arrayinfo(1M)

NAME

arrayinfo − describe general characteristics of a disk array

SYNOPSIS

arrayinfo [-j |-m |-s |-ar |-dr] device_file

DESCRIPTION

arrayinfo displays summarized information for the SCSI disk array associated with the character device file device_file.

By default arrayinfo returns the following information:

• array vendor ID

• array product ID

• number of attached disk mechanisms

• vendor/product type of attached disk mechanisms. (Assumes all are the same type)

NOTE: The array vendor ID, and product ID information are constant, regardless of the type and quantity of disks attached.

Options:

arrayinfo recognizes the following options:

-j Displays the current setting of certain jumper switches on each disk mechanism, including:

• Automatic Spin Up ( 0 Disable / 1 Enable )

• Parity Error Detect ( 0 Disable / 1 Enable )

• Unit Attention ( 0 Enable / 1 Disable )

• Initiate Synchronous Data Transfer ( 0 Disable / 1 Enable )

• SCSI target address of the mechanism

-m Displays array mapping information, including:

• The disk vendor, and model type of each disk in the array

• The current status of each disk in the array, as determined by the array controller.

• The array sub-channel, and sub-channel addresses for each disk in the array.

-s Displays serial numbers. This option displays serial number information for the disk array controller, and all attached disk mechanisms.

-ar Displays array revision information. This option displays revision information for the hardware, firmware, and software of the array controller.

-dr Display disk revisions. This option displays revision information for the hardware, and firmware of each disk in the array.

RETURN VALUE

arrayinfo returns the following values:

0 Successful completion

-1 Command failed (an error occurred).

DEPENDENCIES

This utility is only compatible with HP C2430 disk arrays.

Series 700:

arrayinfo must be used with a device file mapped to a unit address that is not in use by the array controller (unconfigured). By convention unit addresses 6 and 7 should not be configured. Array information should be accessible by addressing either of these unit addresses.

Series 800:

Any device file ( LU ) that is mapped to the disk array can be used to access the array information.
