Checking Disk Array Status

HP-UX

Checking Disk Array Status

One of the most important management tasks is monitoring the operation and status of the disk array.

Because it is a vital piece of your system, it is important to know how well the disk array is operating and if

any problems or failures have occurred.

To view disk array component status:

Select the desired disk array controller from the list displayed on the screen.

Select “Actions” on the menu bar.

Select “View More Information . . .”

Changing Disk Array Configuration Settings

There are a number of configuration settings that control the operation of the disk array. These settings are

usually established during installation, and once set, should rarely have to be changed.

The default settings have been selected to provide the best operation for most systems. However, if you

determine that any setting does not meet your needs, you can easily change it.

Table 3

lists the various settings that can be changed with SAM, including factors you may want to consider

before changing them.
