Encrypted Volume and File System v1.1 Release Notes

Renaming VxVM Volumes with EVFS Enabled Makes the Volume Unusable
The vxedit rename command renames a VxVM volume. The vxedit rename command has
no knowledge of EVFS, so if you have a VxVM volume with EVFS enabled and then rename the
volume, the mapping between the VxVM volume becomes unusable. EVFS commands fail.
Symptoms
The vxedit rename command will complete, but subsequent EVFS operations fail.
Workaround
Disable EVFS and unmap the EVFS volume before renaming the underlying VxVM volume.
After you rename the VxVM volume, you must map the new VxVM volume name to EVFS and
enable the new EVFS volume.
Compatibility and Installation Requirements
This section describes the compatibility information and installation requirements for this release.
For specific compatibility and installation information, see Encrypted Volume and File System v1.1
Administrator's Guide.
Software Compatibility
Software used with EVFS can be categorized into three types:
• Type 1 Software: Applications without kernel components. EVFS supports Type 1 Software.
Examples of Type 1 software include FTP, rcp, CIFS Server, and Oracle® Database 10g.
(This list is not exhaustive and is included only to provide examples of Type 1 Software.)
• Type 2 Software: Software with kernel modules that access the file system (Virtual File
System, VFS, or HFS or VxFS). EVFS supports Type 2 Software. The NFS server daemon is
an example of Type 2 software.
• Type 3 Software: Software with kernel components that directly access physical volumes
and implement file system or volume management functionality. EVFS does not supprt
Type 3 Software. Examples of Type 3 software include Oracle Automatic Storage Management
(ASM), and file systems other than HFS and VxFS, such as Veritas Cluster File System (CFS)
and Clearcase Multiversion File System (MVFS). (This is not an exhaustive list and is included
only to provide examples of the types of Type 3 Software.)
