The following message may be displayed:
The Solaris operating environment on slice c0t0d0s0 cannot be upgraded.A file system listed in the file system table (vfstab) could not be mounted.
The installation software may interpret inodes that are stored on striped DiskSuiteTM meta devices for root inodes and attempt to mount the meta devices as upgradable slices. When this problem occurs, the mounts fail and the installation aborts.

An upgrade to TotalNET Advanced Server (SunLinkTM) version 5.2 is required with the Solaris 7 operating environment because of a driver conflict. Version 5.0 and version 5.1 for the TotalNET Advanced Server cause the Solaris 7 operating environment to not boot correctly.
Workaround: Before you install the Solaris 7 operating environment, you must upgrade all installations to version 5.2 for the TotalNET Advanced Server, which is available on the Solaris Easy Access Server 2.0 CD. Follow the instructions provided to upgrade existing TotalNET Advanced Server installations.
Be sure to read bug description ID 4121281 before you start upgrading your x86 based system to the Solaris 7 8/99 operating environment.
If you are running DiskSuiteTM and upgrading to Solaris 7, you must also upgrade to DiskSuite 4.2. The DiskSuite 4.2 distribution includes a script called metacvt that automates removal and replacement of the metadb replicas. You can use that script to change the SCSI driver name stored in the replicas from cmdk to sd when you upgrade to Solaris 7 and DiskSuite 4.2.
Workaround: To avoid potential data loss during upgrades to the Solaris 7 operating environment, you must save the system's meta device configurations in text files and remove their metadb replicas before upgrading any x86 based system that is running DiskSuite. After you finish upgrading your x86 based system, you must restore the meta device configurations by using the DiskSuite command line interface.
The DiskSuite Version 4.2 Release Notes contain a procedure for saving metadb configurations, removing metadb replicas, upgrading x86 based systems to the Solaris 7 operating environment, upgrading DiskSuite to version 4.2, and restoring meta device configurations. Bourne shell scripts that automate the procedure are available for the Solaris 7 operating environment.
This appears as an attempt to install the same architecture and version of a package that is already installed. This installation overwrites this package.
The "Installing Solaris Software - Progress" bar sometimes indicates that an installation is complete when it is still in progress. The install program may add packages for several minutes after the progress bar has indicated that the installation is complete. Do not rely on the progress bar to indicate that the installation is complete. The installation displays the following message when the program has completed all installation operations:
When you upgrade the Solaris operating environment on a server with diskless clients, the options on the dfstab line are not preserved for /usr. For example, if you entered the following in the dfstab file:
share -F nfs -o rw /export/exec/Solaris_2.7_sparc.all/usr
then this entry is automatically replaced with the following entry during the upgrade:
share -F nfs -o ro /export/exec/Solaris_2.7_sparc.all/usr
Workaround: Before you attempt to upgrade the Solaris operating environment on an OS server that has a diskless client or Solstice AutoClient, back up the /etc/dfs/dfstab file for the clients.
Be sure to read bug description ID 4121281 mentioned in"Installation Bugs That Occur Before the Start of an Interactive Installation" earlier in this chapter as well as any other bug description listed in this section before you start upgrading your x86 based system to the Solaris 7 8/99 operating environment. This problem may cause data loss.
