Abstract
FlashSystem storage arrays (FSNs) contained within the Integrated Analytics System (IAS) each contain two batteries which are designed with a finite end-of-life. When a battery nears its expiration date, it will generate a HW_SERVICE_REQUESTED alert and should be replaced.
Both batteries in a single Flash array CANNOT be replaced at the same time. However, all Flash arrays in a given appliance can have one of those two batteries simultaneously replaced. To simplify this process, IBM service should replace all Flash array batteries in an appliance across two service visits (separated by at least 24 hours). These are concurrent service procedures and can be done at any time with no impact to system operation.
Content
The FlashSystems storage arrays (FSNs) contained within the Integrated Analytics System (IAS) contain two externally facing, concurrently repairable Li-Ion batteries These batteries have an expected life of 4 years. "Life" of the battery is measured from the date a battery is first installed into a system, whether at the manufacturing facility or when a replacement battery was installed in a system on-site. A Flash Storage Array (FSN) must have at least one healthy, charged battery in order to remain online and operational. Therefore, replacing the expiring batteries in an appliance will require two different service visits, separated by at least 24 hours.
This service procedure applies to all IAS systems (MT=3452), both M4001 and M4002 models. The replacement FRU is the same for both FlashSystems AE2 and AE3 models (used in M4001 and M4002 appliances respectively).
When a storage enclosure battery reaches 120 days before its "end of life" date, a warning message is issued from the FlashSystem. This WARNING will generate the following alert:

If the customer has Call Home enabled, this should automatically open a Support case. Otherwise, the customer will receive an email notification informing them IBM Support should be contacted. Once IBM Support receives a case such as this, they will schedule two service calls to replace all the batteries within the given appliance. There are three things you need to know about these alerts.
- A given Flash array must, at any given time, have at least one fully charged battery. Since these are Li-Ion batteries, they can not ship fully charged. Therefore a new battery needs some amount of time to charge before the second battery for that array is replaced.
- These replacements are concurrent and non-disruptive.
- These alert warnings occur approximately 120 days prior to actual End-of-Life. So which response to the alerts should be timely and should not be ignored, if they are done next week or even later in the month that is okay. However, the WARNINGs should NOT be ignored.
When you receive one of these alerts from your IAS appliance, should your system have the Call Home function enabled, a support case will automatically be opened and you will be notified by IBM Support to arrange for two service visits. If you have not enabled Call Home, please open a support case for this alert at https://www.ibm.com/mysupport/
