The first domain has only two devices: the SAS initiator and a SAS end device (a disk). The second domain has expanders, SAS disks, a SATA II disk and a SATAPI disk. A succinct and full listings of the sysfs tree are shown using the tree(1) program. Sample configuration -------------------- Directly attached devices, cascaded expanders and wide ports 1. SAS disk on HA phy 0, forming a narrow port, port 0. 2. Expander on HA phys 4, 5, 6, and 7, forming a wide port, port 1. 3. Port 0, narrow, of phy 0, is formed between the host adapter and a SAS end device with SAS port identifier (aua/aka, SAS address) 500000e000031c12. This device has a single LU, with LUN 0, which is a disk device. 4. Port 1, wide, of phys 4, 5, 6 and 7, is formed between the Host adapter's phys 4-7 and the expander with SAS address 50001c1716010600, Expander A. 5. Expander A, 50001c1716010600, has 4 devices attached to it: - An expander with SAS address 50001c1071609c00, expander B (using a 2 link wide port, see below). - A SATA II disk, 50001c1716010603, using the expanders' STP/SATA bridge. - An SES device, LUN 0 of 50001c171601060d. - And a SAS disk, LUN 0 of 5000c50000513329. 6. Expander B, 50001c1071609c00, has 3 devices attached to it: - A SATAPI device, 50001c1071609c02, using the expander's STP/SATA bridge. - A SAS disk, LUN 0 of 5000c50000102a65. - And an expander, 5005076a000001e0, expander C, (using a 2 link wide port, see below). 7. Expander C, 5005076a000001e0, has 3 devices attached to it: - A SAS disk, LUN 0 of 5000c50000513385. - An SES device, LUN 0 of 5005076a000001ed. - A SAS disk, LUN 0 of 5c50000000409c11.
