Chapter 6 First-Time Configuration 6-19
6.1.11 Deleting Logical Drives
To assign a different RAID level or a different set of drives to a logical drive, you
must unmap and delete the logical drive, and then create a new logical drive.
Deleting logical drives is an optional operation when configuring a Sun StorEdge
3510 FC array. However, with the Sun StorEdge 3511 FC array, deleting logical drives
is required so you can create logical drives that support redundancy.
Caution – This operation erases all data on the logical drive. Therefore, if any data
exists on the logical drive, it must be copied to another location before deleting the
current logical drive.
Note – You can delete a logical drive only if it has first been unmapped.
To first unmap and then delete a logical drive, perform the following steps:
1. From the Main Menu, choose “view and edit Host luns.”
A window displays a list of channel and host IDS.
2. Choose a channel and host ID combination from the list and press Return.
A list of host LUNs that are assigned to the selected channel/host combination is
displayed.
3. Select a host LUN from the displayed list and press Return.
A confirmation message asks if you want to unmap the host LUN you have selected.
4. Choose Yes to unmap the host LUN from the channel/host ID.
5. Repeat Step 3 and Step 4 to unmap all remaining host LUNs that are mapped to
the logical drive you want to delete.
6. Press Escape to return to the Main Menu.
