Setting up ACLs on VOBs after upgrading to 8.0.1
Complete administrative tasks required to enable ACLs on VOBs and ClearCase® clients upgraded to version 8.0.1. Start by reformatting VOBs into the new schema, if required. Then, define ACLs, test them out in a limited deployment, and finally enable them for users.
Before you begin
- Back up ClearCase
- Before upgrading, back up the ClearCase environment. For instructions, see Back up environment resources. During back up, make sure you save the vob_scrubber_params.template file if you have customized it. In ClearCase version 8.0.1, the template was updated to add support for new events. After upgrading to ClearCase 8.0.1, merge the customized content from the back up file into the new template.
- Check available disk space
- VOBs at schema 54 must be reformatted to schema 80 before you can enable ACLs on VOB objects.
Reformatting requires that the VOB storage database has enough free disk space to hold two copies of
the VOB database. Before upgrading, verify that the VOB has enough space for reformatting. To check
disk space, use the cleartool command
cleartool space -vob <vobtag>
and check the VOB database line. You can also generate a space report with this cleartool command:cleartool space -vob -generate
. Before reformatting, review VOB administration in the ClearCase Administration documentation and the reformatvob reference page. - Check VOB health
- For details, see Check VOB health before enabling ACLs.
About this task
- VOB format must be schema 80
- VOB feature level must be feature level 8.
- ACLs must be explicitly enabled on the VOB.
If a schema upgrade is required, the VOB must be offline during reformatting. After the reformat completes, you can return the VOB to service until you are ready to complete the process to enable and enforce ACLs.
You can upgrade ClearCase clients to version 8.0.1 and use them with ClearCase version 8.0 servers while you are working on the server upgrade. After a ClearCase server is upgraded to version 8.0.1 and actively enforcing ACLs, that server is only compatible with ClearCase client version 8.0.1 or later.
