Addressing a StorEdge A5000 Disk Array

You can address a StorEdge A5000 disk array by path name or enclosure name.

Specifying the Path Name

You can specify the device or controller using either a complete physical path name or a complete logical path name. A typical physical path name for a StorEdge A5000 disk array is:

---

/devices/sbus@1f,0/SUNW,socal@1,0/sf@0,0/ssd@w2200002037000f96,0:a,raw

---

or

---

/devices/io-unit@f,e0200000/sbi@0,0/SUNW,socal@2,0/sf@0,0/ssd@34,0:a,raw

---

For all StorEdge A5000 disk array interface boards (IBs) on the system, a logical link to the physical paths is kept in the directory /dev/es. An example of a logical link is /dev/es/ses0.

Specifying the Enclosure Name

For the StorEdge A5000 disk array, you can select a device or interface board using the world wide name (WWN) instead of the path name. The WWN is a unique 16-digit hexadecimal value that specifies either the port used to access the device or the device itself. A typical WWN value is 2200002037000f96.

You can also specify the name of the StorEdge A5000 disk array and an identifier for the particular device in the enclosure. A device in a StorEdge A5000 disk array is identified as follows:

---

BOX_NAME,[f|r]slot_number 

---

where:

Table 1-1 Addressing a StorEdge A5000 Disk Array by Enclosure Name

Options/Arguments	Description
BOX_NAME	is the name of the StorEdge A5000 enclosure, as specified by the enclosure_name subcommand
f or r	specifies the front or rear slots in the StorEdge A5000 enclosure
slot_number	is the slot number in the StorEdge A5000 enclosure, either 0-6 or 0-10

When addressing the StorEdge A5000 disk array, the path name or enclosure name specifies the StorEdge A5000 IB.
