Features nearing End of Support
• VxFS 5.1 SP1 does not support creating or mounting file systems using DLV 3 or lower. HP
recommends that you upgrade all older disk layouts to Version 7.
• Future major releases of VxFS may discontinue support for DLV 5.
• The nau, ausize, aufirst, aupad and ninode options to the mkfs command are not
supported. The mkfs command accepts these options but ignores them without a warning.
These options can be omitted from the mkfs command in future releases.
• The default version for the File Change Log (FCL) in VxFS 5.1 SP1 is version 4. VxFS 5.1 SP1
is the last major release to support FCL version 3. Upgrade FCL to version 4 to make use of
the advanced logging facilities provided by Version 4 and for facilitating future upgrades.
• The fscdstask command, used for performing online Cross-Platform Data Sharing (CDS)
operations, has been replaced by the fscdsadm command. Support for the fscdstask
command might be dropped in future VxFS releases.
• The functionality provided by the Veritas multi-volume support feature replaces most of the
functionality provided by the Quicklog feature.
• The snapshot feature may not be available in future Veritas releases.
