Table 5-1: Troubleshooting (Continued)
Symptom
Before you perform an array migration,
you may want to test the new target array
by writing data to it. When you write data
to the array, the array's migration guard
becomes enabled automatically. This
safety feature prevents an array that
contains data from being overwritten.
Therefore, to use an array with data as a
target array in a data migration operation,
you must first release the migration guard
using the suggested actions to the right to
allow the data on that array to be
overwritten.
1. Move the MAIN SW switch on the back panel of the
source array to the OFF position. Verify that the
POWER LED goes OFF.
2. Move the MAIN SW switch on the back panel of the
target array to the OFF position. Verify that the EXT
and POWER LEDs go OFF.
3. Remove the migration cable between the source and
target arrays.
4. Connect your storage network to the management
port on the target array.
5. On the target array, set the MODE switch to N.
6. Move the MAIN SW switch on the back panel of the
source array to the ON position. Verify that the
POWER LED goes ON and that the READY LED goes
ON in a few minutes.
7. Log in to Storage Navigator Modular 2.
8. In the Arrays area, click the Add Array button and
add the array to the Storage Navigator Modular 2
database.
9. Go to Settings > Replacement of Array and select
Check for New Array.
10. A status of Guarded means the release migration
guard is enabled. To disable the migration guard, click
Release Migration Guard in the Migration Guard
Setting to acknowledge that the array can be
overwritten. A confirmation dialog box appears.
11. Click the checkbox, then click OK to continue.
12. Move the MAIN SW switch on the back panel of the
target array to the OFF position. Verify that the
POWER LED goes OFF.
13. Remove the cable from the management port of the
target array.
14. Return the MODE switch on the target array to the E
position.
15. Connect the auto migration cables to the source and
target arrays.
16. Move the MAIN SW switch on the back panel of the
target array to the ON position. Verify that the EXT
and POWER LEDs go ON.
17. Move the MAIN SW switch on the back panel of the
source array to the ON position. Verify that the
POWER LED goes ON and that the READY LED goes
ON in a few minutes.
18. Perform the auto migration operation described in the
Hitachi Simple Modular Storage 100 Auto Migration
Assistant Guide (MK-97DF8066).
