Problem (displayed message ID)

Cause

Actions

The status of the migration task is
Failure.
(KATS62010-E or KATS62011-
E

)

An error occurred during
migration. The details of the error
are displayed in the Task
Detailed Information-Task ID pop-
up window (11-2 Viewing
Detailed Information about a
Migration Task
).

Depending on the cause of the
error, migration may be treated as
a migration failure in Tiered
Storage Manager or Device
Manager, even though migration
has finished in the storage
subsystem.
Therefore, you need to refresh
the relevant storage domain by
using Tiered Storage Manager to
update the management
information of Tiered Storage
Manager and Device Manager to
the current information. If a
volume is left as reserved, it is
released during the refresh. After
that, view the volume information
of migration tasks that have a
failure status, and then, from the
elements listed below, determine
whether the migration task has
been executed. In this case,
check the following elements for
all logical devices (LDEV) in the
migration group:

Array group name

Subsystem name

If there is a logical device for
which migration has not been
executed, remove the cause of
the error, and then create and
execute the migration task again.

Some of the
LDEVs that
make up the
LUSE volume
are not
included in the
same storage
tier.

Situation (1)
The migration
volume pair
was created so
that LDEVs
other than the
representative
LDEV that do
not meet the
conditions of
the migration
destination
storage tier
would not be
migrated.

Both of the following conditions
exist:·

The representative LDEV is
included in the migration
destination storage tier.

LDEVs other than the
representative LDEV are not
included in the migration
destination storage tier.

Review the migration volume pair.
If you migrate LDEVs other than
the representative LDEV, first re-
specify the migration destination
volume, and then perform
migration.

Situation

(2)

The migration
volume pair
was created so
that LDEVs
that meet the
conditions of
the migration
destination
storage tier
would be
migrated
unnecessarily.

Both of the following conditions
exist:·

The representative LDEV is
not included in the migration
destination storage tier.

LDEVs other than the
representative LDEV are
included in the migration
destination storage tier.

Review the migration volume pair.
Create a storage tier that includes
the representative LDEV, and the
status will change to situation (1).
See the recommended action
column for situation (1) and take
appropriate action.
