Current Mode—Indicates if the hard drive is assigned to an enclosure or to a single compute node slot.
● Enclosure-Assigned—In this mode, you can assign an entire storage sled to one or more compute node slot.
NOTE: You cannot assign storage when a redundant SAS IOM setup is temporarily degraded to nonredundant state.
NOTE: The storage enclosure is assigned to the slots of the compute slots and not to the sled itself. If a compute sled is
replaced with another sled on the same slot, then the storage enclosure gets assigned to the new sled automatically.
However, if you move the compute sled from one slot to another, you must remap the storage to that sled.
● Drive-Assigned—In this mode, you can select a hard drive slot and assign it to a compute node slot.
CAUTION: Assigning a hard drive to a compute node slot may result in loss of data.
NOTE: If the SAS IOM is unavailable, the Current Mode is displayed as Unknown. This indicates that there is a
communication failure and no assignments can be done.
● The Current Slot Assignment(s)—In this mode, you can view the number of storage-compute sled mappings.
NOTE: When a SAS IOM is power that is cycled, the storage-IOM mapping information is displayed after five minutes.
NOTE: The storage assignment times vary, based on the number of compute slots that are selected.
NOTE: Replace the storage sleds one at a time, to retain the storage mapping after replacing a sled with empty service
tag.
Assigning drives to a compute sled
Using the Drive-Assigned mode, you can map the drives in a storage enclosure to a compute sled slot. If the compute sled
fails, the drive remains assigned to the slot. If the sled is moved to another slot on the chassis, reassign the drives to the new
slot. To configure RAID on the drives, use the iDRAC web interface, a server configuration profile, or an operating system
deployment script, after the drive assignment is complete.
CAUTION: Before you assign a drive to a slot, ensure that the data from the drive is backed up.
NOTE: The HBA330 controller card does not set a status for the hard drives when the hard drives are removed from the
storage sleds after the hard drives are assigned to compute sleds.
To assign a drive:
1. From the Devices drop-down, select Storage.
2. Select the storage sled from the list of the storage devices.
3. Click View Details.
The storage Overview page is displayed.
4. Click Hardware.
The drive list is displayed.
NOTE: Ensure that the Drive-Assigned mode is selected.
5. Select one or more drives and click Assign Drive to Slot.
The Assign Hard Drive to Compute page is displayed.
6. Select the slot and click Assign.
When a drive is reassigned from one compute sled to another, the enclosure status and spin-up state of the drive is the
same. If a drive is in power-savings mode, the status of the drive is displayed as "starting".
Assigning storage enclosure to a compute sled
Using the Enclosure-Assigned mode, you can assign a storage enclosure to one or more compute sleds with HBA330
minimezzanine adapter. Using this mode, you can also assign a storage enclosure to an empty slot. If the sled is removed and
installed to another slot the assignment must be performed again.
CAUTION: Before you assign an enclosure to a slot, ensure that the data from the drive is backed up.
NOTE: Systems with H745P MX controller only support a single storage enclosure mapping.
