Add Memory
Overview
This function adds memory while the storage system is operating.
After memory is added to the memory slot of the Controller Module (CM), activate it from Web GUI.
Memory Specifications of Each Model (per CM)

ETERNUS DX600 S5 | 16 GB, 32 GB, 64 GB | 96 GB, 192 GB, 384 GB | 6 | 6 |
ETERNUS DX8100 S4 | 16 GB | 48 GB | 3 | 3 |
ETERNUS DX900 S5 ETERNUS DX8900 S4 |
16 GB, 32 GB, 64 GB, 128 GB | 96 GB, 192 GB, 384 GB, 768 GB | 6 | 6 |
ETERNUS AF650 S3 | 64 GB, 128 GB | 384 GB, 768 GB | 6 | 6 |
*1 | : | The "32 GB" memory type is a "Memory Extension" that is used in the Unified Storage environment. To register a Unified License in a customer environment, "Memory Extension" must be added in advance. |
Perform the start maintenance operation by using the [Start/End Maintenance] function before adding memory. If the operation has not been performed, addition cannot be started.
Be sure to use authorized additional parts. If parts other than the additional parts are used, operation is not guaranteed.
For the ETERNUS DX8900 S4, a license must be registered to use the added memory. Refer to the [Expand System Memory Capacity] function for details.
If the CM to which memory is to be added is a Master CM, the Master CM is switched.
The memory is added to all the enabled CMs installed in the storage system.
This function is not available for the ETERNUS DX60 S5 and the ETERNUS AF150 S3/AF250 S3.
Refer to "Memory Specifications of Each Model (per CM)" to make sure to observe the memory expansion unit when adding memory. If the number of installed memory modules is less than the number of installed memory expansion units, the installed memory modules cannot be used.
Do not add memory when Storage Migration paths are set.
- This function cannot be used under the following conditions:
The general status of the storage system is not normal
The Drive Enclosure (DE) may be blocked
Maintenance for the CM cannot be performed
A recovery operation for the CM is being performed
The Master CM cannot be switched
An error exists in another part
-
If an activation fails midway through the memory adding process for models other than the ETERNUS DX900 S5 and the ETERNUS DX8900 S4, the [Add Memory] function must be executed again.
Perform the following procedure.
Perform a maintenance for the target component that failed to be added.
Restore the memory that failed to be added back to the initial state (by performing a preventive maintenance for the target CM to remove the memory).
Refer to "Hot Preventive Maintenance" for details.
Execute this function again.
Even if an activation fails midway through the memory adding process for the ETERNUS DX900 S5 or the ETERNUS DX8900 S4, the process can be resumed from where it was interrupted by executing this function again after a maintenance for the target component that failed to be added is complete.
For the ETERNUS DX900 S5 or the ETERNUS DX8900 S4, memory is added in descending order from the CM (CE#x CM#y) that is installed in the CE with the largest number. Add the memory in the Master CM last.
The physical capacity of the installed memory in the CM is displayed in the "Memory Size" field on the [Controller Module Detail] screen. Refer to the [Controller Module] function for details.
