About this task
Upgrading DD9410 and DD9910 systems from single node to HA requires removing the metadata SSDs from the front of the
existing node. In an HA pair, the metadata storage must be shared between the nodes. Do not put the SSDs from the front of
the existing node into the SSD shelf. The SSDs removed from the existing node are no longer required.
Complete the following steps to remove the SSDs.
NOTE:
When the existing node is powered back on after removing the cache SSDs and installing the FS240 SSD shelf, the
system displays an alert that the cache SSDs are missing from the existing node. This is normal behavior, the system will
recognize the FS240 as the location for the cache drives after the HA configuration is complete.
Steps
1. Identify the SSDs to remove from the existing node.
