AIX Configuration
During power-up initialization, AIX will find and configure the
new adapter(s) and any supported devices using the driver's
configuration method. Devices are assigned a SCSI ID as they
are discovered starting with 0. SCSI ID is not related to loop
ID, port ID or to SCSI ID assignment on other hosts. It is a
logical value bound to the fibre channel WWN of the device.
Configuration may also be run from the command line:
cfgmgr
Once disks have been configured, the standard AIX utilities
may be used to build volume groups, logical volumes and file
systems. See the
AIX System Management Guide
for a detailed
explanation.
Find out the names of the installed adapters with the command:
lsdev -Cc adapter
In arbitrated loop, the ID of each device must be unique. For
disk drives, the ID is typically set by switches on the drive
enclosure. The adapter ID is soft assigned and may be
examined after it is participating with the
mbtest
command. If
the adapter name found by the
lsdev
command were
fscsi1
, the
command would be:
/usr/lpp/cbxfc/mbtest fscsi1 id
The requested ID may be changed in the database to any non-
conflicting value in the range 0 to 126 with the command:
chdev -l fscsi1 -a id=6 –P
The ID attribute has no effect in a fabric environment.
