Upgrading the system
Comparing directory and file permissions
After you activate the new system, you should verify that the directories and files copied over from the old system retain the same permissions, or that the new permissions are acceptable. The system can compare the permissions of the directories and files.
Because comparing the file permissions may take a long time (30 minutes or more), you may want to run this command in the background so you can continue with other CVUE upgrade procedures.
To compare directory and file permissions:
1.Enter:
cd /cdrom/cdrom0
2.Enter:
./verify_fileproperties
To run this command in the background, enter:
nohup ./verify_fileproperties /nohup.out&
This begins the comparison of the directory and file permissions.
3.After the command is finished, the system displays the following message:
See /var/log/cvue_file_diff for differences
#
4.To view the permission differences after the command is finished, enter: pg /var/log/cvue_file_diff
The file permission differences are displayed. If any file permissions are not appropriate, correct those discrepancies. Any files that are found only on the new system are identified as such and should not be changed.
5.To check the progress of the comparison command while it is still executing, enter: tail
Messages display directory and file permission differences as they are found. Press Del to break out of viewing the file.
6.Continue with Updating the switch setup.
