Partitioning an Existing Logical Drive or Logical Volume/Creating a
Partition
NOTE: Before you can create a partition,
you must unmap all assigned LUNs.
- Select the array that contains the logical
drive(s) you want to partition.
- View the logical drives or logical volumes
you want to create partitions on.
- If any of these logical drives or logical
volumes have host LUN assignments, proceed to Step 4; if they do not,
proceed to Step 8.
- Choose Configuration > Custom Configuration.
- Select Change Host LUN Assignments.
- Select the Host LUN(s) that are attached
to the logical drives or logical volumes you want to partition, and
click Unmap Host LUN.
- Click OK, and then click Close.
- Choose Configuration > Custom Configure.
- Select Manage Existing LDs/LVs and
Partitions from the Custom Configuration Options window.
- Select the Partitions tab.
- Select a logical drive or logical volume
you want to partition.
- Specify the Partition Size in Mbyte,
and click Create.
To create multiple partitions of the same
size, click Add Partition as many times as partitions you want
to create. You can also type the partition size in the Part Size
field and multiply (*) it by the number of partitions you want to create,
for example 100*128. Any remaining Mbyte is added to the last partition.
As you add partitions, the remaining capacity
displayed in Available Size (MB) decreases by the amount of the
partition size.
- To change the size of a partition you
have already created, select the logical drive or logical volume, and
click Modify Size.
- Specify the new size (in Mbyte) in the
Partition Size field, and click OK.
- Click OK in the Confirm Configuration
Operation to complete the operation, and click Close.
After a logical drive or logical volume has been partitioned, when you
open a logical drive or logical volume on the main window, the partitions
are displayed.
- (HP-UX OS only). To ensure that the environment
is stable and accurate after making configuration changes, you must
run the ioscan -fnC
disk command.
NOTE: If you used System Administrator Manager (SAM) to unmount
the file system, make sure it is closed before running the ioscan command.
- (IBM AIX OS only). To ensure that the
environment is stable and accurate after making configuration changes,
you must update the Object Data Manager (ODM) as explained in Updating
the Object Data Manager on an IBM AIX host.
The Logical Drive/Logical Volume Number
For important information regarding the logical
drive number displayed in the LD field in the Manage Existing
LDs/LVs and Partitions window, see The
Logical Drive/Logical Volume Number.
