that cannot be performed using SAM. These tasks are intended for advanced users and involve procedures such as diagnostics, performance monitoring, setting SCSI values, and disk array maintenance. CAUTION! Many of the tasks available in SAM can also be performed using the ARM utilities. These tasks are described on the following pages. It is recommended that these tasks be performed using SAM to ensure predictable results and proper operation of the disk array. You should consider using an ARM utility for these tasks only if you clearly understand how the utility works and what effect it has on disk array operation. Improper use of the ARM utilities can cause undesirable results, including loss of data. LUNs and Logical Drives. To maintain consistency with HP-UX terminology, the term LUN is used to refer to a disk array logical drive. The two terms are used interchangeably and refer to the same logical entity on the disk array. Information in man pages The procedures in this chapter summarize the use of the ARM utilities. Detailed information about the ARM command line utilities and their proper usage is included in the HP-UX operating system man pages. A man page also exists for ARMServer, the server portion of the disk array management software. To access HP-UX man pages information, type: man Substitute one of the following ARM utility names for commandname. ARMServer arraycfg arraydsp 33

Chapter 3.
Using the ARM Command Line
Utilities for HP-UX
The AutoRAID software includes a set of AutoRAID Manager (ARM) command line utilities. These
commands provide the ability to manage the disk array from the HP-UX command prompt rather than from
SAM.
The ARM commands can be used to perform a number of tasks that cannot be performed using SAM.
These tasks are intended for advanced users and involve procedures such as diagnostics, performance
monitoring, setting SCSI values, and disk array maintenance.
CAUTION!
Many of the tasks available in SAM can also be performed using the ARM
utilities. These tasks are described on the following pages. It is recommended that these
tasks be performed using SAM to ensure predictable results and proper operation of the
disk array. You should consider using an ARM utility for these tasks only if you clearly
understand how the utility works and what effect it has on disk array operation. Improper
use of the ARM utilities can cause undesirable results, including loss of data.
LUNs and Logical Drives
. To maintain consistency with HP-UX terminology, the term LUN is
used to refer to a disk array logical drive. The two terms are used interchangeably and refer to the
same logical entity on the disk array.
Information in man pages
The procedures in this chapter summarize the use of the ARM utilities. Detailed information about the
ARM command line utilities and their proper usage is included in the HP-UX operating system man pages.
A man page also exists for ARMServer, the server portion of the disk array management software.
To access HP-UX man pages information, type:
man <commandname>
Substitute one of the following ARM utility names for commandname
.
