Remove and replace the NVMe card
The NVMe card is not hot-swappable and requires a system shutdown.
The NVMe card in PCIe slot 4 is used as the SSD cache tier for the Data Domain Virtual Edition
(DDVE) VM. When you replace the NVMe card, you must reconfigure the DDVE cache tier.
Record existing SSD cache tier details
You will need the size and device number of the cache tier when you create the new data store
after replacing the NVMe card.
Procedure
1. Log in to the ACM GUI dashboard and determine the IP address for the DDVE VM.
2. Using SSH, log in to the DDVE VM as sysadmin using the common password for the
appliance.
