ARMServer(1M)

NAME

ARMServer — disk array server daemon.

SYNOPSIS

/opt/hparray/bin

Remarks

This command and the HP Advanced Disk Array management software are not supported on systems running HP-UX 11i Version 1.5, HP-UX 11i Version 1.6, and later versions.

DESCRIPTION

ARMServer is the server portion of the HP Advanced Disk Array management software. It monitors the operation and performance of the disk array, and services external requests from clients executing disk array commands. ARMServer monitors disk array performance and status, maintains disk array logs, initiates diagnostics, and allows clients to examine and change disk array configuration.

ARMServer must be running to allow management of the disk array using the command line utilities. Host I/Os are not dependent on ARMServer and are serviced regardless of whether it is running or not. Because of its importance in managing the disk arrays, ARMserver is launched automatically when the system is booted.

One of the most important functions provided by ARMServer is retrieving and storing performance and status information from the disk array logs. If ARMServer is not running, the disk array will continue to log data, but when the array logs are full older entries will be lost to make room for new entries. A "Log Full" warning will be displayed if this condition occurs, alerting you to the fact that ARMServer is not running.

DIAGNOSTICS

All significant changes in disk array status detected by ARMServer are entered in /var/adm/syslog/syslog.log. These entries form a history of disk array operation and can be used to track operation.

DEPENDENCIES

The arraymond disk array monitor requires ARMServer to be running to check the status of the disk array. arraymond uses the arraydsp utility to retrieve status information about the disk array at regular intervals. When performing maintenance on the disk array (for example, downloading new firmware code), arraymond can be turned off to avoid error messages generated because the disk array is not accessible. To turn off arraymond and ARMServer use the following command line:

/sbin/init.d/hparray stop 

To restart arraymond and ARMServer use the following command line:

/sbin/init.d/hparray start
