Working with Controllers
If the CLI encounters a problem during these integrity checks, it
issues an error and does not continue the flash update.
Understanding Channel Attributes
A channel is a path used for transferring and controlling data
between a storage controller and storage devices. SCSI devices
present on a controller are identified by a combination of their
channel number, SCSI device ID (also known as the target ID), and
Logical Unit Number. The SCSI device name is represented as
(CHANNEL:ID:LUN) in this user guide. An example SCSI device
name is (2,03,1).
Channel attributes are characteristics of a channel that you can
administer or display using the CLI. Table 3-2 lists the channel
attributes and their related CLI commands:
