Configure the SCSI Extenders
1. Ensure that both SCSI extenders are installed properly.
2. Save the current $SYSTEM.ZSYSCONF.CONFIG file using the SCF SAVE
command. The SAVE command is described in the SCF Reference Manual for G-
Series RVUs.
3. For each SCSI extender, use the SCF ADD SCSI command to add the SCSI
extender to the system configuration database.
This example adds a SCSI-to-Fiber extender (CTSFE) named $SFROUT1:
-> ADD SCSI $SFROUT1,SENDTO STORAGE,PRIMARY LOCATION
(1,1,52),PRIMARYSAC 2,PRIMARYCPU 0,BACKUPCPU 1,SCSIID 8
In this example:
•
The name $SFROUT1 is an example; however, you can use any device name.
•
The SENDTO STORAGE attribute specifies the subsystem in which to install
the SCSI extender.
•
The PRIMARY LOCATION attribute specifies the location (group, module, and
slot) of the CRU (adapter) to which the SCSI extender is attached.
•
The PRIMARYSAC attribute is necessary when using ServerNet/DA with a
S-SAC.
•
The PRIMARYCPU attribute specifies the primary processor.
•
The BACKUPCPU attribute specifies the backup processor.
•
The SCSIID attribute shows the SCSIID that is configured for the SCSI
extender. This ID must be set to 8 for a SCSI-to-Fiber extender (CTSFE).
Note. The ID for a SCSI-to-Fiber extender (CTSFE) is preconfigured to 8 and must not be
changed.
