Set up the Fibre Channel switches.
For details on how to set up a Fibre Channel switch, see the

Set up the HBA.
For details on how to set up an HBA, see the documentation for the HBA.
Make sure that all HBAs that are on a single host and connected to HDLM-
managed disks are of the same type and have the same microprogram
version. If you are using more than one type of HBA, paths will not be
able to be switched when an error occurs. Set the SCSI target ID
according to the HBA settings. For details on checking the target ID, see
the HBA documentation.

Make sure the OS recognizes the LU.
Execute the cfgmgr command to configure the device, and then execute
the lsdev command to make sure that the physical volume has been
recognized as hdisk.
# cfgmgr
# lsdev -Cc disk
Switch the Kernel Mode
Before installing HDLM, decide which kernel mode you will use to operate
AIX, and change to the desired kernel mode if necessary.
The following shows how to switch the kernel mode.
1
.
Check the kernel mode currently being used.
Execute the following command.
# bootinfo -K
32 will be displayed when the 32-bit kernel is being used, and 64 will be
displayed when the 64-bit kernel is being used.
2
.
Switch the kernel mode.
When AIX is running, change the symbolic link for /usr/lib/boot/unix
and /unix to switch the current kernel mode to the desired mode.
¢
The path for the 64-bit kernel mode
/usr/lib/boot/unix_64
¢
The path for the 32-bit kernel mode
/usr/lib/boot/unix_up (for a uni-processor)
/usr/lib/boot/unix_mp (for a multi-processor)

.
Execute the bosboot command.
# bosboot -ad /dev/ipldevice
