Addressing

This section explains how to specify, or address, a disk array.

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

/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.

Addressing a SPARCstorage Array

When addressing the SPARCstorage Array, the path name specifies the SPARCstorage Array controller or a disk in the SPARCstorage Array. The controller name is specified by its physical name. for example:

/devices/.../.../SUNW,soc@3,0/SUNW,pln@axxxxxxx,xxxxxxxx:ctlr

The controller name can also be specified by a name of the form cN, where N is the logical controller number. luxadm uses the cN name to find an entry in the /dev/rdsk directory of a disk that is attached to the SPARCstorage Array controller. The /dev/rdsk entry is then used to determine the physical name of the SPARCstorage Array controller.

A disk in the SPARCstorage Array is specified by its logical or physical device name. For example:

/dev/rdsk/c1t0d0s2

/devices/.../.../SUNW,soc@3,0/SUNW,pln@axxxxxxx,xxxxxxxx/ssd@0,0:c,raw

See the disks(1M) and devlinks(1M) man pages for more information on logical names for disks and subsystems.

Addressing a SPARCstorage RSM Tray

When addressing the SPARCstorage RSM tray, the path name specifies the controller or a disk in the SPARCstorage RSM tray. The controller name is specified by its physical name. For example

/devices/sbus@1f,0/QLGC,isp@1,10000/sd@8,0:c,raw

A disk in the SPARCstorage RSM tray is specified by its logical or physical device name. For example:

/dev/rdsk/c2t8d0s2

See the disks(1M) and devlinks(1M) man pages for more information on logical names for disks and subsystems.
