-> INFO $S11500
5. See “Starting an Open SCSI Device” (page 177).
Adding a Similar Open SCSI Device to This System
To add another Open SCSI device similar to an existing device, use the LIKE attribute:
-> ADD SCSI $S11501, LIKE $S11500, PRIMARYLOCATION (11,1,51)
Adding a Similar Open SCSI Device to Another System
To configure the same or a similar Open SCSI device on another system, create a command file
by using the OBEYFORM attribute of the INFO DISK command. You can copy this file to another
system or add it to different configuration file on the current system.
1. Capture the configuration for an existing Open SCSI device:
-> INFO / OUT LOG / $S11502, OBEYFORM
== STORAGE - Detailed Info SCSI in obeyform: \COMM.$S11502
ADD SCSI $S11502 , &
SENDTO STORAGE , &
BACKUPCPU 0 , &
HIGHPIN ON , &
LUN 0 , &
MAXOPENS 4 , &
NUMIO 8 , &
PRIMARYCPU 1 , &
PRIMARYLOCATION (11,1,50) , &
PRIMARYSAC 5 , &
PROGRAM $SYSTEM.SYSTEM.TDSCSI , &
RECSIZE 57344 , &
SCSIID 2 , &
STARTSTATE STARTED , &
STRUCTAREASIZE 24 , &
TRACEBUFLEN 33 , &
TRACELEVEL 65535
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
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.
