Explanation
When you add a managed MDisk to a storage pool,
the new MDisk is validated to ensure that adding it to the storage
pool will not adversely impact the storage pool status. Either the
current status of the MDisk has not allowed the validation to be performed,
or the validation has failed. Note: You cannot add Read Only or faulty
MDisks to a storage pool.
User Response
- If the MDisk identity has changed since it was last discovered,
submit the command-line interface command detectmdisk,
which might correct the problem.
- Check switch zoning and logical unit presentation on the controller
to ensure that the MDisk is physically and logically connected to
all of the nodes in this cluster.
- Ensure that the controller settings are correct and that the MDisk
logical unit is correctly configured.
- Ensure that the MDisk logical unit state is one that passes the
validation. A Read Only or faulty MDisk fails the validation.
- View the cluster event log for more information about the failed
validation.
