Error description
Tivoli Storage FlashCopy Managercan mistake similarly named filesystems as nested filesystems when in fact the filesystem is not nested. For example: FlashCopy Manager for Custom Applications will determine that '/abc/prd' is the root directory of 'abd/prddr'. Initial Impact: Medium Tivoli Storage Manager Versions Affected: FlashCopy Manager for Custom Applications v2.2 on AIX, Solaris, and Linux FlashCopy Manager for DB2 v2.1 & 2.2 FlashCopy Manager for Oracle v2.1 & 2.2 FlashCopy Manager for Oracle in SAP environments v2.1 & 2.2 Additional Keywords: nested
Local fix
Change the filesystem named /abc/prd to /abc/prod or /abc/prd_ or anything else that differentiates 'prd' from 'prddb'.
Problem summary
**************************************************************** * USERS AFFECTED: Users of one or more IBM Tivoli Storage * * FlashCopy Manager 2.1.x and 2.2.x on AIX, * * Solaris, and Linux, components listed below * * that have similarly named file systems: * * FlashCopy Manager for Custom Applications * * FlashCopy Manager for DB2 * * FlashCopy Manager for Oracle * * FlashCopy Manager for Oracle in SAP * * environments * **************************************************************** * PROBLEM DESCRIPTION: Tivoli Storage FlashCopy Manager can * * mistake file systems as nested file * * systems when the name of a files system * * is a substring of another file system * * name. * * * * For example: FlashCopy Manager for * * Custom Applications will * * determine that '/abc/prd' is the root * * directory of 'abc/prddr'. * **************************************************************** * RECOMMENDATION: * **************************************************************** Similarly named file systems detected as nested file systems when in fact the file system is not nested.
Problem conclusion
IBM Tivoli Storage FlashCopy Manager is corrected to correctly determine nested mount points. Please keep in mind that nested mount points remain being unsupported with IBM Tivoli Storage FlashCopy Manager for the 2.1 and 2.2 releases. Nested mount points are only supported with the 3.1 and later releases. This fix only prevents the program from falsely diagnosing nested mount points.
Temporary fix
Avoid using file system names that are substrings of another file system name.
