74 Managing logical disks (LUNs)
The Expand Logical Disk dialog box ( Figure 56 ) opens.
Figure 56 Expand Logical Disk dialog box
2. If more than one logical disk is listed, select the logical disk you want to expand from the list. The
Current Size (GB) text box shows the selected logical disk’s size.
3. In the Expand size by box, enter the amount to expand the logical disk either by clicking the up arrow
or typing the number.
4. Select the size unit by selecting either MB or GB from the list.
NOTE: The expand functionality is not supported on remote servers running Linux.
5. Click Expand Logical Disk.
6. To expand additional logical disks, repeat steps 2 through 5.
NOTE: For some storage subsystems, the logical disk expansion request returns immediately;
however the actual expansion process takes much longer to complete. While the expansion is in
progress, the subsystem rejects any new request to expand the logical disk. To determine if the
expanded logical disk status is rebuilding, click the Refresh the Storage Subsystem command on the
Advanced Operations menu.
7. When you are finished expanding logical disks, click Close.
NOTE: Logical disk (LUN) expansion is a direct request to the subsystem to expand the logical disk size
using unused space. The servers that have access to this logical disk might not recognize the new space for
the disk until the server is rebooted or some software is invoked to discover the new size. In Windows, for
example, you can use the Diskpart command-line utility to extend the volume to the newly-added space. In
Linux, you can use the lvextend command to extend the size of a logical volume.
Deleting a logical disk
Simple SAN Connection Manager provides an easy way to delete logical disks from your SAN.
