EVFS prevents anyone who gains unauthorized physical access to storage media from reading or using the data.
automatically retrieve stored passphrases and use the passphrases to execute EVFS commands. CAUTION: Stored passphrases provide convenience, but they are security risks. New and Changed Features in this Release HP-UX EVFS version 1.1.1 (A.01.01.01) includes the defect fixes listed in “Defects Fixed in this Release” (page 6).

EVFS Does Not Support Persistent Device File Names Defect Number Description QXCR1000834171 EVFS does not support HP-UX 11i v3 persistent device file names. Symptoms The evfsadm map command does not support persistent device file names for disk devices and returns an error similar to the following: evfsadm: map error: invalid volume block device "/dev/disk/disk17" Workaround On systems without EVFS version 1.1.
EVFS cannot decrypt the kernel or other data before the system boots. CAUTION: Encrypting the boot disk can cause the boot disk to become unusable and prevent you from booting the system. — — Dump devices. Swap space (swap devices or file swap space). CAUTION: • Encrypting swap space can cause the system to panic. EVFS does not automatically convert existing volume data to encrypted data. To encrypt existing volume data, use the inline encryption feature in this release of EVFS.
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 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.
