/etc/conf/cf.d/change_ha
You must log in as root to execute the script.
The change-ha script has no options.

/etc/con/cf.d/mscsi
/etc/conf/sdevice.df ad
/etc/conf/sdevice.d/eiad
The change-ha script displays a table that shows the SCSI host
adapters to which particular SCSI devices are attached. It also
asks if you want to change the host adapter prefix to identify a
different host adapter with a device. If you change the host
adapter prefix, change-ha writes this new information to the
mscsi file that the system uses for configuration information.
Normally, this script is executed as part of the UNIX SCSI Manager
installation procedure. You can invoke the change-ha script
separately if you need to modify the configuration after
completing the installation. You must relink the kernel after
executing change-ha to effect your changes.
If you configure two host adapters of the same type and then
remove the adapter that has a SCSI ID of 0, change-ha
automatically renumbers the second adapter’s ID from 1 to 0 and
updates the appropriate files in the /etc/conf/sdevice.d directory.
Change-ha supports two host adapters, identified by prefix in the
following table:
Prefix Adapter board
ad
eiad
SCSI host adapter-Standard mode
SCSI host adapter-Enhanced mode
