PLEASE READ THIS NOTE CAREFULLY IF YOU INTEND TO PERFORM A NON-DESTRUCTIVE UPGRADE FROM SCO UnixWare 2.0.x to 2.1.x
This document was included in the SCO UnixWare Upgrade Kit SV507058 (if purchased from Fujitsu Computers Ltd.).
Prior to the upgrade, the system should be powered down (init 0) and all non-system disks should be removed as described above in the Mylex section (First Alternative).
After the upgrade the system should be powered down and the disks replaced.
Systems with a single SCSI channel need no special attention.
If a server is configured with an SMC ethernet adapter, the driver version must be 2.0.3 or later.
It is probable that the driver version would have been correct at UnixWare 2.0.x, but it is possible to unwittingly regress the driver during a non-destructive upgrade.
Given that v2.0.3 (or later) of the SMC ethernet driver was correctly installed prior to the upgrade, the problem can arise if the SCO nics package is installed when prompted during the upgrade. This package contains an older version of the SMC driver.
However, if you use the pkginfo command post-upgrade to check the version of the installed driver, this will still show v2.03. The only way of determining the actual version of the installed driver is to use the strings command on the file /etc/conf/pack.d/smpw0/Driver.o
This will yield:
if correct, and:
Provided that the instructions in the installation guide are followed, then the problem will not arise.
Please note that, even if the Combine System Files option is chosen for the upgrade, that the etc/profile file is not carried forward. To overcome this problem, you will need to create a tape backup of this file prior to the upgrade, and to reinstate it afterwards.
It is the responsibility of the system integrator to ensure that the user's application programs are certified for use with the target version of SCO UnixWare. We regret that we are unable to offer advice on this.
