The upgrade option is not presented even though there is a version of Solaris software that's upgradable on the system.Cause:
Reason 1: The /var/sadm directory is a symlink or it is mounted from another file system.Solution:
Reason 1: Move the /var/sadm directory into the root (/) or /var file system.Cause:
Reason 2: The /var/sadm/softinfo/INST_RELEASE file is missing.Solution:
Reason 2: Create a new INST_RELEASE file by using the following template:
OS=Solaris VERSION=x REV=0
Is the version of Solaris software on the system
Reason 3: SUNWusr is missing from /var/sadm/softinfo.Solution:
Solution 3: You need to do an initial installation. The Solaris software is not upgradable.
Couldn't shut down or initialize the md driverSolution:
Follow these instructions:
If the file system is not a RAID-1 volume, comment out in the vsftab file.
If the file system is a RAID-1 volume, break the mirror and reinstall. For information about unmirroring, see Removing RAID-1 Volumes (Unmirroring) in Solaris Volume Manager Administration Guide.
The upgrade fails because the Solaris installation program cannot mount a file system.Cause:
During an upgrade, the script attempts to mount all the file systems that are listed in the system's /etc/vfstab file on the root (/) file system that is being upgraded. If the installation script cannot mount a file system, it fails and exits.Solution:
Ensure that all file systems in the system's /etc/vfstab file can be mounted. Comment out any file systems in the /etc/vfstab file that cannot be mounted or that might cause the problem so that the Solaris installation program does not try to mount them during the upgrade. Any system-based file systems that contain software to be upgraded (for example, /usr) cannot be commented out.
The upgrade failsDescription:
The system does not have enough space for the upgrade.Cause:
Check Upgrading With Disk Space Reallocation for the space problem and see if you can fix it without using auto-layout to reallocate space.
