Virtual Disk Task: Reconfigure (Step 1 of 3)

Does my controller support this feature? See "Supported Features."
The Reconfigure task enables you to change the virtual disk configuration. Using this task, you can change the RAID level and increase the virtual disk size by
adding physical disks. On some controllers, you can also remove physical disks.
Before continuing with the virtual disk reconfiguration, you should be familiar with the information in "Starting and Target RAID Levels for Virtual Disk
Reconfiguration and Capacity Expansion" and "Choosing RAID Levels and Concatenation."

To Reconfigure a Virtual Disk: Step 1 of 3

1. Select the physical disks that you want to include in the virtual disk. You can expand the virtual disk's capacity by adding additional physical disks. On
some controllers, you can also remove physical disks.
The changes you make to the physical disk selection are displayed in the Selected Physical Disks table.

2. Click Continue to go to the next screen or Exit Wizard if you want to cancel.

To locate this task in Storage Management:

1. Expand the Storage tree object to display the controller objects.

2. Expand a controller object.

3. Select the Virtual Disks object.

4. Select Reconfigure from the Available Tasks drop-down menu.

5. Click Execute.
Virtual Disk Task: Reconfigure (Step 2 of 3)

Does my controller support this feature? See "Supported Features."
This screen enables you to select the RAID level and size for the reconfigured virtual disk.

To Reconfigure a Virtual Disk: Step 2 of 3

1. Select the new RAID level for the virtual disk. The available RAID levels depend on the number or physical disks selected and the controller. The following
describes possible RAID levels:
¡ Depending on the controller, Concatenated enables you to combine the storage capacity of several disks or to create a virtual disk using only a
single physical disk. See "Number of Physical Disks per Virtual Disk" for information on whether the controller supports a single physical disk or
two or more when using Concatenated. Using Concatenated does not provide data redundancy nor does it affect the read and write
performance.
NOTE: You cannot reconfigure a virtual disk on a controller that is operating in cluster mode.
NOTE: On the PERC 5/E and PERC 6/E controllers, you can create no more than 64 virtual disks. After you have reached this limit, you will no longer be
able to reconfigure any of the virtual disks on the controller.
NOTE: On Linux, if you do a reconfigure on the same controller on which the operating system resides, you may experience extremely slow system
performance until the reconfigure is complete.
NOTE: You may want to review "Virtual Disk Considerations for PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, CERC ATA100/4ch, PERC
5/E, PERC 5/i, PERC 6/E, and PERC 6/I Controllers." This section contains considerations that also apply to reconfiguring a virtual disk on these
controllers.
NOTE: For a controller that has more than one channel, it may be possible to configure a virtual disk that is channel-redundant. See "Channel
Redundancy and Thermal Shutdown" for more information.
