Adaptec ASR-8405 SGL — управление дисками и настройка RAID-контроллеров [90/117]

Adaptec ASR-8405 SGL [90/117] Managing the maxcache pool

SATA interface. For more information about uninitialized devices and controller modes,

see General Controller Settings on page 91.

To begin uninitializing a disk drive, select Uninitialize Drives from the Logical Device Conguration menu,

then type Y to continue.

Managing Global Hot Spares

Note: For Adaptec Series 7 and Adaptec Series 8 controllers, this option is available

in the uEFI interface only.

A hot spare is a disk drive that automatically replaces any failed drive in a logical drive. A global hot

spare is not assigned to a specic logical drive. It protects any logical drive on the controller (except

RAID 0 logical drives). You can create and delete global hot spares even if no arrays exist.

To create and delete global hot spares:

1. Select Global Hotspares from the Logical Device Conguration menu.

The Global Hotspare Management window opens.

2. Using the arrow keys, select a drive from the list. Existing hot spares are highlighted.

3. Press Ins to create a new global hot spare. Press Del to delete a hot spare.

4. Press Enter to save your changes and return to the main menu.

Creating and Managing JBODs

Note: This option is available on Adaptec Series 6 controllers only.

Follow the on-screen instructions to create and manage JBODs.

Creating a New JBOD

A JBOD disk appears as a physical disk drive to the operating system. A JBOD disk is not redundant and

not bootable.

To begin creating a JBOD, select Create JBOD from the Logical Device Conguration menu. All the

supported disk drives are displayed. Select a disk drive and Enter.

Managing Existing JBODs

To delete a JBOD or morph a JBOD into a simple volume, select Manage JBODs from the Logical Device

Conguration menu.

From the Manage JBODs menu, you can:

• Morph a JBOD into a simple volume.

• Delete a JBOD

Note: When you delete a JBOD, you lose all data on that disk.

Converting a JBOD Into a Simple Volume

You can convert any JBOD into a simple volume.

1. Select Manage JBODs from the main Logical Device Conguration menu.

2. Select the JBOD that you want to morph into a simple volume and press Ctrl+V.

Managing the maxCache Pool

Note: This option is available on Adaptec Series 6Q controllers only.

Adaptec maxCache uses the compatible Solid State Drives (SSDs) in your system as fast cache memory

for read-intensive operations. Before you can enable maxCache read caching on a logical device (see

Modifying Cache Settings on page 88), you must assign at least one SSD to the maxCache pool.

Note: You can congure the maxCache pool only if you have one or more compatible

Solid State Drives installed on the RAID controllers in your system. For a list of
