Nondisk Device Names

The syntax for a file name that identifies a nondisk device is:

node

specifies the name of the node on which the device resides. A node name

consists of a backslash (\) followed by one to seven alphanumeric characters; the

first alphanumeric character must be a letter.

device-name

specifies the name of a device. A device name consists of a dollar sign ($)

followed by one to seven alphanumeric characters; the first alphanumeric

character must be a letter.

qualifier

is an optional qualifier. It consists of a pound sign (#) followed by one to seven

alphanumeric characters; the first alphanumeric character must be a letter.

ldev-number

specifies a logical device number. A logical device number is represented by a

dollar sign ($) followed by a maximum of five digits. The logical device number 0

(represented “$0”) is reserved for the Event Management Service (EMS) collector

process.

It is recommended that, wherever possible, the

device-name form of a nondisk

device name be used instead of the

ldev-number form. This is especially true

when referring to devices that are dynamically configured.
