Replace the NVRAM module or NVRAM DIMMs - AFF A700 and FAS9000
The NVRAM module consists of the NVRAM10 and DIMMs and up to two NVMe SSD
Flash Cache modules (FlashCache or caching modules) per NVRAM module. You can
replace a failed NVRAM module or the DIMMs inside the NVRAM module. To replace a
failed NVRAM module, you must remove it from the chassis, remove the FlashCache
module or modules from the NVRAM module, move the DIMMs to the replacement
module, reinstall the FlashCache module or modules, and install the replacement
NVRAM module into the chassis. Because the system ID is derived from the NVRAM
module, if replacing the module, disks belonging to the system are reassigned to the new
system ID.
Before you begin
• All disk shelves must be working properly.
• If your system is in an HA pair, the partner node must be able to take over the node associated with the
NVRAM module that is being replaced.
• This procedure uses the following terminology:
◦ The impaired node is the node on which you are performing maintenance.
◦ The healthy node is the HA partner of the impaired node.
• This procedure includes steps for automatically or manually reassigning disks to the controller module
associated with the new NVRAM module. You must reassign the disks when directed to in the procedure.
Completing the disk reassignment before giveback can cause issues.
• You must replace the failed component with a replacement FRU component you received from your
provider.
• You cannot change any disks or disk shelves as part of this procedure.
Step 1: Shut down the impaired controller
