The Fibre Channel Protocol (FCP) adapters are specified by their System Adapter Identification (SAID).
When you create remote mirror and copy paths over FCP links, you
must specify the world wide node names (WWNNs) of the source (or local) and
target (or remote) storage units. The WWPN and the SAIDs of the source and
destination adapters are used to generate a World Wide Port Name (WWPN). The
WWPN is used for communicating to the remote storage unit.
The SAID on
the source storage unit identifies the location of the associated storage
unit. The first value is zero and the last two values are hexadecimal SAID
byte values that correspond to FCP interfaces. FCP adapters are specified
by their SAID numbering scheme. Figure 1 shows
a fibre-channel interface identification diagram. DS6000
only has two adapters: B00 and B06.
The
enclosure numbers (EE) are for expansion frames (from the back), slot 0 adapter
ID. All values are shown in hexadecimal values and they apply to all models.
The following categories apply to Figure 1:
- Adapter ID
- Displayed as 0B00 plus EE*6 plus slot
- Logical name
- Displayed as cpssfcEESP (enclosure, slot, port)
- SAID
- Displayed as 0xEESP
- Device adapters
- Logical names are displayed as issEESP and adapter IDs are displayed as 0x10XX.
Table 1 displays the SAIDs for the associated racks.
