c. Run the following script to deconfigure AP (and save the AP configuration so
that it can be restored later):
This script saves the current AP configuration information in the files
/var/tmp/ap*
. This script also generates executable shell scripts that you can
use to regenerate your AP configuration. You may examine the
/var/tmp/ap*
files if you wish, but do not modify or remove them. Doing so can compromise
the upgrade procedure.
d. If any file systems shown in
/etc/vfstab
are still configured as metadevices,
edit
/etc/vfstab
and reconfigure those file systems as physical devices.
Caution –
You must be a knowledgeable system administrator to edit
/etc/vfstab
. If you do not configure your file systems properly in
/etc/vfstab
,
it is possible that you will lose data the next time you boot the server.
e. Remove the packages
SUNWapdoc
,
SUNWapr
,
SUNWapu
, and
SUNWabap
by using
the
pkgrm(1M)
command.
6. If you plan to upgrade to the Solaris 7 11/99 operating environment, perform that
upgrade now.
See “Upgrading a System” in Solaris 7 (SPARC Platform Edition) Installation Library.
Note that you must choose the upgrade option to perform an upgrade of the Solaris
software.
Caution –
Wait until the Solaris upgrade process is completely finished before
continuing with this procedure.
Caution –
Make sure you upgrade the correct slice. If you were previously using a
volume manager to mirror the boot disk, and if you were also using AP to
alternately path each boot disk mirror, then there are four physical paths that were
previously potential paths to the boot disk (two alternate paths for each boot disk
mirror). Now that both AP and the volume manager have been deconfigured,
examine
/etc/vfstab
to determine the physical path that corresponds to the root
(
/
) file system. When you run
suninstall
, specify that path as the disk to upgrade.
Later, when you restore your volume manager, be sure to designate that disk as the
primary mirror. See your volume manager documentation for information on
determining which physical slice is used when booting.
