Note that the unit (“USED BY” column) will be assigned in the next subsection. Also,
the existing chunksize will be maintained in the new controller. The chunksize cannot be
changed because you cannot use the “initialize” command.
5.9.5 Recreate Units
Recreate the units recorded earlier in the Logical Unit Table (Table 5–1). Use the
add
unit
command once for each LUN entry in the table.
Example:
HSZ> add unit [
LUN] [uses]
If the unit in the previous example (from Table 5–1) is D300 the form of the command
line you would type is:
HSZ
>
add unit d300
r5
5.9.6 Enable Previous Options
View the units just created.
HSZ> show unit full
Compare all the parameters in this listing with the Logical Unit Table (Table 5–1).
Change the unit settings to be the same as those listed in the table using the
set
command where necessary.
The format of the
set
command for each item in the Logical Unit Table (Table 5–1) is
shown below for easy reference. Use only the entries that pertain your configuration.
RUN
HSZ> set [
LUN] run
HSZ> set [
LUN] norun
WRITE_PROTECT
HSZ> set [
LUN] write_protect
HSZ> set [
LUN] nowrite_protect
