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:
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.
