V-5-1-5929
VxVM vxconfigd NOTICE V-5-1-5929 Unable to resolve duplicate diskid.
◆ Description: When VxVM detects disks with duplicate disk IDs (unique internal
identifiers), VxVM attempts to select the appropriate disk (using logic that is specific
to an array). If a disk can not be selected, VxVM does not import any of the duplicated
disks into a disk group. In the rare case when VxVM cannot make the choice, you
must choose which duplicate disk to use.
Note In releases prior to 3.5, VxVM selected the first disk that it found if the selection
process failed. FromVxVM 3.5 onward, the default behavior is to avoid the
selection of the wrong disk as this could lead to data corruption. Arrays with
mirroring capability in hardware are particularly susceptible to such data
corruption.
◆ Action: User intervention is required in the following cases:
◆ Case 1: When DMP is disabled to an array that has multiple paths, then each path
to the array is claimed as a unique disk.
If DMP is suppressed, VxVM does not know which path to select as the true path.
You must choose which path to use. Decide which path to exclude, and then
either edit the file /etc/vx/vxvm.exclude,or, if vxconfigd is running, select
item 1 (suppress all paths through a controller from VxVM’s
view) or item 2 (suppress a path from VxVM’s view) from vxdiskadm
option 17 (Prevent multipathing/Suppress devices from VxVM’s
view).
