Adding an Open SCSI Device

Adding an Open SCSI Device

To add an Open SCSI Fibre Channel device, you do not specify a SCSI ID. Instead,
you specify the PRIMARYPORTNAME (WWN) and LUN of the device. The SCF ADD
SCSI command adds an Open SCSI Fibre Channel device to the system:

-> ADD SCSI $EXT8, SENDTO STORAGE, PRIMARYLOCATION (111,2,5) &
-> PRIMARYSAC 1, PRIMARYPORTNAME 2000003E00452211, LUN 1

Issue the SCF INFO SCSI command to verify that the Open SCSI device has been
properly configured. For examples and descriptions of the INFO SCSI reports, see

Viewing Configuration Information About Open SCSI Devices

on page 4-1. For more

detailed information, refer to the SCF Reference Manual for the Storage Subsystem.

Altering Open SCSI Attribute Values

The SCF ALTER SCSI Command alters the attributes of an Open SCSI device in the
system configuration database. For a description of alterable Open SCSI attributes,
see the SCF Reference Manual for the Storage Subsystem.

Before you use the SCF ALTER SCSI command, review the ALTER SCSI
considerations in the SCF Reference Manual for the Storage Subsystem.

To display the results of the changes you have made, see

LUN

is the logical unit number (LUN) of the device used by the
IOP to select any additional devices that are attached to the
device.

SAC Name

is the name of the SAC on the adapter, determined by the
location of the adapter in the system.

SAC Number

is the subdevice number of the SAC on the adapter which
determines which SCSI bus accesses the device.

SCSI ID / Portname

For Open SCSI devices, the SCSI ID that the IOP uses to
access the device.

For Open SCSI Fibre Channel devices, the world wide name
that the IOP uses to access the device.

Note.

You can optionally specify a backup path consisting of BACKUPLOCATION,

BACKUPSAC, and BACKUPPORTTNAME. However, there is no backup LUN. The same LUN
is used for both the primary and backup paths.
