)
An error occurred during data
erasure. The details of this error
are displayed in the Task
Detailed Information-Task ID pop-
up window (for details on this
window, see 11-2 Viewing
Detailed Information about a
Migration Task). Migration has finished. The
LDEVs of the migration source
volume and the migration target
volume have been switched.
Check the status of the source
volume whose LDEV has been
switched to the LDEV number of
the target volume. If data erasure
fails, the original data remains in
the source volume. (For details,
see Figure 12-1 Relationship
between Volumes and LDEV
Numbers 1-3 How Migration
Works) Therefore, perform the
following action:
If the Volume to which the LDEV
number of the source volume has
been switched is blocked
Format the relevant volume by
using Remote Web Console.
If the Volume to which the LDEV
number of the source volume has
been switched is not blocked
There may be data remaining on
the relevant volume. If the
remaining data needs to be
erased, format the volume or
erase the data using the
procedures below. In the
explanation below logical device
number 10:01 has been
migrated to 20:01 (the source
volume before migration has
been switched to 20:01 after
migration).
1 Use Device Manager to set
the path to 20:01 and
allocate it to a host.
2 From the path-allocated host,
write as much 0 data as the
volume size to erase data on
20:01.
3 Use Device Manager to
release the path to 20:01.
