Known issues
%dirty may lag from actual percentage dirty for instant snap data cache object
(DCO) volumes. That is, the command output may show less %dirty than actual.
Encapsulation of a multi-pathed root disk fails if the dmpnode
name and any of its path names are not the same (2607706)
The encapsulation of a multi-pathed root disk fails if the dmpnode name and any
of its path name are not the same.
For example:
Dmpnode:sdh
Paths: sda sdb
Work-around:
Before running the encapsulation command (vxencap), run the following command:
# vxddladm assign names
Recovery and rollback to original configuration may not
succeed if the system reboots while the online migration setup
is in partial state (2611423)
During online migration from LVM to VxVM volumes, if there is a system reboot
when the migration setup is in partial state, that is, the start operation has not
completed successfully, then the recover and abort operations might not be able
to recover and rollback the configuration.
Workaround: This needs manual intervention for cleanup, depending on the state,
to restore the original configuration.
During online migration from LVM to VxVM volumes, LVM
sometimes incorrectly reports the remapped LVM device paths
as valid LVM volumes
Problem: In a migrated or committed configuration, only the renamed LVM names
of the form _vxlv are valid LVM volumes. The original LVM names,
in turn, point to target VxVM volumes. However, LVM sometimes incorrectly
reports these original LVM device paths pointing to VxVM volumes, as valid LVM
volumes.
Do not assume these as LVM volumes or do any operations on them, as it would
disrupt the application’s access to the target VxVM volumes.
