HP IO Accelerator Management Tool 85
Use Attach to restore the operating system access to the IO Accelerator.
Detaching mixed attached/detached devices
If you select a set of IO Accelerators to detach where some are attached and some are detached, the
Confirm Detach dialog box displays a list of the drives and their statuses.
When you click Detach, the IO Accelerator Management Tool disconnects only the attached devices
(those marked Ready).
Low level format
Your IO Accelerator comes pre-formatted so it is not usually necessary to use this option. However, you
would use it if you:
• Must reformat the drive to change its logical size to enhance write performance.
• Are instructed to do so by HP Customer Support.
The IO Accelerator Management Tool performs a low-level format that is different from a format
performed by an operating system using standard disk management utilities. You do not need to perform
an IO Accelerator Management Tool low-level format to create an operating system-specific volume on the
device.
CAUTION: Formatting an IO Accelerator destroys any data still on the device. If you have not
backed up data to another device, choose Cancel to abort the format.
To format an IO Accelerator:
1. Select one or more IO Accelerators from the Device Tree.
2. Click Low Level Format.
3. Select which type of format you want to perform.
o Maximum Capacity—Creates the maximum possible capacity for user data on the device. This
format is standard on a new IO Accelerator.
o Improved Write Performance—Formats the device for increased write performance at the cost of
approximately 30% capacity.
