Encrypted Volume and File System v1.1 Release Notes

• The Multi Volume File System feature of Veritas, which is not supported by EVFS.

• EVFS is currently available in English only.

Known Problems

Possible Device File Collision

NOTE: This problem has been fixed in HP 11i v3, and is only applicable to HP-UX 11i v2

Update 2.

(SR 8606459127) Executing the newfs or mkfs command for an EVFS volume can fail on systems

with components that call alloc_fake_device(), such as systems that are NFS clients. This

problem is caused by a defect in the alloc_fake_device() routine.

Symptoms

The newfs or mkfs command fails with a message similar to the following:

vxfs mkfs: /dev/evfs/vg01/relvol1 is mounted, cannot mkfs

The output from the lsdev command shows that the character major number used by the device

driver fake is the same as the block major number used by the device driver evfsevol. In the

example that follows, the common number is 2:

# lsdev

Character Block Driver Class

2 -1 fake pseudo

115 2 evfsevol pseudo

Workaround

The following workaround is only necessary and applicable to HP-UX 11i v2 Update 2.

Install patch PHKL_37146. You can download patches from the HP IT Resource Center at:

vxresize -F Can Cause Data Loss or Corruption

The vxresize –F command resizes a VxVM volume and the file system mounted on the

volume. The vxresize command has no knowledge of EVFS, so if you configure EVFS on a

VxVM volume and then execute the vxresize –F command, vxresize does not allocate space

for the EVFS data structure (the EMD) on the volume. The vxresize -F command completes,

but file operations might fail; data might be lost or corrupted.

Symptoms

The vxresize -F command completes, but file operations might fail; data might be lost or

corrupted.

Workaround

Resize the VxVM volume and file system in separate operations. Use the vxassist command

to increase or decrease the VxVM volume size (or the vxresize command without the –F

option). Use the extendfs or fsadm command to resize the file system.
