Storage Subsystem SCF Attributes for FCDM
Connections
Storage Subsystem SCF Attributes for FCDM 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 FCDM’s shelf number. shelf is in the range 1 though 4. Shelf numbers
2 though 4 designate daisy-chained FCDMs. FCDMs 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.
Relationship to Fibre Channel Tape Drives
For NonStop S-series systems, the FCSA provides direct connectivity to Fibre Channel
tape drives. For information about installing and configuring Fibre Channel tape drives,
refer to the manual for the particular tape drive product. For information about the
Fibre Channel tape drives supported for direct connection to an FCSA, refer to the
NonStop S-Series Hardware Installation and FastPath Guide.
