Automating Disk Configuration

To automate the configuration of internal magnetic disks when you insert the disk into a

slot (or, if the system is down, when the next system load occurs), use the ALTER

SUBSYS command to set the AUTOCONFIGURE attribute (page 14-88).

Automatic configuration enables the system to automatically configure an internal disk

when initially detected after a system load, processor reload, or disk insertion.

When the AUTOCONFIGURE attribute is set to on, the system configures the disk

using the profile stored in the system configuration database. The disk profile used is

$ZZSTO.INTERNAL-DISK, unless you have configured a custom profile for a specific

enclosure. See Configuring Custom Profiles on page 6-9.

Plug and play not only configures a disk automatically but also automatically labels an

unlabeled disk, starts the disk, and revives a mirrored disk.

Limitations of Automatic Configuration

•

You cannot automatically configure model 45xx disks in a modular disk subsystem.

•

You cannot automatically configure virtual disks.

•

You cannot use AUTOCONFIGURE with enclosure interleaving if either of these is

true:

Two internal disks of a mirrored volume are installed in separate enclosures.

The adapters that are connected to the two 45xx disks of a mirrored disk

volume are installed in separate enclosures.

For more information about enclosure interleaving, see the NonStop S-Series

Planning and Configuration Guide.

Enabling Automatic Disk Configuration

1. View the automatic configuration attributes that are enabled for the system:

-> INFO SUBSYS $ZZSTO

2. To automate configuration for internal disks:

-> ALTER $ZZSTO, AUTOCONFIG ON

Note. HP does not recommend using AUTOCONFIGURE with M8xxx disks in a disk-drive

enclosure.
