Encrypted Volume and File System v1.1.2 Release Notes

Ignite-UX will read these files in cleartext. If the output media is not an EVFS volume, such
as a tape, Ignite-UX will store these files in cleartext.
• Executing the command vxresize with the -F option can cause lost or corrupt data. For
more information and a workaround, see “vxresize -F Can Cause Data Loss or Corruption”
(page 11).
• Renaming VxVM volumes with EVFS enabled makes the volume unusable. For more
information and a workaround, see “Renaming VxVM Volumes with EVFS Enabled Makes
the Volume Unusable” (page 12).
• EVFS is not supported by SAM or SMH.
• The evfsadm trace command is intended for use by support personnel only. HP does
not support this feature on customer environments.
• During inline encryption, the volume is not accessible until the entire operation is completed.
• The Multi Volume File System feature of Veritas, which is not supported by EVFS.
• EVFS is currently available in English only.
• Keys limit: 4096 per key type for private, public, and AES keys.
• Volume limit: 1023 encrypted volumes per system.
• ServiceGuard version A.11.18 or later using modular packages supports EVFS volumes
without a file system.
• EVFS is not supported with ServiceGuard/SGeRAC shared activation.
• The following features on ServiceGuard version A.11.19 are not supported by EVFS:
— Online package configuration
— Partial-startup maintenance mode
• When a device is used for EVFS, writing to a non-EVFS device (for example,
/dev/vg00/lvol1) instead of the EVFS device (for example, /dev/evfs/vg00/lvol1)
will cause data corruption.
• Because of the computing intensive nature of the encryption algorithms, HP recommends
at least one additional CPU when using EVFS software.
