Dell POWERVAULT MD3600I - Manual (Page 98)

• You cannot change the RAID level of a disk pool. MD Storage Manager automatically configures disk pools as
RAID level 6.
• All physical disk types in a disk pool must be the same.
• You can protect your disk pool with Self Encrypting Disk (SED), but the physical disk attributes must match. For
example, SED-enabled physical disks cannot be mixed with SED-capable physical disks. You can mix SED-
capable and non SED-capable physical disks, but the encryption abilities of the SED physical disks cannot be
used.
Creating A Disk Pool Manually
You can use the unconfigured capacity in a storage array to create a disk pool.
NOTE: Ensure that you have created virtual disks before you create a disk pool.
To create a disk pool:
1. Select the Storage & Copy Services tab.
2. Select the unconfigured capacity node.
3. From the menu bar, select Storage → Disk Pool → Create. Alternatively, right-click unconfigured capacity in the
object tree and select Create Disk Pool.
The Create Disk Pool window is displayed.
4. Type a name for the disk pool in Disk pool name.
5. Select one of these options in Physical disk security:
– Only security-capable physical disks — To create a secure disk pool from security capable physical disks.
NOTE: The Only security-capable physical disks option is available only when a security key is set up
for the storage array.
– Any available physical disks — To create a disk pool comprised of physical disks that may or may not be
security capable or are a mix of security levels.
NOTE: You can mix Self Encrypting Disk (SED)-capable and non SED-capable physical disks.
However, the encryption abilities of the SED-capable physical disks cannot be used, as the physical
disk attributes do not match.
Based on the physical disk type and physical disk security type that you have selected, the Disk pool
candidates table shows one or more disk pool configurations.
6. Locate the Secure Enable? column in the Disk pool candidates table and select the disk pool that you want to
secure.
NOTE: You can click View Physical Disks to view the details of the physical disks that comprise the selected
disk pool configuration.
7. To send alert notifications when the usable capacity of the disk pool is reaching a specified percentage, perform
the following steps:
a) Click View notification settings.
b) Select the check box corresponding to a critical warning notification.
You also can select the check box corresponding to an early warning notification. The early warning
notification is available only after you select the critical warning notification.
c) Select or type a value to specify a percentage of usable capacity.
When the configured (allocated) capacity in the disk pool reaches the specified percentage, an alert
notification in the form of emails and SNMP trap messages are sent to the destination addresses that are
specified in the Configure Alerts dialog. For more information about how to specify the destination addresses,
see Configuring Alert Notifications.
8. Click Create.
