Q1 . Is there a possibility to exclude the logvolume?
There are two log volumes,
1. One is archive log location which is not part of IntelliSnap backup and this location should point to disk location, you can change this location if it is pointing IntelliSnap volumes
Please follow following BOL section for changing location
(Modifying the DB2 Archive Path, Modifying the DB2 Audit Error Path and Modifying the DB2 Retrieve Path) please make sure new location should have 777 permissions http://documentation.commvault.com/commvault/v11/article?p=14873.htm
2. one is active log location which carries db2 active logs, this active log location is part of IntelliSnap backup, you can check this location in db2 database configuration parameter called “Path to log files”
Q2. Is there a possibility to include other volumes?
Yes you can add as many as you want to add SNAP volumes in DB2 database, this is done by db2 not from Commvault
Commvault take IntelliSnap backup for all the volumes that include the path listed in db2 SQL query "select dbpartitionnum, type, path from sysibmadm.dbpaths" for each database partition.
