NAME
DEVCONF.TXT - Diagnostic station: Defines the devices that
are attached to each node of a Paragon system.
SYNOPSIS
/usr/paragon/boot/DEVCONF.TXT
DESCRIPTION
The file DEVCONF.TXT is on the diagnostic station and can be
created or changed by the system administrator only.
This reset command and the Paragon diagnostic utilities read
the file DEVCONF.TXT to determine what devices are attached
to the nodes in a Paragon system. This file must exist
before executing the reset script with the autocfg switch.
The file DEVCONF.TXT resides on the diagnostic station. This
file contains a list of strings that specify the following
devices for a Paragon system:
o Ethernet devices.
o Hard disks.
o Hippi devices.
o MIO boards.
o Paging devices.
o RAID devices.
o Tape devices.
You use the following strings in the file SYSCONFIG.TXT:
DEVICES Specifies the beginning of a list of strings that
define the system devices.
DISK cbs ID id name
Specifies a node with a stand-alone hard disk dev-
ice. This species the hard disk's
cabinet-backplane-slot (CBS) location, SCSI ID,
and the manufacturer's name (for example, MAXTOR).
END_DEVICES
Specifies the end of a list of strings that define
the system devices.
ENET cbs Specifies a node with an Ethernet port at the CBS
location specified by the cbs argument.
HIPPI cbs rev
Specifies a node with an HIPPI board at the CBS
location specified by the cbs argument. The rev
argument specifies the revision number of the
HIPPI board.
MIO cbs rev
Specifies a node with an MIO board at the CBS
location specified by the cbs argument. The rev
argument specifies the revision number of the MIO
board.
NOPAGER Removes the node number from the list of nodes
that can be used for paging. Any node that is
defined to have a hard disk attached is automati-
cally listed as a potential paging node. This
token overrides this.
PAGE_TO device
Specifies that the device attached to a node is
used for paging. By default, all paging uses the
device rz0b. The node is added to the list of node
numbers in the bootmagic string PAGE_TO. The
PAGE_TO string has no effect on the boot node. The
boot node uses the default paging device rz0b.
RAID cbs ID id SW rev LV level DC count SID sid name
Specifies a node with a RAID at the CBS location
specified by the cbs argument. The id argument
specifies the SCSI ID for the RAID. The rev argu-
ment specifies the revision number of the RAID
software (for example, 3.02). The level argument
specifies the RAID level. The value of the level
argument must 0, 1, 3, or 5). The count argument
is the number of devices in the RAID. The name
argument is the symbolic name of the device that
is written to the file SYSCONFIG.TXT.
TAPE cbs ID id name
Specifies a node with a tape device at the CBS
location specified by the cbs argument. The id
argument specifies the SCSI ID for the tape dev-
ice. The name argument is the symbolic name of the
device that is written to the file SYSCONFIG.TXT.
EXAMPLES
The following is an example DEVCONF.TXT file that defines
the devices on a Paragon system:
DEVICES
ENET 00D02
ENET 00D03
RAID 00D03 ID 0 SW 3.02 LV 5 DC 5 SID 0 RAID3
TAPE 00D03 ID 6 DAT
RAID 01D12 ID 0 SW 3.02 LV 5 DC 5 SID 0 RAID3
MIO 00D03 H04
MIO 00D02 H04
MIO 01D12 H04
END_DEVICES
This example defines the following:
o Two nodes with Ethernet ports at the CBS locations 00D02
and 00D03.
o Two nodes with level 3 RAIDs at the CBS locations 00D03
and 01D12.
o One node with a DAT tape at the CBS location 00D03.
o Three nodes with MIO boards at the CBS locations 00D02,
00D03, and 01D12.
