group
(NonStop S-series server)
is the 2-digit number that identifies the IOAM enclosure that contains the FCSA.
Range of ValuesDescriptiongroup
01-08The object is in processor
enclosure n.

group
(Integrity NonStop NS-series server)
is in the range 110 through 115.
module
identifies whether the FCSA is installed in module 2 or 3 of an IOAM enclosure. A
module is either 2 or 3.
slot
is the FCSA physical slot number in the IOAM. The slot number depends on server
model.
sac
identifies one of the ServerNet Addressable Controllers (SACs) inside the FCSA. SACs
are designated either 1 or 2.
number
indicates the position of the device within the system.
Relationship to the Enterprise Storage System (ESS)
The FCSA provides connectivity to the ESS. Certain attributes of the adapter are automatically
added to the system configuration database, but you must configure the paths to the disks.
To perform the ADD DISK task (see Disk Configuration (ESS Connection) on page 2-14), you
must coordinate with the ESS administrator and the FC switch administrator (if an FC switch is
used) to receive information about the following attributes specified in the ADD DISK command:
• ESS port worldwide names (WWN)
• ESS logical unit numbers (LUNs)
In addition, you must provide the WWNs of the Fibre Channel ports on the FCSA to the FC
switch and ESS administrators so that they can update the host group WWNs in the ESS and the
zones in the SAN. This allows the new FCSA to be recognized by the FC switch and the ESS.
NOTE: Adding or updating WWNs in the ESS and SAN zones is not required if the FCSA ports
are directly connected to the ESS Fibre Channel ports.
Figure 1-5 shows an example of two paths from the processors through the FCSAs to the storage
subsystem. More complicated paths are likely, but Figure 1-5 relates the SCF attributes to the
storage subsystem path. The SCF attributes shown in the figure are discussed after the figure.
