Enclosure Connections
Storage Subsystem SCF Attributes for Disk Drive Enclosure
Connections
The SCF attributes for the paths shown in Figure 1-8 are defined as:
primarycpu, backupcpu
define the primary and backup processor locations for the DISK process pair.
primarylocation, backuplocation
define the primary and backup locations (group, module, slot) of the FCSAs for the
paths.
primarysac, backupsac
defines the primary and backup ports.
primarydeviceid
consists of two identifiers:
shelf
is the disk drive enclosure’s shelf number. shelf is in the range 1 though 4.
Shelf numbers 2 though 4 designate daisy-chained disk drive enclosures. Disk
drive enclosures that are not daisy-chained each have a shelf number of 1,
even if there can be four of them sitting on different physical racks.
bay
is the number of the disk. bay is in the range 1 through 14.
When specified in the a DEVICEID attribute, these identifiers must be enclosed in
parentheses.
Relationship to Modular Tape
For Integrity NonStop NS-series systems, the FCSA provides connectivity to SCSI tape
drives through the M8201 Fibre Channel to SCSI router. The SCF TAPE attributes
used to configure such connections are listed in TAPE Configuration on page 2-23.
