Troubleshooting Your Installation
Media Install
Media Install
If your installation from the media fails, check the following:
1. If you are using a CD-ROM as a depot for updating or installing
software, ensure that the CD-ROM is mounted, using the mount
command, before you attempt to use it as a source.
2. Ensure that connections to drive(s) and I/O cards are secure. Remove
and replace cables or cards if a loose connection is suspected. You
would want to do this, for example, if the system is unable to contact
the drive.
3. If you forget to change source tapes, you may see the following error:
"loopback:/dev/rmt/0m": An I/O error occurred while performin
g this task.
The swinstall utility displays this message when it reads an install
tape that you have inadvertently left in the drive, and which does not
have any SD information on it.
Adjusting File System Size
If the required file-system size for the bundle you install exceeds that file
system limit set by your disk installation, you will get an error condition
during install. You can use lvextend and extendfs in this situation to
create a larger file system.
You might have a problem updating your system(s) if the /usr volume is
too small. The previous default size was 300 MB, and depending on
which bundle you are updating, you might require more.
If you try an update, swinstall will determine how much disk space is
required. If there isn't sufficient space, swinstall will report an error
like this:
ERROR: The used disk space on filesystem "/usr" is estimated
to increase by 57977 Kbytes.
This operation will exceed the minimum free space for this
volume. You should free up at least 10854 Kbytes to avoid
installing beyond this threshold of available
user disk space.
In this example, you would need to increase the file system size limit of
/usr by 10 MB, which actually needs to be rounded up to 12 MB.
