Adding an Open SCSI Fibre Channel Device
1. Capture the configuration for an existing Open SCSI device:
-> INFO / OUT LOG / $S11502, OBEYFORM
2. Optionally edit the resulting log file to specify:
•
A unique device name
•
Based on physical location, change at least one of:
°
PRIMARYLOCATION and, optionally, MIRRORLOCATION slot numbers
°
PRIMARYSAC and, optionally, MIRRORSAC SAC numbers, if the new
locations use different SACs
°
SCSIID value
3. Enter the log file contents either by copying and pasting into an SCF command line
or by using the log file as a command file.
Adding an Open SCSI Fibre Channel 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.
This 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
Altering Open SCSI Attribute Values
The ALTER SCSI Command (page 14-59) alters the attributes of an Open SCSI device
in the system configuration database. For a description of alterable Open SCSI
attributes, see page 14-60.

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.
