Description
Explain how the fibre channel controller ports on an Sun StorageTek[TM] 5320 NAS head are numbered (isp numbering/sequencing) and how it is related to LUN path.

Steps to Follow
STK 5320 NAS heads can have up to 2 dual-port 2Gb/s FC PCI HBAs.

From factory the two FC HBAs are installed in PCI Slots 0 and 1 - the two leftmost PCI slots while viewed from rear. There are a total of 5 PCI slots on a 5320 NAS head and they are labeled as PCIX 0, PCIX 1, PCIX 2, PCIX 3, PCIX 4, from left to right.

The four FC ports of the two dual-port FC HBAs are named "isp1", "isp2", "isp3", and "isp4" by the NAS OS and the "isp[1-4]" notation is part of the LUN designation built by the NAS OS (e.g. "isp1d043").

Numbering of "isp[1-4]" is done as follows:

       isp1 - Upper FC port of the HBA in PCI 1
isp2 - Lower FC port of the HBA in PCI 1
isp3 - Upper FC port of the HBA in PCI 0
isp4 - Lower FC port of the HBA in PCI 0

The second parameter used in the LUN designation/LUN path is the "SID" or the loop ID of the FC port, when the port sees storage via fibre channel. Output of the command "hbainfo" shows the "SID" information.

The third parameter in the LUN designation is the LUN number---assigned to each LUN when it is created on the storage subsystem.

The LUN path is expressed by the NAS OS as "<ISP#>/<SID>", e.g. "1/4", "2/0".

The LUN is designated as "isp<ISP#>d0<SID><LUN#>", e.g. "isp1d040", "isp2d001".

Here is a sample output of the "hbainfo" command:
